I just purchased one for my pool closing this yr. I was thinking of plugging the skimmer (the opening inside wall of pool) and raising the water level. I have a solid cover and the water accumulates on top and puts a lot of stress on the cover. I know most people use pumps but I thought by rising the water level less can accumulate on top.
I have one way valves to plug the returns so I don't have to drain below returns.
Has anyone done this? Any experience with this type of plug?
