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.

Pump motor froze up with my Pentair Whisperflo

Written on 8/2/2023 by Guest

Basically followed Inyo’s you tube video. The hardest part was disconnecting the 5 year old motor from the pump assembly. Once apart the replacement was extremely straightforward. Be sure to keep all the spare screws and parts so you don’t loose them in the grass. The other point to keep in mind is to know which switch controlled the power to the motor. My unit provided the bubbles to my spa. Once I had it all together (took maybe 10-15 minutes) I turned on the “Bubblers” switch. It didn’t work so I took it all apart to make sure I didn’t install it to cause it to bind. Turned out the power to the motor was turned on from the “Booster Pump” switch. Silly mistake on my part. Once I figured it out and got it back together it all worked well.

My filter pump motor on my saltwater pool went out.

Written on 9/17/2019 by Guest

I searched for a replacement motor and few sites gave the replacement model numbers for the replacement motors they carried. INYO pools provided the exact model number matching the A O Smith motor they inventoried.

I simply placed the order and had it at my doorstep in a couple days. I am impressed with the prompt service. Having your filter pump out in the peak of summer in Southern Louisiana can wreck havoc on a saltwater pool. However, INYO Pools was prompt and I was able to quickly replace the motor with the necessary replacement O-ring kit.

A note on replacing the pump shaft seals; to remove the old seal, I used a 3/4" PVC collar to tap out the seal and a 1" PVC collar to seat the seal. It worked perfectly.
