Re: safe depth to drain vinyl pool w/vinyl stairs
Actually a complete drain using a plastic sheet to form a membrane between the old and the new water is not diluting water. It is replacing it. Your suggested method is diluting it. I don't know if this is an important distinction
It had occured to me to drain a little at a time, gradually diluting the CYA content, but total draining seems so much more direct.
Which is most efficient, less trouble, less money, and less time? Would the dilution method require more water or less to get the desired results (water is really, really expensive where I live)? The answers may be obvious to some, but not to me. Maybe I'll crunch a few numbers and try to figure that last question out.
