About two weeks ago I replaced a damaged H2O heater drain plug.
After replacement it was leak free until this afternoon. I removed the leaking drain plug and found a hairline crack in the plug.
I have had issues with the H2O heater tripping the fault indicator on the control panel as well as heavy shooting at the exhaust.
My question is, what caused the new drain plug to crack? Over temp? Over pressure?
It's plastic, thus I installed it about a 1/4 turn past finger tight, and it was leak free for the past two weeks, so I'm 100% sure I did not over torque the drain plug.
The pressure relief valve seems to operate OK when I manually operate it so I doubt that is the problem.
I'll need to check H2O temp at the sink Facuet to verify an over temp issue.
Anything I may be overlooking?
Thank you in advance.😁
