I have a WFE-2 1/2 hp pump. I am wondering how much power does this pump consume ... it says its 1/2 hp so it should consume ~ 375 Watts? Can you please details its power consumption. Thanks

Is a 2 hp pump a ok replacement for a 1.5 hp pump? Both are whisper flo. I was told that it would not work because of sand filter issues. I find that hard to believe.

A     Answered on 8/12/2016 by Scott W.

I would need to know what model your sand filter is and the distance in feet from your pump to your main drain so that I can find your estimated flow rate and if your filter is able to handle the increased flow rate that you're wanting.

Hello. I have the pentair wfe-2 model and it was great but just stopped working. The line voltage is good and the capacitor tested good and the impeller is free spinning. Is there anything else that may have gone wrong or is the motor shot? If so can i purchase the motor separately ? Thank you

A     Answered on 8/20/2015 by Lennox H.

Hi, If the motor is getting power it sounds like the motor is shot. The 1/2 HP Standard Motor - Full Rate (B846) will be the correct replacement. I woull also recommend getting the Pentair/Purex Whisperflo Tune Up Kit.

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.

 (5 out of 5 stars)  This one is perfect

from Jacksonville, FL ()

Pros: It is so quiet ...

Cons: None !

I have to thank INYO for the quick response to my order. I was in desperate need of a new pump and their unbeilevable turn around time on my order saved the day. Thank you. Thank you. Thank you!!!!!! I feel fortunate to have found this site. The price was the best I could find. And their service was even better. Kudo's to INYO. You have my respect and my business going forward. This is a really good pump, I'm very happy with it ... it's so much quieter than our last pump. I have to look at the waterfall so I know that the pump is on.
