I am new so please bare with...
On the 30th, I am having the pool company coming to help me close, but I want to make sure "we" do everything right. I am going to drop water level to 4" below returns and make sure water chemistry is good. Then i will blow out lines. Not sure if they will have me use antifreeze or not?
Can someone look at my system and give advice on how to close this properly? Also do i need to backwash the filter before closing? How do i know that there is NO water left in filter? Thanks.
