    Low speed pump=Filter 0

    The electrician was here sometime today and got my pump wired so I could use the low speed. I don't think he could figure out how to wire it in to the Pro Logic the first time When I put it on low my filter pressure gage goes to 0. Is that normal?? I can hear water gurgling in the filter. It seems it's just one thing after another


    Thanks

    Pressure should be about 1/4 of high speed but the gauge may lose accuracy at low pressure so it may look like 0 but actually be a few PSI.

    With the pump on low speed the filter pressure can be zero, or one or two, something quite low in any case. You should be able to feel flow at the returns.

    Yes, I have quite good flow at the returns, so is everything o.k.
