With winter coming I'm looking to storage options for the heater, pump and sand filter once again. I normally store these inside in the heated garage which I COULD do again but I read the Pool School "Closing AGP" article and it got me wondering if I can actually store these things (adequately dried out) in the shed out back? The biggest question is the sand filter - will it drain out enough to be dry enough in a month or so to not have to worry about it freezing and splitting?
