A puzzler me, I have an air leak on one side of the 3 port Dial A Flo supply side valve. I've isolated it to that location by pouring water on one side and watch the bubbles diminish in the pump skimmer. The 2 return lines come straight up from the ground, go into 90 degree threaded fittings that are threaded into the valve. I tried twisting the valve one direction to see if I could free it from one side but that doesn't go far enough to disengage the threads. I tried doing this and building up the Teflon plumbing tape on each side but it doesn't seem to then make a lot of sense to drive it hard to one side, then loosen it up. I guess when they built the pool they must have put the fittings on the valve, then glued the fittings to the supply pipes. I tried to RTV Silicone (what is in red) but still haven't fully sealed it. Any thoughts on the best way to tackle this?
