My water's crystal clear, but I'm getting seeing sand on the liner.
I replaced the laterals last year when we got the pool up and running.
While the pump is running sand is not coming out of the filter, this was verified with a sock over the return.
I shut the pump off last night around 7, no sand on the bottom as it was freshly vacuumed out. This morning around 7, no sand whatsoever. I go to work and come home at lunch, sand on the boom, pump wasnt on.
I haven't had the multivalve removed or apart since last Spring. Could this be a spider gasket issue? What other reasons could this be?
Note that while the pump is running, the valve does leak out a fairly steady drop out the waste port.....
