I am a little late getting our 30' above ground closed up for the winter. This is only our second year doing it. I started draining the water level down with a small pump I used last year. Last night I unplugged the pump as we were getting close to the bottom of the return, with the intent on finishing up today. I left the pump and hose in however, and here the night and day the water siphoned down substantially (should have pulled the pump out). I am now left with about 12-18 inches of water in the pool.
The question is, do I need to fill the pull up to below the return for winter, or is it ok to just hold out and wait until spring? I don't want to do more damage, and obviously the air pillows are not going to do any good at this point. Thanks for the help.
