Added to my watched topics.
My diaphragm 120 pump is about 7 months old running 8 hrs a day.
I have a rebuild kit on hand.

I am an absentee pond owner and my pump is on a timer. If the diaphragm fails and it continues to run, will the pump be damaged? Heat build up or some other issue?
Trying to gauge if I should rebuild as a proactive measure.

Half acre 30 year old farm pond, Mebane NC. Aeration & feeder.
