hello, i am looking at the posts about winterizing the above ground pools. my question is, is it ok to drain the pool? along wiht all the other pertinent pump and hose things to do? it makes sense to me to drain it so as not to have to be concerned about water quality over the winter and the pool is only 4500 gallons? btw i do plan to put the cover on after draining, should that be recommended.. btw it does not snow here , nor barely ever dip below freezing . appreciate the support!
