We were told to replace our pressure relief valve as our tank is leaking about 1 gal. per day, and the water gets cold quickly. My question is: To change the valve, do we need to turn off water, turn off gas, drain tank? The valve came with no instructions. Please advise.
Kind Sir, since you use the passive
voice in your inquiry, “you were told” might one inquire by whom? A
T&P relief valve on a gas water heater would in no way account for
a lack of hot water if the leak is
one gallon per day. The average recovery on a gas water heater is
40 gallons per hour. Something else is wrong. You do need a pro.
Please make sure that the leak is from the relief valve and not the
tank itself or you will need a pump
and wet-vac shortly.
