Hi,
I have a problem with my Haywood EC65 perflex DE filter. It's working fine but 2 days ago after shutting the filter off
I bumped it and I felt a snap and lost resistance. I took it apart and found that the E-ring had fallen off, looked like an easy fix so I bought a new e-ring put it on and put it back together, it worked fine yesterday and I bumped after use
and all was well. I ran the filter today and after shutting it down an hour ago I bumped it and the same thing happened again, no resistance and a snapping sound. I'm sure when I take it apart tomorrow the new e-ring will be missing. Does anyone know what problem can cause the e-ring to keep snapping off?
It's the e-ring on the top closest to the bump handle and yes It was put on correctly snapped in tight like it's always been.

Thank You
