What Lubricant To Use To Clean The Ceramic Seal Of T Het Pooll Pump
Swimming Puddle Filter pumps
The heart of your apportionment system, your puddle pump pulls water from ane or more suction ports (skimmers and main bleed), and pushes it through the filtering, heating and sanitizing equipment, and back to the pool through the wall or floor returns, force per unit area cleaners or water features.
The pool pump has the almost important job on the pool equipment pad, considering when the pump is not working, aught else works either.
How Do I Know What Pump is Right for My Pool?
Opposite to selecting a puddle filter, a bigger pump is not always a good thing. Unless you have been brash by a pool professional, or are otherwise certain that your existing pump was undersized, information technology would be wise to continue the aforementioned horsepower equally you lot have now.
Dissimilar pumps produce different flow rates, even if they are the aforementioned horsepower. A 1hp Hayward pool pump will not produce the same period charge per unit as a 1hp Pentair pool pump. More than important than matching pump horsepower, is matching pump flow rates. For case, a 1hp Hayward Superpump is capable of 75 gpm, only a 1hp Pentair Whisperflo is capable of 115 gpm. This does non brand the Pentair pump a 'improve' pool pump, on the contrary, period rates that are also loftier can damage your filter and pipage, and result in ineffective filtration.
If the existing pump has done you well, it is easiest to replace a failed puddle pump with the exact same make/model/size of pump. The height and length is also the same, which makes the plumbing job much easier. A dissimilar pump will ordinarily require some aligning to fit the pipes to the top of the front end inlet and the length to the back discharge port. Dimensions of most pumps can exist plant on our pump pages, and some exercise match up, for example Pentair SuperFlo matches upwardly to Hayward Superpump, or the Hayward Superpump VS pumps, and Whisperflo pumps can be swapped out with Pentair Intelliflo VS pumps.
How practice I know what Horsepower my pump motor is?
The horsepower should be listed on the nameplate (left) of the pump motor (in very tiny letters - hp). If the motor nameplate is burnt or worn off, a printed role number from the impeller tin can tell united states of america which hp pump motor y'all have. This is because unlike horsepower pool pumps employ different impellers. A motor manufacturer motor model number listed on the label can as well be cross referenced with a quick online search.
Selecting a New Pool Pump
When ownership a swimming pool pump, look for and buy a pool pump made by a major manufacturers; that is, Hayward, Jacuzzi, Pentair (American, Pac-Fab, Purex, Sta-Rite) and Waterway - well known marketplace leaders. Other pumps of less recognizable brands are likely imported knock-offs of dubious quality, with non-existent replacement pump parts availability.
Remember that all pool pumps are unlike in hydraulics, shape, handbasket, lid, and colors. However, these may or may not matter a whole lot. Read on for more than substantial ways to discern betwixt filter pumps.
You volition find that there are low caput pumps for aboveground pools and medium and loftier head pumps for inground pools. The term "head" refers to the period rate, in a backwards kind of way.
In a higher place ground filter systems usually use a Low Head pump like a Dynamo, Hullo-Flo or Power-Flo. Non cocky-priming, these are installed below water level. Inground pools from fifteen,000-25,000 gals can use a Medium Caput pump like a SuperPump, a Superflo or Magnum Strength.
Pools over 25,000 gals could peradventure use the Loftier Head pumps like, Super II, Challenger, or the Whisper-Flo, with large plenty plumbing and filter size. The motors used on puddle pumps are all well-nigh the same, most made by AO Smith, Century or Emerson. There have been many innovations in pump technology in the recent years, with the nigh notable beingness Variable Speed pumps, which utilize a completely different motor blazon.
For Variable Speed pumps to piece of work well, you want to be able to apply all speeds, and if you oversize a VS pump to your pool plumbing and filter size, information technology can crusade bug. Fortunately, there are smaller medium head VS pumps, equally well as larger high caput VS pumps.
Aboveground and Inground pools over 20,000 gallons could employ a medium head VS pump, like the MaxFlo VS, Superpump VS or the SuperFlo VS. Larger pools, or pool/spa combos and pools with h2o features can use a high head VS pump, like the Ecostar or the IntelliFlo. Remember when selecting a new pump to match hp, and pump type and flow rates. Use the Pump Flow Rate Charts, (encounter below) also known equally Performance Data. This is based on a sample 'anxiety of head' of 30 or 40 feet. This is the only true way to compare pool pumps to each other.
How much Head or Resistance is in your organization? That'southward hard to calculate without a lot of math, but to compute resistance equally measured in anxiety of head, you lot would need to know the resistance value of each length of pipe, every plumbing fitting, valve, pump, filter, heater, etc. But allow's keep this unproblematic, shall we? If your pool plumbing is very simple, and your pump is fairly close to the pool, you may have 20-xxx feet of head overall. If you accept three or four lines coming into the pump, a large filter and perhaps a heater, you may have 30-40 feet of head overall. If your pool is quite complicated, with lots of large pipes and extra equipment or h2o features, with a filter tucked abroad far from the puddle, y'all may take 40-50 ft of caput overall. If you tin find the original info from the pool builder, the total resistance may exist listed on the spec sheet.
As Americans, it'south natural to want the big 5-8 power plant, merely a pump that is too powerful could actually prevent filtration while damaging the filter and heater. Pipes or fittings can divide, filter internals can plummet, and heaters tin exist stripped of copper.
When matching pumps to filters, bank check the Pattern Flow Rate of the filter on the filter label. The average flow for the pump you select (at a given level of resistance) should be within 10% of the pool filter's Design Menstruation Charge per unit.
Remember also, that a smaller hp motor is going to describe fewer amps, which is going to price less to operate. If you are careful to match upwardly menstruum charts, y'all could actually reduce the hp required, while increasing the head of the pump. For instance, a i/ii hp Whisperflo produces near the same corporeality of flow as a 1-i/2 hp SuperPump, at a given resistance, or head. And so, yous could replace a Super Pump with a smaller Whisperflo pump; reducing your amp depict and cutting electrical expense in one-half.
When selecting a new pool pump, if you aren't buying the same make/model, keep it close to the original specifications, and use the Pump Period Charts. Most systems could handle a small increase in pump size, especially if y'all are replacing the filter with a larger one, but be careful to match pump flow charge per unit with your filter's design flow rate. And think that the flow charts are assuming a clean filter, when in reality, your overall system resistance will increase as the filter pressure rises.
How practice pool pumps work?
The water is pulled from the puddle by a brass or plastic impeller that is shaft driven by an electric pump motor. On the mode to the pump, the water is nether a vacuum, which creates the suction. After the water leaves the impeller, the water is put under pressure, being pushed until it is released into the pool. The design of the impeller and impeller housing creates the suction required to lift water, and the pressure level to force it through the filter. An air tight suction side is necessary (without air leaks) to create the vacuum to pull the h2o from the pool.
The electric motor is powered from a breaker on your electrical console (or fuse box), at 115 or 230 volts. Usually motors over 2 hp need 230V ability to operate, and virtually smaller hp pumps convert to accept either 115 or 230 volts. Above ground pumps are oftentimes 115V only, and have a pump power cord for GFCI outlet power.
Electrical consumption will vary past pump, and manufacturers have been designing motors and pumps (the wet end) which are more efficient and consume much less energy than older pumps. Energy efficient motors depict fewer amps; the smaller the amperage draw of the motor, the less expensive it is to operate. On motors with reversible voltage (115V/230V), Amps is listed on a motor nameplate with two numbers, i.due east. 16/viii. The first number refers to the amps used to get-go the pump with 115V, and the lower number is when the motor is wired with 230V.
How long do motors last?
Pool pump motors typically last about 8-10 years before needing either rebuilding or replacing. Noisy, screeching front and/ or rear bearings volition permit yous know when yous need to exercise something. Read below for more information on noisy pool pumps.
Many people replace the entire pool pump, when merely the motor is bad. The plastic parts of the pool pump, the front half, known as the wet end, do not generally wear-out or neglect, and could last for the life of the pool, with an occasional replacement of small parts like the handbasket, pump lid o-ring or drain plugs.
Rebuilding a motor is a replacement of the bearings and shaft seal, which could be a wise direction if the motor is only a few years old. Pool pump motor bearings are sealed, and do non require lubrication or maintenance. There are several sizes of bearings and seals, with different motors using different sizes.
Pump motors are built for continuous duty, in the outdoors, simply will last longer if shielded from conditions and backlog wet. Removing a pump for wintertime storage tin preclude the rust that develops between the stator and rotor on pumps left outside during periods of non-employ.
Pool Pump Troubleshooting Guide: A guide to help you with some of the almost mutual problems that can occur with pool pumps.
How to Prime number an Inground Pool Pump
Answer:Remove the pump cover lid and fill the pump and pipes with water. Replace pump chapeau tightly. Open up air bleeder on filter tank and turn on pool pump. If pump does not catch prime inside sixty seconds, repeat steps one-3.
Lube pump hat o-ring and tighten the pump hat very tightly. Check the areas earlier the impeller for air leaks; the pump needs to be air-tight on the suction side of the impeller.
How to remove a Stuck Pump Cover or Hat
Answer:Open the filter air bleeder to release a vacuum air lock. Close suction and return valves to remove a h2o lock. For lids with raised edges, lay a long screwdriver or board betwixt the edges. For lids with lock rings, try a large strap wrench, or wrap a cloth around the ring. When all else fails, tap lid gently with a rubber mallet, in a ccw management.
Clean your pump chapeau o-ring with a soft rag, and keep lubricated with a Teflon pool lube for smooth performance, ameliorate sealing and o-band protection.
How to Clean a Clogged Pool Pump Impeller
Reply:Remove pump lid and pump basket. Achieve into impeller housing with a minor screwdriver; rotate in a ccw direction. Scoop out floating and sunken debris by hand. Reassemble and start pump to see if filter pressure is normal. When all else fails, open upwards pump past separating the seal plate and motor from the pump, removing the diffuser, and reaming the impeller vanes with a stiff wire.
Be sure thepump basket is seated fully and oriented properly, some have a front hole, and some lock into place with a quarter plow or marshal with a ridge in the pump trunk.
How to Empty a Pool Pump Basket
Respond:Close off pump, shut off skimmer and drain valves. Remove pump lid comprehend. Lift pump handbasket straight out (some baskets twist ¼ turn to unlock first). Gently tap the basket upside downwardly to remove debris. Replace basket correctly and fully, replace pump lid tightly.
When replacing the pump lid, cheque the pump lid, o-band or gasket, to be sure information technology is clean and seated properly in the groove.
How to Find a Pool Pump Air Leak
Answer:Check that the puddle water level is at the normal level. Bank check that skimmer weirs are not stuck in an up position, blocking water flow. Shut pump off, clean and lubricate pump lid o-ring, and supercede pump chapeau very tightly. With pump running, shut off power while looking closely for a quick spurt of water, from around the pump chapeau or from the pipe that comes into the pump. Spray foam shaving cream around the pipe that leads into the pump, to see if it sucks into the pump slowly, while the pump is running. Pressurize the arrangement with a Drain Rex™ in the skimmer, and a closed filter valve or return valve, after the pump.
The most common air leak is a loose pump lid, and the second most common is a loose incoming pipe fitting. Bubbles in the pool, or difficulty priming a pump are signs of an air leak, which will e'er be on the suction side of the impeller.
A proficient play a trick on in locating an air leak is to shut off the motor when it'due south under total pumping head pressure, and wait for water to spray back out of the void where the air was entering. You accept to be quick to take hold of this spray-back, looking closely. If that didn't piece of work, you can purchase a Drain King at your local hardware shop. This connects to a garden hose and puts the line under pressure. Push the Drain King into the skimmer, and close off other suction lines (skimmer and main drain valves). Remove the pump lid and use a plug or hold a tennis ball to plug up the pump entrance. Turn on the garden hose to allow pressure level to build up in the lines before the pump handbasket and squirt out (or drip) at the source of the leak. You tin as well put the multiport valve on the Closed position, or close render side valves and pressure level examination the entire system in this manner. If you detect water leaking anywhere earlier the pump discharge pipage, that is the source of the air.
Make certain the water level in the pool is high enough, and that the skimmer weir is non stuck in the upward position. Check that the incoming and outgoing valves are in the open position. If you suspect a clogged line, you can as well use a Bleed Rex to pressurize the line backwards from the skimmer towards the pump and remove foliage/debris obstructions.
How to Wire an Inground Puddle Pump
Respond:Shut off ability to the pump timeclock or switch past flipping the circuit breaker. Remove the rear cover of the new inground pump motor. Remove the conduit connector from the quondam motor, and screw into the new motor. Push the 3 wires through the connector and tighten the lock nut. Connect the green wire to the footing screw, and the other 2 wires to the big brass screws or spade terminals, labeled L1 and L2 (either wire). Connect the bare copper wire, the bonding wire, which connects the filter and other equipment, to the brass bonding lug on the front end/top expanse of the pump motor.
Inground puddle pumps come up ready to wire 230V. Reversible motors allow a switch to 115V, post-obit instructions on the motor label plate.
How to Supervene upon an Inground Pool Pump Motor
Answer:Buy a correct inground pump motor (frame, voltage, hp), and shaft seal. Close off power at billow, remove pump housing bolts, or a clamp ring or lock ring. Slide motor and seal plate backwards, out of the pump housing. Remove the impeller by preventing the shaft from turning, with an open end wrench on the rear of the shaft, and so spinning the impeller off in a ccw direction. Remove the iv bolts that connect the motor to the seal plate; remove the seal plate. Knock out the onetime shaft seal half in the center of the seal plate. Remove motor cover plate, disconnect wires, loosen conduit connector lock nut, slide the wires out of the motor. Remove the conduit connector and screw into new motor. Printing the round ceramic shaft seal half into the seal plate; bolt seal plate to new motor. Slide the spring shaft seal half over the impeller, and spin the impeller onto the shaft. Push wires through the conduit connector and connect the ground wire to the green basis screw, and the other two wires to terminals L1 and L2 (either wire). With diffuser and o-rings in place, slide the motor dorsum into the housing, and clench or bolt the seal plate to the pump housing. Make full pump with h2o and test performance.
Exist certain to select an exact friction match motor for your inground pool pump motor. You cannot increase horsepower without likewise replacing the pump impeller.
How to replace an Inground Pump Shaft Seal
Answer:Buy the correct OEM or generic shaft seal for your inground pump. Shut off ability at breaker, remove pump housing bolts, clamp ring or lock ring. Slide motor and seal plate backwards, out of the pump housing. Remove the impeller by preventing the shaft from turning, with an open end wrench on the rear of the shaft, and so spinning the impeller off in a ccw direction. Remove the 4 bolts that connect the motor to the seal plate; remove the seal plate. Knock out the old shaft seal half in the centre of the seal plate. Press the round ceramic shaft seal half into the seal plate; bolt seal plate to new motor. Slide the bound shaft seal half over the impeller, and spin the impeller onto the shaft. With diffuser and o-rings in place, slide the motor dorsum into the housing, and clench or bolt the seal plate to the pump housing. Fill pump with water and test operation.
Shaft seals are 2 pieces, the leap half and the ring half. The spring one-half has a difficult plastic side that makes contact with the ceramic confront of the band one-half.
How to replace an Inground Pump Capacitor
Answer:Buy an verbal replacement capacitor by matching the MFD or UF rating. Close off power to the pump timeclock or switch, by flipping the circuit billow. Remove the rear embrace of the new inground pump motor. Utilise a ¼" nutdriver to loosen the capacitor retainer band. Utilize needle olfactory organ pliers to remove each wire, making notation of their location. Replace each wire onto the new capacitor in the exact same location as before. Reattach capacitor retaining ring and motor rear cover.
Remove and replace each wire one at a time, or make a diagram, to prevent mis-wiring. Before replacing encompass, tuck capacitor wires properly to avoid contact with cover or switch.
Inground pool pump troubles tin can happen to anyone at any time. The motors will usually last for x years, before they burn down out, or begin to run very loudly, indicating worn bearings. At this point yous can replace just the motor and shaft seal, or replace the entire pump.

Leaking pump?
A very mutual trouble is the threaded fitting carrying water out of the pump shrinking from oestrus and allowing water to baste, run and and so spray. This can be replaced with a high temp fitting to forbid its reoccurrence. You lot'll need to cutting the pipe later on the pump, supervene upon the MTA (male threaded adapter) using an appropriate thread sealant, and reconnect the plumbing equipment to the pipe using some new pipe and a coupling or matrimony.
H2o may also leak from a worn out mechanical shaft seal. The pump seal is the separation between the wet end and the dry finish (motor) of the pump, and allows the motor shaft to enter the pump, and spin freely without leaking water. Ozone and Salt resistant pump seals are fabricated with materials that can better resist deterioration from salt h2o or ozone introduced in front of the pump.
A blown shaft seal is axiomatic from water dripping down the back of the seal plate, and onto the basis, merely should be distinguished from a leaking pipage fitting as described above or a leaking clamp ring which holds the seal plate to the volute, or impeller housing. These leaks can too drip straight off the bottom of the pump, mimicking a leaking shaft seal.
Air in pump basket?
The pump is meant to operate air free, to create the necessary vacuum. Later on some fourth dimension, you may notice air in the pump basket, especially if y'all have a clear hat to observe such things. Air in the pump will reduce filtering efficiency, let dangerous air to build upwards in filter, and can prevent your pump from communicable prime (existence able to move h2o).
The problem is usually institute in front of the pump, above-footing. Rarely exercise we have to await underground for the source of the air. The most common cause is the pump inlet fitting being loose, commonly shrunken slightly from heat, or installed without thread sealant.
Air in the pump handbasket can exist caused past something as simple as the water level being likewise low in the pool. Also, if the skimmer weir is stuck in the up position, it volition block the water and cause the skimmer to drain and take in air. Likewise bank check that the pump basket lid is secured very tightly and the o-ring is lubricated with Teflon lube. Drain plugs without Teflon tape, or missing an o-ring (used on some pumps) volition also cause the pump to depict air.
Locating an Air Leak
Make sure the strainer lid is on tight, with a clean, lubed o-band. Also check that all drain plugs are tight. This void will ever be earlier the impeller. Subsequently the impeller is what we call "the pressure side". Any leak or void subsequently the impeller will leak h2o out. Any leak or void prior to the impeller (in forepart of the pump impeller) will draw air in when the pump is on. A puddle pump will "pump" air if it can; it is the path of least resistance. So, your system needs to exist almost airtight to run properly.
Pump is not pumping water like usual?
If it's not an air leak, (run across above) it's probably an obstruction. Could be a dingy pool filter, or closed valves. Check your skimmer baskets for heavy debris. Make sure the pump handbasket is clean and properly positioned, and that the pump lid is on very tight. Some types of pumps take a pump strainer basket that locks into place to preclude the basket from floating and blocking the entrance, or allowing droppings to bypass the basket, and a clogged impeller.
When the pump basket is cracked it tin also permit debris to clog the pump's impeller. If the pump basket is cracked or damaged, information technology should exist replaced. To check the impeller, turn off the motor, remove the pump basket and accomplish into the volute and experience if information technology is chock-full with debris. If you cannot feel for certain, yous may need to remove the motor from the pump to properly audit the impeller. Many times yous need only remove a clamp band or 4 to 6 nuts, to dissever the motor from the pump. More than on cleaning a clogged pump impeller below.
Another way to dominion out a clogged pump impeller, or an obstruction after the pump is to remove the pump lid, fill the pump with water, and plow on the pump for a few seconds. If you see the h2o get sucked down at least halfway, like a flushing toilet, you can assume that the impeller and pipes are clear. If the water simply vibrates, or only goes down an inch or so, either the impeller is very clogged, or cleaved, or in that location is an obstacle afterwards the pump, such equally a dingy filter, closed valves or plugged lines.
Noisy pump motor?
Inside of your pump motor are a front bearing and a rear bearing, attached to the front and rear of the motor shaft (which is attached to the rotor). These bearings are sealed and cannot be re-packed or re-lubricated. They are replaced when they begin to scream and screech.
Bearings can go damaged when the pump has run dry out and overheated, or if the pump is put under consistently heavy loads, or if the pump is dropped or something heavy falls on the motor. A local motor shop can replace the bearings for you, ordinarily for effectually $100, or yous can buy your ain replacement bearings and supplant them yourself, with the aid of bearing pullers. Pump motor bearings are stamped with a 3 or 4 digit number that indicates their size. It tin can be difficult to determine the right bearings without actually opening up the motor, although near pump motors use 203 and/or 304 bearings.
To make certain information technology'south the bearings, remove the motor from the pump, and turn it on. If it still screeches while disconnected from the wet end of the pump - it is going to be the bearings. Rebuild it, with new bearings and shaft seal, or supersede information technology with new motor and shaft seal. Or you can replace the entire pump.
A noisy pump tin can also mean cavitation. This sounds less like screeching and more than like growling, like information technology's gargling stones. This status is acquired past starving the pump for water. If possible, open more valves, or find the cause of the obstruction that is blocking water menses into the pump. It may exist a clogged impeller, or if a new pump, it may be too powerful for your plumbing ready-up.
Finally, noisy pumps can be the sound of components hitting one some other. The impeller tin can, on stub shaft models, come loose, and hit against the impeller housing. The internal fan tin pause and hitting against the motor side. Both instances will resolve themselves. At 3450 rpm, information technology won't take long for the fan to wearable down or the impeller to break.
Motor will non start or turn on
First check that you have ability. Is the billow on? Reset information technology by turning it all the way to the off position, and and then dorsum on over again. Is the fourth dimension-clock on? All switches on? Apply an electric meter to exist sure that voltage is correct, +/- 10%. With the power off, check that all electrical connections (where the power wires connect) are tight on the timeclock and on the other end on the motor terminal board. Bank check for visual show of corrosion or infestation of ants or bees. If comfortable doing so, y'all can turn the power on, and using an Air-conditioning voltage test meter, verify that there is power going all the mode to the motor. If there is proper ability coming into the motor, as tested on the terminal board, but no noise whatsoever, the motor may have go shorted beyond its windings. Time for a new motor if this occurs.
Motor hums only will not start
If this is the start start upward afterwards a long time off, such every bit during spring opening, there may exist rust built upward between the stator and rotor, within the motor – this we call a 'frozen' motor. If you take an open volute, with visual access to the shaft, employ straight pliers to move the shaft dorsum and forth, until it spins free. If you cannot see the shaft, as is the case with most pool pumps, access it through the rear of the motor, placing a wrench on the shaft to turn it back and along to intermission the rust that has formed inside the motor. Y'all will need to loosen either the capacitor (9 o'clock) or thermal overload switch (12 o'clock) to be able to get a wrench (usually vii/xvi") on the slotted stop of the motor shaft.
Another rare cause is that the impeller may be clogged with so much droppings that it stops the motor shaft from turning. Turn off the power, and spin the motor shaft. If information technology won't turn freely, remove the motor from the pump and make clean the impeller. If the shaft spins freely, check the capacitor. If it is a stub shaft type motor (with non-threaded shafts used on older contumely pumps), cheque that the impeller is non striking the impeller housing.
The start capacitor is the black cylinder on the dorsum of the motor, which gives the motor the extra oomph it needs to start upwards. Check the capacitor for white residue or oily discharge or for bulging or groovy. Sometimes even a fine looking capacitor can be bad.
Capacitors can be tested with an Ohm meter. Commencement remove the leads with pliers, then discharge whatsoever stored power by touching 2 opposite terminals at the aforementioned fourth dimension with an insulated screwdriver. If there is stored power information technology may make a popping sound. Gear up your meter to Ohms, on the 1K scale, and bear upon the leads to two terminals. A good capacitor will slowly ascension on the meter, while a dead capacitor will remain at zero. Replace with a new capacitor of the same microfarad rating. This is printed on the capacitor, for case 161-193 MFD, which is the capacitor size used for ¾ - ane hp motors.
Finally, low voltage tin be a cause of a bustling only non starting motor. New motors are wired 220 volts, so if yous hook it up to 110 volts, it will only hum, or cycle. Or peradventure one of the ability leads is loose, corroded or shorted. Check with a Multimeter to verify the right voltage, with a variance of ten% immune, either higher or lower.
Motor Cycling
When puddle motors run for a short while, shuts itself off, and turns itself back on later, it may be overheating. Normal motor temperature is over 140 degrees, and so all motors run hot to the touch. Simply a cycling motor may point that the thermal overload is kicking it off. If this motor was just replaced, make certain that the electrical supply connections are right and the wire size is correct for the voltage it is carrying. Low voltage tin can also cause overheating. Inadequate ventilation can cause overheating, and so make sure that the air vents are unobstructed, and clear abroad whatsoever mulch or leaves. Usually, old motors that suddenly begin to overheat will need to be replaced. They usually have a short inside, across the windings, and motors are merely not rewound anymore like they were in the sometime days.
Plumbing in a new pump motor...
Cut the pipes going into the forepart of the existing pump, and the pipe coming out of the elevation. Important: Cull your cut location so as to let room on either side of the cut to glue on a repair coupling or marriage. Remove the wires and the conduit adapter from the rear of the motor. Remove the MTA fittings threaded into the front and top of the old pump. Using Teflon tape and perhaps also silicone sealant, thread in the fittings y'all removed from the old pump, unless y'all doubtable that they have shrunk. Note: Practise Non Over-tighten; turn simply 1-1/2 turns past hand tight. Using pump unions or simple slip x slip couplings, reconnect the pipes you cut. On PVC fittings, use a PVC primer and good, fresh PVC mucilage for all plumbing, and be sure to apply force per unit area fittings, which accept deeper sockets than drain fittings.
Wiring up a new pump motor...
There is a small wiring diagram printed on the motor label for your reference. First, spiral in the conduit adapter onto the dorsum of the motor. Remove it from from the sometime pump and spiral into the 3/4" threaded hole where the wires enter the back of the motor. Remove the back of the motor and run the wires in through the adapter, and tighten down the threaded nut to secure the wires and keep out moisture and insects. Afterward running the wires into the motor, on the right side, a terminal board that has 2 brass screws for clamping down the 2 wires (lines) coming in. It doesn't matter which wire goes to which spiral, L1 or L2. Above the final board, there is a green screw that is for clamping down the basis wire.
All pump motors which are 115/230V, or 'reversible', are wired to receive 230 Volts from the factory. This is to prevent damage to the motor past attaching 230V to a motor gear up to accept only 115V. A 230V motor is prepare to accept 2 lines (wires) carrying 115 Volts each. So, y'all need to know if you accept 115 Volts coming in, or if information technology'due south 230 Volts. Usually (but not always) 230 Volt service will have two wires of the aforementioned color, (and one green basis wire), while 115 Volt service will have perhaps one red (hot), one white (neutral), and one green. You should use a meter to be certain, or you can look at the circuit breaker. If 2 wires come up off of one breaker, then you take 230 Volts. If i wire is connected to a breaker, and the other to the 'neutral' Osculation bar, then information technology is 115 Volt service. Or look at the voltage plate on the old motor and run across how information technology was hooked up. Does the terminal lath wiring (not your ability wires, but the other wires attached) lucifer the Depression Voltage diagram (115 Volt), or match the high voltage diagram (230 Volt)?
If you lot have 230 Volt service, hook up the wires coming into the motor to the contumely terminals in the same way as described above. If you have 115 Volt service, follow the instructions on the motor label to switch the motor to receive 115 Volt. This is a very piece of cake switch of simply 1 wire. Once again, a reversible motor comes manufacturing plant wired for 230 Volt. If you are connecting 115 Volts to it, then switch the motor first. Peradventure you ordered a 115V motor? Check the motor characterization earlier wiring, as putting 230 Volts into a 115 Volt motor can damage the windings, and probable impale the motor.
Replacing the motor (not the plastic wet finish, just the motor)
Having learned how to remove and break downwardly a pump and motor in the previous sections, replacing any of the components is but a matter of disassembling the pump down to the component that needs replacement, getting a replacement role, and reassembling the unit. Schematic parts images, or expanded diagrams found in our pump parts department, are very helpful in identifying individual pump parts.
Sometimes the motor will trip the excursion breaker when you endeavour to starting time it. If this happens it could mean there is something wrong with the motor however, information technology can also be loose wiring, bad wiring, or even a bad breaker, they do wear out, peculiarly if used ofttimes as the pump switch, or if the amperage rating is very close to the pump max load amp draw.
To replace a Threaded Shaft type of pool pump motor, here is the procedure:
Break down the pump by separating the volute or seal plate, and pull the motor back out of the pump. Shut off power and remove the wires from the back of the motor. Moving the capacitor out of the fashion, use a 7/sixteen" wrench to concur the motor shaft stationary, while you spin off the impeller in a counter clockwise direction. Use Channel type pliers to gently assist if needed or a strap wrench. With the impeller removed, remove the iv bolts that agree the motor onto the seal plate. Remove the seal plate and any collars connecting to motor to the seal plate. Remove the 'donut' seal half of the impeller that is pressed into the seal plate with a flat caput screwdriver. Make clean upward any grease or crude edges, and press the new donut into place, using a piece of paper to keep the ceramic seal face clean. Attach the pump seal plate to the new motor, tightening the four bolts snugly. Replace the spring half of the shaft seal onto the impeller, in the same orientation as removed. Attach impeller wear ring (pocket-sized side toward impeller) and diffuser over the impeller, if applicable. Wire upward the new motor (as described above), and reassemble the pump, making sure the seal plate o-band is in place. Tighten the clench band or bolts very tightly. Fill with water, supercede chapeau, open valves, restore power and fire it upwardly! To replace a Keyed Shaft motor (old brass pumps):
Suspension downwards the pump as described in the department on irresolute a seal. Remove the shaft extension by removing the Allen-Head set screws and pulling the extender off the motor shaft. Usually requires penetrating oil and some persuasion. Use your large apartment-blade screwdriver to pry the extender away from the motor trunk. Sometimes corrosion will swallow away at the setscrews and extender - if it is too tough to remove, replace information technology. Earlier sliding the shaft extender on the new motor, clean the motor shaft with a fine emery cloth. Apply a light coat of silicone lube to the shaft. When yous put the extender on the motor shaft, the setscrews go into a groove that runs along the shaft. Slide the shaft extender in place, lining upwards the set up screws along the channel, but do not tighten the set screws. When you have reassembled the subclass and seal plate, seal, and impeller, adjust the impeller to just barely clear the seal plate face, then tighten the gear up screws. Be sure the impeller is screwed tightly onto the shaft extender before making this aligning. Follow wiring instructions above, in previous section on installing new pumps. Bolt the motor bracket to the impeller housing, fill up with water and test briefly.
Pump Lubrication
A lot of air in the pump or loss of prime problems can be due to lack of lubrication on the pump lid o-ring. Lubricants like Magic Lube (Teflon based) or Jack'southward 327 Lube are e'er a great choice. Never utilise a petroleum based product (i.e. Vaseline) for lubrication on o-rings, which can impairment all types of pool o-ring rubber. Supercede pump o-rings if you encounter cracks, splits, or pinch marks, or if they become distended (enlarged) or flattened, or if they no longer make a practiced seal, despite efforts to reseat the gasket.
Replacing the Mechanical Shaft Seal
All pumps accept seals to prevent water from leaking out along the motor shaft. When these wear out due to salt or ozone damage, overheating, vibration or a sudden change in water pressure, resulting in a water hammer effect - you volition need to replace your pump shaft seal. For saltwater pools or pool that innovate ozone or chlorine in forepart of the pump, employ an Ozone/Salt pump seal, to resist damage to the seal.
The first matter to exercise is to turn off the electricity to the motor at the circuit billow.
To admission this seal for replacement, remove the bolts or clamp band that hold the pump halves together, (non the 4 bolts that concord the motor onto the seal plate). It is not necessary to remove the unabridged pump (wet end) from the plumbing system. Grasp the motor and pull information technology and the bracket or seal plate away from the pump volute. Y'all may need to jerk information technology slightly as you pull back to help separate the motor from the pump. Take a 7/16" wrench and hold the shaft at the rear, to prevent it from turning. You volition accept to loosen the capacitor (on the left) or the high limit (at the height), to gain admission to the back of the motor shaft, which is slotted to accept an open cease wrench. Unscrew the impeller from the shaft counter-clockwise, using large channel pliers or a strap wrench. Wrap a rag over the face up of the impeller to avoid harm. Remove the four bolts that agree the bracket or seal plate to the motor. If needed, use a hammer to gently tap a stuck bracket away from the motor. Remove both halves of the old seal. Notice how each half is installed so you get the new ane back in the same way. One half is on the back of the impeller and is easily popped off with a flat-blade screwdriver. The other half is pushed into the seal plate and motor bracket unit of measurement. Lay the subclass on your workbench with the seal on the lesser. Y'all will meet the back of the seal through the hole in the seal plate. Using the flat-bract screwdriver once once more, put the tip on the back of the seal and tap information technology with a hammer. It will pop out easily. Install the new seal. Clean out the seal plate and impeller where yous have just removed the old seal. Install each one-half of the seal the aforementioned way you removed the old one, white ceramic of one half facing the glazed carbon ridge of the other half. Utilize care in installing not to damage, nick or soil the face of either seal half. Paper Gaskets. When y'all break apart an old brass pump, the erstwhile gasket normally won't reseal. Clean the old gasket off of the seal plate and volute. Scrape it clean if needed with a flat blade screwdriver. Now reassemble the pump the same way yous took information technology apart, placing a new gasket betwixt the pump halves. Plastic pumps apply a rubber o-ring, which will almost always reseal again properly.
A fresh paper gasket might leak for a few minutes until it becomes wet and swells to fill all the gaps, but information technology should stop leaking after a brusk time. If your chore does leak, take it apart and go over each step once more, making sure the seal halves are seated all the fashion and that at that place is no corrosion or debris left in the impeller or seal plate that might prevent the new seal from seating completely. You may add some Blue RTV silicone sealant to help a paper gasket.
On plastic puddle pumps, the clamp or bolts are removed to detach the pump, and y'all volition usually discover a diffuser or impeller shroud roofing the impeller. After removing this, you can grip the impeller with your paw and twist it off, merely you'll need to cease the shaft from spinning equally you lot twist off the impeller. There are air vents in the motor on the end closest to the pump itself. Look in and you will see the motor shaft. Place a flat-blade screwdriver in one of the air vents and wedge it confronting the shaft to go along information technology from turning.
If the impeller won't twist off easily, and you don't desire to chance breaking the fan blades, you tin can remove the rear motor comprehend and look within as y'all twist the impeller. Y'all will see the back terminate of the shaft, with the centrifugal switch fastened (AO Smith motors). Since this switch is fragile, y'all must remove it (ane center screw) to access the slotted screw in the back terminate of the shaft. Place the screwdriver in this screw to go on the shaft from turning as you remove the impeller. Or utilize a seven/16" wrench on the back of the shaft, which is commonly slotted to accept an open finish wrench.
Instead of a gasket, plastic puddle pumps use an o-ring. Make clean this and lubricate it earlier reassembly. If information technology has stretched and it seems like there is as well much o-ring for the aqueduct in the volute, soak the gasket in ice water for a few minutes to brand information technology shrink. If that'due south not plenty, you tin can razor knife off a ¼" or so, and superglue the dry and straight ends. Pump Rebuild Kits include all of the seals, gasket and o-rings used on 22 of the near pop pool pumps.
Some pumps use a plastic impeller that holds the round seal one-half in place, instead of the leap one-half, like most pumps. If the pump has run dry and overheated, this impeller can warp or melt and the seal will non fit tightly. The only solution is to replace the impeller. This is a common problem with automatic cleaner pumps, which are non self-priming.
Remember to use only non-hardening silicone lube similar Magic Lube on all pool and spa o-rings and valves. Don't employ Vaseline or other lubricants that are made of petroleum, which eat abroad at rubber o-rings.
You may notice that the shaft seal has a larger inner diameter than the motor shaft. This is because the shaft seal doesn't actually touch the shaft. If it did, it would fire up in seconds, at 3450 RPM. The sealing is made not around the shaft, only betwixt the seal plate and the impeller, or between the ii seal halves.
Chock-full Pump Impeller?
When your pressure is high, your filter is dirty, right? When your force per unit area is lower than normal, notwithstanding, your pump basket is dirty. If the basket is clean, all the same pressure and flow is still low or surging, you may have an air trouble or the impeller may exist clogged. Something prior to the filter is obstructed. A clogged impeller volition still pump h2o, but only about half-speed. If yous have a clear pump lid, you will notice abnormally tedious swirling of the water, or the basket may non fill fully with h2o.
To unclog an impeller follow these steps:
Close off power, remove motor and seal plate from pump. Sometimes this is ane clamp that holds the motor to the pump, or some pumps have 6 bolts to remove. Stand motor on its end cap, remove whatsoever diffuser or impeller shroud, and using needle nose pliers or a sparse screwdriver, remove the clog. Run some heavy wire through the vanes of the impeller to ream out droppings, pushing it dorsum towards the eye of the impeller, where you can choice it out. Reassemble pump snugly and tightly. Fill pump pot with water and restart pump. Filter force per unit area so should rise to the normal range.
Replacement of a pool filter pump
When replacing your motor, you may opt to install a high efficiency pump (one that is sized correctly for your filter). This tin can reduce energy consumption and/or increment skimmer suction to make the puddle easier to proceed clean. As mentioned earlier, the best pump replacement is probable the same verbal pump every bit the one prescribed by the original builder, who nosotros presume did the correct calculations. Still, pool systems are dynamic, always changing with new equipment added or subtracted, and a previous owner may have installed a pump that is too large (or as well small, but probably besides large).
A great pick for many pools nowadays when faced with a pump replacement is to upgrade to a Variable Speed pump. They are uncomplicated to wire, include on-lath timer, controls, diagnostics and condition. VS pumps permit you lot to run the pump at dissimilar speeds, and save upward to lxx% on free energy bills. The tranquility running TEFC permanent magnet motor is absurd to the touch and is more durable than traditional motors.
The thought of a VS pump is that yous run the pump longer each day, perhaps xx hrs/day, only at low speeds, with 1 or 2 3-6 60 minutes loftier speed periods for heating, chlorinating and cleaning. Every bit mentioned in a higher place, IntelliFlo and EcoStar are loftier menstruation VS pumps for large pools with many features. Hayward and Pentair also produce several lower priced VS pumps built with mutual pump bodies, to retrofit to Maxepro, Superpump or Whisperflo pumps.

Supercede or rebuild your pump motor?
For most all rebuilds of a pump motor, expect charges of $130-$150 to have a motor shop rebuild a motor (new bearings and shaft seal, full examination). Some motor repair shops also offer drop off / pick upwardly service, in 2 days turnaround usually. Theoretically, the motor will concluding some other eight years, only the warranty may only be 90 days. The warranty on the new motor is 2 - 3 years for about manufacturers. Whether rebuilding or replacing the motor, the Shaft Seal should too exist replaced, or you can buy Pump Get-Kits, which include the Seal and all of the O-rings for a particular pool pump (typically includes the pump lid, diffuser, and seal plate o-rings).
If your motor is fairly new (less than five years old), it may be worthwhile to rebuild a motor with new bearings and a shaft seal. However, motors are much more than than just bearings and seals, and some other repair of a different sort may be just around the corner, for an older motor.
Above Ground Pool Pumps
Above ground swimming puddle pumps are designed for installation below water level, or what we telephone call flooded suction, and are not meant to lift water vertically.
Pool pumps are the 'heart' of the above ground puddle circulation system. And like your own beating heart, cardiac trouble is crusade for warning and immediate business organization.
That is why to a higher place footing puddle pump problems must be urgently addressed. With reduced flow rate, or a complete loss of circulation, your pool filter shuts down, and puddle chemicals become overwhelmed by a rapid build-upwardly of solids in the h2o.
How to Choose an Above Basis Pool Pump
Answer:
Match the pump output (in GPM) to your puddle filter design menses rate.
Above ground pool pumps take standard 1.5" threaded or union connections.
48Y Frame motors, 1/2hp to 2hp, for to a higher place footing pools from 3000 to 30000 gallons.
The best above basis pump is ofttimes an verbal model and hp replacement.
Don't install a bigger pump than your filter tin handle. If a new aboveground pump has no power string, you can reuse the pump cord with a new pump, as long as it's in good shape.**
How to Plumb an In a higher place Ground Pool Pump
Answer: For hoses, adhere one.5" polish hose fittings into pump with Teflon record.
Clamp skimmer hose from puddle to inlet port (in front of pump).

Re-use your pump hose fittings and power cord on new pump.
Install on a solid, elevated base of operations, below the puddle water level.
Wrap ane.5" hose fitting threads with iii-5 revolutions of Teflon tape (in a clockwise management) and thread into higher up ground pumps and filters, paw tight, plus ane turn only. Overtightening unions or adapters into pumps and filters can crusade stress cracks.
How to Clean an To a higher place Ground Pool Pump Basket
Answer:Shut off pump and close isolation valves on either side of the pump.
Remove threaded pump lids in a counter-clockwise direction.
Remove pump handbasket by pulling on handle or gripping on the within edges.
Bang out debris from basket, and replace into the pump.
Replace chapeau tightly, open the isolation valves and test pump.
Keep your pump lid operating smoothly and prevent air leaks by regularly cleaning with a soft rag and lubricating with a Teflon pool lube. Don't use Vaseline, which will eat the condom.
How to Wire an Above Ground Pool Pump
Reply:Shut off ability to the pump timeclock or switch, past flipping the circuit breaker.
Connect the bare copper bonding wire to the brass motor lug.
Remove the rear cover of the new above ground pump motor.
Remove the string connector from the sometime motor, and screw into the new motor.
Push the 3 wires of the ability cord through the connector and tighten.
Connect the green wire to the ground screw, and the other 2 wires to the large brass screws or spade terminals, labeled L1 and L2 (either wire).
To a higher place footing pool pumps but take 115V. Exercise not wire with 230V, they are meant to plug into a GFCI outlet with a grounded three-prong plug. Economize and schedule pump runs with a plug-in pump timer.
How to Prime an Above Ground Pool Pump
Answer:If beneath water level, a pump should be gravity fed and e'er full of water.
If in a higher place water level (not recommended), manual priming may exist required.
Close isolation valves on either side of pool pump.
Remove pump lid and make full basket and incoming hose with water.
Replace lid tightly, open valves and turn pump on.
If pump does not take hold of prime in sixty seconds, echo steps 3-v.
Be sure pump lid o-rings are clean and lubed with a Teflon pool lube. Seal whatsoever air leaks on the incoming hose or hose fitting with Teflon tape or other sealant. Cheque for blockage in the hose or impeller if pump priming problems continue.
How to Get to an Above Ground Pump Impeller
Respond:Shut isolation valves on either side of pool pump.
Remove the basics or screws on the front of the impeller housing or 'wet end'.
Slide the motor end dorsum, and out of the pump, separating into two.
Inspect impeller for clogs; vanes can be reamed with wire or a small rod.
Loosen bolts on rear of motor merely to remove the pump housing, or seal plate.
Remove the impeller only to replace the shaft seal or motor.
To remove an impeller, hold the motor shaft steady with a wrench on the slotted portion of the shaft, at the rear of the motor, backside the centrifugal switch.
Many impeller clogs can exist fixed by pulling out the pump handbasket and reaching into the eye of the impeller with a small-scale screwdriver or tool to patiently dislodge the bulk of the material, scooping it out by paw.
How to Replace an Above Ground Pump Shaft Seal
Answer:Use the correct mechanical shaft seal that fits your above ground pump.
Unplug pool pump, or otherwise cut all ability to pump.
Close isolation valves, and/or plug the skimmer and return lines.
Remove the nuts or screws on the front of the impeller housing or moisture end.
Slide the motor finish back, and out of the pump, separating into ii.
Concord the motor shaft steady with a wrench on the slotted shaft at the rear of the motor, so grip the impeller firmly and twist off, in a counter clockwise direction.
Pull the spring seal one-half from the impeller and dig out the circular ceramic part from the pump housing or seal plate, and supercede with new seal in the same orientation.
Tighten impeller back onto shaft, all the way until it stops turning.
With the sealing o-band in place, reconnect the pump housing together tightly.
Open isolation valves, turn power on and examination performance.
Pump shaft seals are ii pieces, the bound half and the ring one-half. The spring half has a hard plastic side that makes contact with the ceramic face of the band half.
In a higher place footing puddle pump issues volition happen, and you lot've got to be gear up to respond quickly to proceed your pool water filtered finer. If your puddle pump is unable to pump water, add actress chlorine to the puddle and brush daily to keep the water from turning green. You can hold a pool for i-2 weeks in this manner, depending on the outside daily temperature.

Booster Pumps
You may have an automatic puddle cleaner (Polaris) that requires a booster pump. It looks dissimilar from your filter pump because it doesn't take a strainer handbasket. This is because information technology'due south pumping strained and filtered water, and there should exist no debris to worry near. All else is the same as a regular pool pump; however information technology should terminal longer if information technology'southward being used but a few hours per solar day.
Never operate the booster pump without the filter operating and providing it a constant flow of h2o. If you have time clocks, synchronize them to ensure this doesn't happen. Otherwise, you will probably fire upwardly the shaft seal, and possibly damage the bearings, or demand to visit our booster pump motors page.
Blower Motors
If your puddle has an attached spa, y'all may have a forced air blower motor sticking up above water level. This is connected into the spa jets (render lines) to provide turbulence and air therapy.
If your blower motor is not working or is very noisy, information technology may demand rebuilding or replacing. Warranties and prices are very similar to filter motors. Before calling for service on any motor, check that switches on the motor are on, breakers are on, spa side or indoor remote controls are on, and the timer is on.
