Recently we had an extended water outage. When water came back, pressure in the lines was much higher. The hot water heater started leaking from the pressure release valve and after flipping it a few times, it didn't stop, so I was prepared to go replace it, but then I accidentally pushed on the end of the pull bar that goes to the valve and the flow stopped.
Tried flipping it again, it leaked again, pushed the bar and it stopped.
Am I right in thinking the spring is shot, time to replace it?
