Ok so I've ripped foam out of my tub where the water was and as I went in it's not leaking there. I pushed in with wooden dowels to see if I can find water, nadda. I don't want to rip out all my foam and it hit me, this tub sat without water for a year and the gaskets may have dried out. It leaks if the water is running or not and the PVC looks pristine. The leak is tiny like 1/4 inch of water per day.
So what are the chances that one or more of the gaskets around the suction inlets and / or the light lens is allowing water to leak. Can I use 100 percent silicone to seal it since there is no real pressure on these gaskets? I mean a tube is like $6 and a little time to do it right, but will it seal in a hot tub and hold.
