Hayward DE Filter Blew top of Air Release valve off??????

[bell7272]

Hello All,

This morning my pool was running and pressure was fine. Everything sounded normal in it's running.

Went out a few minutes later and the top of the Air release valve had ripped / blew off. This looked like is was a solid piece and the top just blew off.

Have you ever seen this???

What would have caused this??

History: DE filter (7 yrs old) was completely cleaned in April 2013.

Is this merely fatigue or could it be other issue I need to check. No issues.

I did call Hayward tech support, but the person I got was nothing more than an order taker and was no help.


Thanks to all who respond.
