Water drips from valve on water heater
Q. I have a gas water heater in my home that was installed six years ago. About four months ago it started dripping from the pressure relief valve. Thinking that the valve was faulty, I replaced it. However the new one is doing the same thing. Any idea what may be causing this?
A. You didn’t mention it, but are you also getting very hot, even steamy water at the faucets? If so, the thermostat on the heater may be set too high. Lower it and see if this solves the problem.
If the water temperature is not unusually high, the problem may be a change in the pressure of the water system. Assuming that you are on a city water system, something may have changed in the last few months; the city pressure may have been raised or a pressure reducer may have failed. You should have a licensed plumber check your water system out to determine what is causing the dripping at the p&t (pressure and temperature relief) valve. He or she may need to install a pressure reducer or a small expansion tank to take care of the problem.by
