    PSI gauge

    Just moved into home with 24ft x 4ft pool with sand filter trying to get it up and going but the pressure gauge is still at zero when the filter is turned on any ideas of what I need to do?

    Hi, welcome to TFP! The pressure gauge is easy to replace. You can get a replacement gauge at most hardware stores for less than $20. The gauge will unscrew from the filter and you can take it with you to be sure to get the correct size.

    Gauges are cheap and very expendable.

    Maybe you have some valves that are closed or something.
    Post some pictures or at least a more detailed description of your plumbing. How did you "turn the filter on" ?

    Do you have water flow coming out of the return jet?

    Re: PSI gauge

    If it had a rubber plug with a little rubber tip/nib did you follow the instructions to vent interior air space? Did you use 2-3 wraps of Teflon tape? Pictures please. Does the pump prime successfully? Is the manual air vent open/closed

    Re: PSI gauge

    Two speed pump on low? I have a two speed 1 hp pump, and the psi gauge stays at zero when it runs on low speed.

    Re: PSI gauge

    That is true if you have a two speed or variable speed pump and run it on low speeds the gauge may not show an increase in pressure. If that is the case set the pump to a higher speed and see if the gauge moves.
