I have an old side drain near the bottom that is leaking (it is no longer in use). I tried putting a vinyl patch around it, but because it sticks out, it didn't seal well and only slightly slowed down the leak. What else can I do to stop it?
I can't get a good picture but it is exactly the same as the return jet, just with a small grille that screws in instead of a jet fitting. I replaced the grille with a cap, so the leak must be where it passes through the liner.
