I am having my pool closed for the first time on Friday. The ladies at the pool store have advised me to have the water lowered to 4" below returns prior to my appointment. I have read that a DE filter should be backwashed prior to closing, yet when i am asked them they said no.
So what is correct? Is the pool guy going to show up and want to backwash my filter after i have already lowered level, thereby causing the level to be lowered more?
