Dirty Pool Water

Why is My Hayward EC40 DE Filter Not Working?

This is a common question. The scenario goes something like this: You turn on your filter, the water flow is great but shortly thereafter, anywhere from 2 minutes to 15 minutes or more, you notice the water flow slows down. If left alone the flow coming from your Hayward EC40 DE filter all but stops.
