A     Answered on 5/30/2016 by Alex V.

Neal, Are you referring to parts for the pump or parts for the motor?

?     Asked on 2/29/2016 by James

Do gaskets come with the pump or must I order them separately ?

A     Answered on 3/1/2016 by Lennox H.

Hi James, Gaskets for the pump does not come with the motor, you will have to purchase them separately. You will also have to know the manufacture and model of the pump housing that the motor connects to in order to locate the correct pump gaskets, o-rings and shaft seal.

?     Asked on 2/18/2016 by Lynn

I have the A.O. Smith Motor 7-193995-07, which all the specs are the same on the motor that I am looking at, but my motor has --- HP instead of saying what the HP is. The Jandy Stealth pool pump says 2.5 hp. Does this motor work with my pool pump, as it is a 2.0 HP motor?

A     Answered on 2/18/2016 by Lennox H.

Hi Lynn, This B843 motor will be the correct replacement motor for p/n 7-193995-07 that is mounted to your Jandy Stealth pump. This is a "full rate" motor, what that means is the it's rated a 2 HP but has a service factor of 1.3. When you multiply the rated hp by the service factor you get the total hp of that motor, which would be 2.6 HP.

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?

A     Answered on 2/16/2012 by 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?

A     Answered on 1/19/2012 by 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.

Why should I purchase a Tune Up Kit?

A     Answered on 1/12/2012 by 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 1/12/2012 by Guest

Why do I need to purchase a new shaft seal?

A     Answered on 1/12/2012 by 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?

A     Answered on 1/11/2012 by 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

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

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

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!
