    Backwash valve o rings

    My pool is leaking through the Pentair 2" backwash valve. I am replacing the o rings in the valve. Found a "You Tube" video that's pretty self explanatory. Only question is do I need to entirely drain the filter before removing the piston shaft of the backwash valve?

    Welcome to TFP!!!

    Please add your pool details to your signature as described HERE as it will help us help you.

    Any water in the filter above the pipes to the backwash valve will need to be drained or it will come out when you remove the shaft.
