So I'm losing water faster than evaporation. Found 1 small hole in the vinyl liner above the level of the skimmer (perhaps 1/2 a cm in diameter) which may be losing some water. Any suggestions about the best patch or putty to fill it in?
So I think most of my water is being lost behind the liner at a bad junction between the liner at the skimmer. It was previously caulked/puttied and this seems to be cracking a falling out. Any tips on the best silicone or waterproof filler? Eventually when I've put some more dollars away I imagine the skimmer will have to just be replaced (it's set into the concrete surrounding the pool), but I'm just trying to keep the pool going before closing and think it should be good through the winter. Water loss is about 5 inches in 48 hrs.
