I'm still a newbie and learning but this doesn't make a whole lot of sense to me?
I live in Southwestern Arizona so freezing is not an issue. My buddy and I were talking this morning and he says he plans on draining his pool next weekend. When I asked why he said to "replace" the water?
I have never heard of this but he says that you are supposed to do this every year? Because the pool water gets contaminated with minerals and other biproducts of chlorine?
Is this accurate?
