Sitting here after 18 days in a row over 100 degrees and with no end in sight, I'm dreaming of colder weather and got to thinking about what would happen if we ever did get below freezing here again. Can the liquidator freeze over in the winter? I don't close my pool, as we use it year round. When the temp drops low enough, the freeze guard kicks on and circulates everything. Would this be enough to keep it from freezing? Or do I have to drain it during cold weather?
