My pool is in desperate need of draining, however, it's 100 degrees daily and will only get hotter. Researching this site, I came upon a few posts that recommended draining and refilling simultaneously to ward off potential plaster cracking. There are two schools of thought:
The pool water is warmer than the tap water, therefore pump out from the top, refill from the bottom
The pool water is heavier than the tap water, therefore pump out from the bottom, refill from the top
Does anyone have first hand experience with this?
