I have a JetVac cleaner with VS Whisperflow main pump and Pentair LA01N booster pump that tends to have trouble priming sometimes. If I understand correctly the main pump is always passing some water through the front intake of the booster pump, through the pump and out through the booster return line. Then when the booster pump kicks on it should run and drive higher volume through to the cleaner making it run.
All that said (assuming that's correct?), I disconnected the booster return line with the main pump off. Then turned on the main pump and had good water flow out the booster return, until the pump slowed down to normal speed. It has a feature where when it is first turned on it turns higher RPMs for a minute, then settles down to the programmed RPMs.
Once it "idled down", I had no flow coming out of the booster return line. Does that sound correct? Or should there always be some flow out the booster return?
Thanks,
GM
