i am almost posative i blew the o ring on it while winterizing... my question is do i need to replace it? We are seasonal so we only use city water not fresh water from tank.Thank you
I removed the check valve parts from inside our city water inlet and enlarged the opening with a drill to provide better flow. Then I used a quality brass check valve with 1/2" thread on the interior side of the inlet (similar to photo). Threads right onto the inlet threads.
