Hey guys, my Hayward MPV Variflo XL is leaking at the base where it connects to the sand filter. It is a top mount. Started leaking gradually a few months ago. Tightened the screws a little and we were fine. Now it is a constant flow from the seam area on the sand filter.
I have taken off the MPV and replaced the O-ring and changed the sand while I was in there. This unit is only 1-1.5 years old. Tightened everything back down. No difference. Still leaking. Talked to my pool shop. Suggested pinched O-ring or possible crack in the clamps that hold the MPV to the filter base. I purchased new clamps and tried them. Also, no pinched O-ring that I could see. Reseated everything. Started up. No change.
Read a post on here from 2009 that had the same problem. Suggested loosening the screws and see what happens. Tried it. Now more leaks. Tightened screws gradually with pump running and leaks (multiple now) will not subside.
I did find seams on the MPV that could be the culprit. When the plastic was molded, the seams are very large in my opinion. I took my dremel and lightly sanded the seams down. Thought that might be the issue. Nothing changed.
I am considering caulking the fitting and then dealing with that whenever I need to get back in. Anybody have any suggestions before I caulk this #$$%%^&(^&$%#!
