Hayward D.E. Collector Bag Assembly for D.E. Separation Tank, CX900DBA

Hayward CX900DBA is the D.E. collector bag assembly for the Hayward D.E. separation tank. It is the genuine Hayward part.

What the separation tank is for

When a D.E. filter is backwashed, the spent powder has to go somewhere. A separation tank sits on the waste line and catches it, so the D.E. can be disposed of properly instead of being flushed into a drain or a yard. The collector bag inside is the piece that actually does the catching.

When to replace it

The bag takes the full force of every backwash. Over time it tears, splits at a seam or loads up past the point where rinsing helps. If the tank discharge turns cloudy with visible powder, the bag is passing D.E. rather than holding it, and the tank is no longer doing anything for you.
