I have a Pentair autofill. The float in the autofill keeps getting stuck and filling too much water. I have changed the float at least 10 times this summer, and each week I return and have the same issue. I have inserted a metal trap and a sediment trap into the line to try to stop the small carbon like particles from accumulating in the autofill. This seems to be the problem. I am at a loss though as to what else to do. I use well water and my pool was staining before the metal filter was inserted. The sediment trip may have helped some, but not enough.
