Thread: Loss of pressure

    Loss of pressure

    Hello.

    I have a Polaris Caretaker system with the 5 port valves. Recently, when I turn on the pump it starts to push water into the "pre filter" just before the pump, but it never fully pressurizes. Then, after a minute or two, all of the water will suck out of the "pre-filter" basket housing and then this cycle starts again. Due to this "phenomenon", my pop ups never engage. I see no signs of leaks.

    I'm wondering if it sounds like the pressure relief valve is bad? What are typical signs of the pressure relief valve going bad? Any other ideas would be greatly appreciated. Thanks.

    Seems like I have an air leak, and it's intermittent. The pump was working fine last night.

    Can anyone tell me anything about the pressure relief valve?

    What is the pressure at the filter and the pressure at the valve?
