I've got a Grundfos w/timer installed on my 75 gal. water heater. The pump is about six years old and the new heater was installed just a couple of months ago.
After having some additional outside plumbing work done one day last week , I discovered the pump had stopped functioning (same day) and, I suspect, burned up. I unplugged it immediately and one would have had 1st degree burns if the casing had been touched. I let it cool down for an hour+ and plugged it in and it rapidly heated, w/no pump movement, although the timer was functioning.
Can this failure be attributed to the plumber not deactivating the pump while the water was turned off during the time he was working outside? (about 3 1/2 hrs.) I'm not sure what the flow rate is on the pump but could this have caused the failure? I just cannot believe this is a coincidence.
Opinions appreciated...
