Hello from Oklahoma City! This is sort of a two part issue but deals mainly with closing. We are coming up on the end of our third summer with our IG (Liner) pool. For the past two winters, we have left our pool open. The Auto Pilot does an excellent job of making sure the pump runs when the water gets too cold although I am a little paranoid about a possible ice storm that might knock out our power for an extended period of time. Sorry for ramblingâ€¦here is my question(s): We do not have a cover and donâ€™t really want to spend big $$$ on one. Is it OK to winterize without a cover? Do I need to do anything special over the winter? We have no leaves to worry about although I am sure with our wind, there will be plenty of dirt and construction trash. We are also grappling with a small â€œvery annoying:â€ leak. Spent yesterday afternoon in a very cool pool and was not able to locate anything obvious with the liner although scuba would be a much better alternative to my limited lung capacity. I was thinking that closing the pool would eliminate the plumbing as a possible source for the leak. If the plumbing is taken out of the equation and we continue to lose water over the winter, then maybe the liner is our culprit. Would appreciate any input from the groupâ€¦thanks in advance!!!!
