This problem started last year, when I noticed that every time I turned the pump on, a small amount of sand would blow out of the returns then stop after 3-5 seconds. Because of this, I did some research on here and the most common suggestion was to replace the laterals because one was probably cracked. So last year, I replaced all 8 laterals and the hub, but noticed none of them were cracked. I also replaced the multi-function valve gasket in case sand was somehow getting past that. While I was in there, I also replaced all the sand. Nothing changed but it was livable so I just left it as is.
Fast forward to this year, and it's getting worse. The pool constantly has a thin layer of sand on the bottom and it looks terrible. Also, when I backwash, a lot of sand comes out of the hose. There's a pile of sand at the bottom of my driveway from backwashing. What else could be causing this?
