This is the end of the first summer since our pool was installed last fall. Once the build was complete last year, the builder covered the pool and winterized the main drain. He didn't cut the hole in the liner for the returns and skimmer until opening this year so there wasn't any water in the lines last winter.
I've read that some people let the water level drop below the return lines and some people don't. Are the any specific reasons to drop below returns? Any reasons not to drop the level below the returns? My pool info is below, I'm mainly worried that if I lower the water below the returns, I'm concerned about the liner possibly shifting. Am I over reacting? For the liner to shift would the water need to drop significantly lower than the return?
