Sand entering the pool

[shanemcg83]

Hello. I have sand entering my pool. I placed a duda filter bag over the return and saw sand. What is the possible cause of this? Any help would greatly be appreciated

Things worth mentioning; sand filter is 18 in, pump is 1.5hp, filter not level.

Could the pump be too powerful and blasting sand into the pool?
Would unlevel filter be an issue with sand entering the pool?

If it has always done this, possibly. If it never did it before, then it's probably something else. As for being level, it shold be. There is a small variance if a pad shifts a bit, but if it's really obvious and out of level, it should be addressed.

Other than that, sand entering the pool can be associated with:
- broken/loose lateral
- Bad center standpipe or hub connection at bottom
- Poor quality sand or incorrect size (#20 silica)
- Multiport valve (spider gasket/key diverter assy).
- Not rinsing long enough after a backwash.
