Hello This should not happen! The old eyeball and trim ring was lost and could not be installed this year. So I went to the local pool supply and purchased a new good quality PoolMaster wall Return fitting and installed it. Well I could not get it to stop leaking! It was not leaking where it touched the pool wall so I know it was installed properly! It was leaking where the inside house adapter screws into the fitting that is attached to the pool! So I went back to the pool store and they said to put Teflon tape on the inside fitting. I asked where does it say in the new package that this needed to be done and did not get an answer because it does not say anywhere! So I bought some tape and put it on. Not too much and not to little! Well if the pipes were tapered, then this would probably have worked! However it did not! So I had some TFE plaster or plumbers Teflon Pipe thread paste and put that on. It does not harden so the pipes can be removed but of course in this case there is never a need to take these apart! Again that was better getting the leak from squirting out down to a slow dribble and would have worked if the pipes were tapered! There is about 20 PSI of pressure here and the Teflon Paste bottle states it does not hold the pressure especially if the pipes are not tapered! I am not the only one having this problem! See https://www.troublefreepool.com/threads/18672-Small-Leak-on-return-on-outside-pool-wall Home Depot has a new pipe dope called MegaLoc so I came home and gave that a shot. Where Teflon Pipe dope is white this is a light bluish green or aqua color and it worked! I also though PVC cement may work fine too. Then there is one last problem! The new wall or filter return should come with a 3rd gasket made out of a different material usually cork, see last pic below. This gasket goes on the outside over the wall return gasket so when the return fixture is tightened down on the pool, it stops the rubber type seal gasket from twisting and stretching! My new wall return did not come with this 3rd gasket so I had to make one out of a red silicone sheet. This worked well as you can see the cream color rubber gasket is even and not stretched out at approx 11 o’clock as in the pevious Pics! What would you do? Have you seen this problem? Pic 1&2 - shows a spray coming out and water dribbling down Pic 3 - fitting with MegaLoc Pic 4 - MegaLoc Pic 5-7 Where does it say how to stop it from leaking? Pic 8 - new red silicone holding gasket Pic 9 - Silicone sheet Pic 10 - The missing 3rd gasket for my new part. Looks like cardboard but a little stronger and more flexible, it is cork! However the high temp shinny silicone gasket I cut may last longer and it works great!
