I'm in Texas and am relying on the freeze protection feature to prevent pipe freezing. It seems to be working by starting the pumps during cold weather. However, the each morning after a cold night, I've noticed that the pool water level has dropped several inches. When the weather is warm the level does not drop and haven't had any other issues. No standing water around equipment to indicate anything is leaking.
Any ideas here? I've done some searching, but haven't run across anyone reporting the specific problem.
