Just opened my pool and the water is looking pretty good, but the filter seems to be a problem. When I vacuum over a dirty section, the dirt is discharged almost immediately from the returns back into the pool. Have a Hayward 210T sand filter. I replaced the spider gasket last year but not much else has been done. Any ideas on where to start looking for the problem? Thanks.
