Last year I don't think we drained it low enough and we had a freezing rain and freezing temperature problem where ice backed up into the skimmer and ruined the pool wall. Admittedly, I don't think my husband was all that careful about checking the water levels through the winter, either. I guess he figured after 10 years with no problems he must have been doing something right. 10 years of mild winters, though, lol.

Needless to say, after replacing the pool, I want to be extra cautious this year. My new pool is a 21' round Aqua Leader with all resin components. Aqua Leader recommends draining it 18" below the skimmer opening. Other literature I've read says 6".

Is it just me, or does 18" seem like a lot?

Anyway, I'm curious what most of you do.
