Question about Pentair 1.0 Hp Whisperflo Pump

1 Answer

Pool pump won't prime

I have a New pentair whisperflo, about 1yr. old. Been working great. Today I was vacuuming a few leaves off the bottom of the pool and the vac line suddenly jumped and the suction went away. The leaf filter was packed when I emptied it. Now the pump won't prime. A little water is being pulled through at the skimmer basket and the pool is full. Air bubbles are coming out the return and the pump is pulling some water through at the leaf filter but just won't really get going. Any ideas where to start? I'm about to clean the filter and inspect things internally.
Thanks, Jim

Check for air leaks, cover o-ring is common culprit. anything in front of pump can cause this.

Pentair WhisperFlo 1hp, 230v, Dual Speed won't start in morning


If the high speed side of a two speed pump will not operate it is because there is a problem with the windings on the high side of the motor.
You will need to either take it to a motor shop and have them fix it or replace the complete motor.

Pool won't hold prime. I cleaned the filter & basket. Prime is slow to come up but then surges up and immediately drops back down.

When I turn on filter the pump makes a loud noise, then kicks on but runs loud.


these are known to have rear end bell issues , the motor will need service by your local pool pump motor repair guy. cost about 75.00 .. if you keep running it it will destroy the motor and a new motor will be your only choice .Leave feedback for your favorite fixya guy.. that would be me the pool pump motor repair guy in longwood Florida.. don't forget to prime your pump after a repair !!

3/4 Whisperflo will not prime


once you figure out why it's having trouble priming, you can reduce the discharge side with a valve to adjust the flow to what you need. You can always always reduce the discharge side but never the suction side.

Pool pump won't prime. Impeller replaced, worked for a couple of days. I changed the filter now same as original problem won't prime. I thought perhaps it was clogged; however since it was running and...


sounds like a priming problem. look at the check valve in front of the pump in the suction line. sounds as if it is loosing its prime so you don't have enough water close enough to the pump to get it primed.
