Is it normal for a sand filter to blow sand out the returns when the pump starts up? I get four nice brown clouds every morning whent the pump starts up. I do keep the system backflushed.
I believe the sand filter itself could be 15+ years old, but no way to tell for sure, and no way to know if it's ever been refilled.
Also, at the top of the filter, should the clear dome have water percolating along with air, or should it be smooth, just water? I can get photos to illustrate what I mean if it would help.
