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 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.

I am replacing my pump and it's currently got 1.5" piping. Is there a way I can get this pump (with the 2" piping) to work with it?

A  Answered on 6/3/2012 by InyoPools Product Specialist Patrick P.

This pump is only available in 2" ports however If you have 1.5" pipe it is not a problem to go up to the 2" ports on this pump and this can be accomplished by the purchase of two standard pipe fittings which can be purchased at your local hardware store. The problem would occur if you had 2" pipe reducing down to 1.5" ports as this causes a bottleneck, however going from 1.5" pipe up to 2" ports does not cause any issues.

Can you help me find replacement seals for this Pentair Whisperflo pump?

We have 2 different tune-up kits for the Pentair Whisperflo. The first one is for a standard pools and the second one is for saltwater pools. The saltwater tune-up kit comes with a heavy duty shaft seal and can be used on all Pentair Whisperflo pumps.

Is Up Rated ok or is Full Rated better? Would a energy efficient 1 horse power Full Rate be better than a 1.5 horse power Up Rated?? 520-241-4692

A  Answered on 12/4/2014 by InyoPools Product Specialist Brian M.

Hello  Eddie. We get this question a lot. Full and Up Rated motors were the industries first attempt at making motors more efficient. This was before 2 speed and variable speed arrived.  This is a link to and explanation of How To Understand True Pump Horsepower - Up Rated vs Full Rated. I believe it will answer all of your questions.
