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?

Answered on 02/16/2012 by 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.

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?

Why should I purchase a Tune Up Kit?

Answered on 01/12/2012 by 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.

Asked on 01/12/2012 by Guest

Why do I need to purchase a new shaft seal?

Answered on 01/12/2012 by 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.

What is Service Factor?

Answered on 01/11/2012 by 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.

   (5 out of 5 Stars) Pool Filter Motor

Reviewed By: from Bowie, Maryland ()

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.

   (5 out of 5 Stars) Perfect motor

Reviewed By: from Oak Hill, VA ()

Pros: Customer Service, Howto videos

Cons: None

I am not super handy but with the customer support and the how to videos I was able to successfully replace my pump and all gaskets. I saved over $400 for what the pool company wanted to charge. More importantly, I understand how it works now and can easily do it again next time.

   (5 out of 5 Stars) Perfect Fit - Very Quiet

Reviewed By: from Jacksonville , FL ()

Pros: direct replacement - very quiet. Not sure of savings yet.

Cons: Missing Lub/oil warning on Go-Kit.

Inyo's site is great and call help the best. Replaced an dead motor with the EE model and was pleased with how quiet it ran. I did miss the "don't touch the ceramic disks" warning on-line, I had even lubed it with the supplied grease in the go-kit!!! good thing I had went on-line half way through so I could clean the disks before any run-time. There should be a note included with the Go-Kit.

Shipping was Uber-quick -- 2 business days!

Got the product in timely fashion. Relatively easy to install and works well. It is quieter than the original and seems to pump more volume of water. Very happy with it.
