Help, I have a leak on my Hayward S1700 sand filter. It is the o-ring on the multi port valve part # GM600F which I just replaced and it is still leaking about 1 drop every 1-1/2 seconds. Like I said, I replaced the o-ring and it still leaked, so I removed it again, wiped everything dry and coated the filter body with KY Jelly hopeful to make a seal. Well, it didn't work and it still leaks at the same rate.
I was wondering if I should get something like a gasket seal compound from an auto store. What do I do? The old ring was intack and looks as good as the new one.
