I have seen pictures of pools with all filtering systems,pump motors,sand filter tanks and all pvc pipes, exposed to the weather,or uncovered. If it is ok to let all systems be uncovered will someone please tell me. It seems that the elements will damage all these things. I really don't know. These things cost so much money,but if it is unnecessary to cover them then I won't bother with it. I sure do thank you if I can get any answer. THANKS.
