i repaired an olympic size pool of 50 feet by 84 feet by 4 feet deep. 34,500 gallons . pipe size 4 inches from Main Drains and Skimmers to pumps. Can a 3H.P: or two work to circulate the water ? Please respond as soon as possible as pool is full of water and needs to filter.

What is the distance from you main drains and skimmers to your pump so I can calculate the flow rate?

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.

Pros: Quiet - Reliable

Cons: They really don't "sip" electricity despite being "efficient."

The pump arrived well packaged. It was an exact replacement for an existing pump that failed after about 5 years of service. The pump was the proper model and horsepower. The pump worked. It seems to me, subjectively, because I did not utilize a decibel meter that this pump makes slightly more noise than the last. However, in the larger realm, these Whisper Flow pumps are much quieter than others I have utilized.
