    Polaris Booster Pump Loses Prime/Pressure

    The booster pump starts out strong and the Polaris works fine, but after a couple of minutes, the sound of the pump changes (due to water no longer passing thru the pump, I assume), the outflow hose gets soft (no water passing) and the Polaris basically dies (usually in the deep end, not sure if that is significant). I have hooked up a couple of different crawlers and the same thing happens, so it's not a Polaris malfunction. This just started happening and is a change, it used to work just fine. I don't see any obvious leaks at the booster pump. Any suggestions? Thx.

    Welcome to TFP!!!

    Is your main pump running at the time this happens?

    Yes, main pump is always running and I do not notice a change in its activities when the booster pump loses water pressure. Thx

    Odd. Sounds like a blockage is occurring either on the suction side or in the impeller.

    I'm a "try the easiest possibility first" kinda guy. Which would be easier to check for blockage? Where would I check for suction specific to the booster? I can take the pump apart and check for issues, but I assume the suction check would be an easier first step? Thx.

    I assume the suction line attaches to the main plumbing after the filter. So that is hard to inspect. You could try pulling the hose off the front of the booster pump and turn the main pump on and see that you are getting a lot of flow out of the hose. Then pull the pump apart and check the impeller.

    Great! I would suspect a busted impeller shaft if there was no movement at all, but that 3 minutes of up time perplexes me. I'll take a look at it and let you know what I find. Thx.
