I just noticed today there is a thin "sheet" of water running down the wall of my pool from where the return fitting goes through. The gasket looks to have deteriorated from what I can see of it between the fitting and the pool wall. Doesn't seem to be bad now but will only get worse over time. What's the best course of action? Taking it out and replacing it would involve losing water down to skimmer level but that's not a lot. Would maybe trying to use some Permatex gasket sealer around the outside of the fitting serve as a temporary fix until swim season is over and I drop the water to skimmer/ return level anyway?
