First off, many thanks to all who helped my with my shock process last month. Since about the first week in September, I've been crystal clear. Working to get my TA down, will post some question in it and scaling, but first my valve issue.
I am getting a progressively worse leak out of the waste port on a Hayward Vari-Flo valve, SP715XR50. Can the valve seat gasket be successfully replaced on these? I've heard both sides locally, but thought that I would open the question up to a broader audience.
Any advice will be appreciated.
