What is Service Factor?
 Reply

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

Why do I need to purchase a new shaft seal?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

Why should I purchase a Tune Up Kit?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?
 Reply

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?
 Reply

A  Answered on 2/16/2012 by InyoPools Product Specialist Patrick P.

Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.

Bad pump on pool opening

Written on 4/21/2023 by Guest

I was discouraged after being told our pump was not working while trying to open the pool for the season. I was told a replacement would be $700.00 plus. I search the internet and found it here at INYOPools for less than $400. I watched a few videos on pump replacement and decided to take it on. I made sure the electric was off and no longer hot from the panel. There were two sets of bolts, one for the pump to the impeller housing and one set for the housing to the filter housing. I used a 9/16th inch socket to remove the bolts holding the housing to the filter housing. Once this was removed, it was easier to remove the bolts holding the pump to the impeller housing, with the same 9/16th inch socket. Once both were free and separated, I used a straight screwdriver to remove the screw holding the impeller on the motor, while holding the bolt on the back of the motor still with an adjustable wrench. Once this was apart, I had access to the pump seals, which were easily pulled off. I was able to replace the lower seal with the new part, but the upper seal was still in great shape and I left it on. Once I was ready to reassemble, the steps were very easy in reverse. The only addition was using a vasoline around the edges of the gaskets that were around the impeller as well as around the housing that connected to the filter housing. This just allowed a better seal in hopes that I would not have to replace the gasket. I had a 240V connection, so both black wires were connected and then the ground. I also had a bonding wire that connected to the back of the motor as well. Once these connections were made, I cleaned up everything around the motor and turned the power back on. I was excited to hear the motor come on and then after priming the pump to see all of the outlets start moving water. It took about 1 hour and was super easy to do.

Frozen pool motor

Written on 5/29/2022 by Guest

Long story short, the house we bought had a noisy bearing. I mean LOUD. Our neighbors complained. Overwinter, it seized. Upon recognizing the equipment failure, I ordered these parts intending to replace the bearing and seals, but instead procrastinated and lost these when the time came. Ordering more, will review when complete 👍🏻

Old motor bearings worn and noisy

Written on 10/29/2020 by Guest

I first turned off all power to the pool equipment. Then I disassembled the challenger pump and the electrical connections to the motor. This allowed me to take the motor with pump backing plate and impeller to my workbench for further disassembly.

Don’t forget the screw holding the impeller to the motor shaft is turned clockwise to loosen. A strap wrench makes impeller removal easy turning it counterclockwise to remove from the motor shaft. The hardest part was loosening the bolts holding the old motor to the pump backing plate. An impact wrench was required but after copious lubrication I got them off. I cleaned the bolts with a wire brush before reassembly. Then replaced the backing plate portion of the seal and bolted on the new motor.

Then reassembled the pump backing plate and motor with new O-rings and the impeller side of the new seal. Went back outside to complete the pump reassembly and connected the electrical. Primed the pump and turned electrical power back on and started it up! Success. No more noisy pump motor.

Old motor burned up

Written on 5/26/2020 by Guest

1. Ensure power is cut off to unit at both panels
2. Disconnect power lead to old motor
3. Remove bolts that connect back plate with motor still attached and pull from the pump housing
4. Once these bolts are removed you can lift the entire unit (motor and back plate) out and then disassemble motor (4 bolts I think) from motor to back plate.
5. Remove the diffuser which allows access to impeller and remove 1 stainless steel bolt in center
6. Now you can remove the impeller that will allow access to motor mechanical shaft seal 7) With back place off and impeller removed replace new seals and reverse order

Existing pool mator seized up and needed to be replaced

Written on 4/12/2018 by Guest

I removed the old pool motor, housing, and impeller. I matched the specifications of existing motor and ordered a new one from INYO pools. After receiving, I went to a local pool store to buy the shaft seal as I forgot to order. Once I had that, wired everything back up, attached back to my filter and flipped on the power. Worked perfectly.
