      I had a leak at the pressure/temperature relief valve on my 5 year old water heater. It would not shut off, continually draining. I had a plumber replace the valve but recently noticed that it is still leaking, but not continually.

      What can be setting off the relief valve? If I check my incoming water pressure (from the street) what should it be? Anything else I should be checking?

      Temperature and pressure valves use temperature and/or pressure to open. On a water system that has backflow preventers, no thermal expansion tank, and a line pressure close to the T&P pressure, as the water heats it expands and increases the pressure enough to open the valve. Also opening a faucet or other fixture in the house brings the increased pressure back to line pressure. You need to install a thermal expansion tank for the system. Good luck
