    No/low pressure on filter

    Help?!?!

    I fired up the pump/filter for the first time this season and I'm getting no or very low pressure on the filter's gauge.
    I let all the air bleed out so it's a constant stream of water. The return seems to have good water pressure coming out of it back into the pool. Nothing seems to be leaking. I let it run 2-3 minutes and then turned it off so nothing would get ruined...

    Any ideas why I'm not getting a pressure reading?

    Your pressure gauge is probably broken. Those gauges break easily. Fortunately, they aren't very expensive to replace.

    The filter is less than one year old - do the gauges go bad that quickly? Is there any way to test the gauge itself?

    The only other thing different from last year is we installed a new heat pump, but as I said - the return pressure seams normal (like before the heat pump was in place)...

    Thanks!

    I've never had a gauge survive a winter outdoors. They are cheap junk.

    We stored the filter/pump in the garage for the winter (Michigan) - do you think the gauge is bad? Any way to test?
