What is Service Factor?
Reply
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
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 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?

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
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.

So far super - Purchase the correct gaskets, check the purchased "GOKIT" contents. Buy as an extra salt shaft seal & install a new threaded impellor. Learned I need to change the shaft seal regular prior to failure and if the pool is salt get the correct one!

(5 out of 5 stars) Excellent Motor
Reviewed By: Navspecwarops from Roseville, CA ()
Pros: Very quiet, direct replacement, improved efficiency
Cons: Took ten days to arrive.
I purchased this motor after an email dialog with INYO's customer support and reviewing their PDF installation instructions. They also recommnended the gasket kit as I was changing out an original motor about ten years old. This was my first foray into pool equipment replacement but the whole process took about four hours. The biggest hang up was trying to remove the impeller and its rusted flat pan screw. I ended up drilling it out.(How about including one in the gasket kit?) With my new experiece I'm sure I could do it in under three hours the next time. The new motor runs amazingly quiet and its often hard to tell it's on from a few feet away. My only mitigating complaint is that I ordered it on a Wednesday morning and did not receive it until Friday, a week later. I ordered the motor as mine was getting loud and it eventually failed five days before delivery. Overall, the process was quite satisfactory.

This is the same motor as my original one, which worked well till the bearings worn out and started making loud noise. This motor is quiet and powerful yet pretty small.

Pros: Customer service, shipping time, price and product
Cons: None that I can think of
Best of all is the wonderful customer service help provided by Inyopools. The product was here in the time specified and the price was considerably less than the 5 other companies I checked with first. The product was as specified and ordered and hasn't given me any problems to date. It was installed about a month ago.
