Question about Hayward 48 Sq Ft Pro Grid Vertical Grid De Pool Filter
I had the same problem, and they suggested I had a tear or whole in one of the grids. After close inspection, I found no hole or tear, and the maniford was fine. I opened the multi-port valve and found the problem. It has a gasket inside and it had badly deteriorated. I replaced the gasket and no more problems with DE coming back into the pool.
