De filter Grid

I replaced my de filter grids, the DE does not adhere to the grids, no matter small amount of DE I put in I can see it being pumped into the pool?

Hi Den727,

The first thing I would check is that the valve is not plumbed backwards, the pipe from the pump should go to the port labeled pump and the pipe from the valve back to the pool should be plumbed to the port labeled return. If the valve is plumbed properly, then I would check out all of the items we have listed in this Article on Troubleshooting DE Back in Pool.

Thank You

Patrick
