I just replaced the existing Waterway multi-port valve on a Millennium 27" sand filter with the same Waterway MPV. The valve immediately began leaking under the gasket where the threaded sleeve meets the manifold. Thinking it was a 'lemon', I returned it immediately and replaced it with the same Waterway MPV. It worked for about a week, and then began leaking again at the same spot. I have tried everything from the marine lube to the rubber mallet tightening technique. I've backwashed the filter many times with the same results. When I spoke to Waterway, they said the threads on the sand filter manifold may have been damaged. I looked and cannot see any visible damage. Does anyone have a similar situation and a solution? Thank you.

How does the gasket look? No damage, right? You lubed the gasket?
Some folks have found that turning the flange a quarter turn has helped (no explanation why but worth a try!) Also check to make sure its not the flange itself that has a crack.
Let us know what fixes the issue, ok?

Hi Maddie,
Thanks for the response. I did lube the gasket and the flange does not appear to have a crack. The only thing that seems a bit odd to me is that gasket looks to be a bit to large. It is the gasket that came with the new valve, so I can't imagine its wrong. I am going to request a new one to see if that works. Otherwise, I am left scratching my head again.
