DE seeping through pump while off

Postby meanirene100 » Mon 23 May, 2005 19:38

i have been experiencing an unusual problem. lately when i shut the filter system down (de / 75 / inground pool) , the de is seeping in reverse back through the pump and filling the lines. when the filter is turned back on there is a huge discharge of air and earth into the pool through the jets. any hints of what is going wrong?

Is the check valve working. Sounds like you may have to service or replace the check valve.
