Hi All,
We got a brand new pool surface (Marquis) and a brand new DE filter yesterday, a big one 60 is the size for my 20,000 gallon in ground pool with chlorine and a pop-up floor system.
It runs nicely at a pressure of 18 or 20 but then after about 2 hours pressure climbs to 34, water from waterfall slows to a trickle and pop-ups stop working. They told me to backwash it so I did and pressure goes back down, everything works and then in about another two hours, same thing.
I don't have a lot of confidence that they know what is wrong.....can anyone help?
