I have a leak. It is on the suction side of my sand filter. It appears to be leaking around the threads. Last year I stored it in my basement. I have disconnected the pipe and switched the connection and it still is leaking in the same spot. The gasket looks fine. I'm not sure if I missed something simple. Any thoughts?
