How To Repair A Leaking Water Heater


An important component of a hot water heater is the pressure relief valve. When the internal temperature or psi gets too high, this valve will open and exert excess steam and water. On the occasion that this piece starts to leak, it is best to fix it as soon as possible.

Before attempting to fix this issue, try opening and closing the valve multiple times. Doing this will sometimes stop the leak, but if not then continue with the step-by-step guide.

Step 1: Before starting any maintenance, be sure to turn off the gas or electric depending on which type of water heater you have.

Step 2: Going into the water heater there is a cold water cut-off valve; close this.

Step 3: Grab a bucket and place it underneath the pressure relief valve. Proceed to open the valve underneath the water heater and the pressure relief valve to release excess water and pressure.

Step 4: Next, remove the overflow pipe from the pressure relief valve so you can unscrew the valve itself.

Step 5: Take the new pressure relief valve, wrap Teflon around its threads, and screw it into the water heater.

Step 6: Just as you did with the pressure relief valve, wrap Teflon around the threads of the pipe you previously removed. Then reattach the pipe to the valve.

Step 7: Re-open the cold water cut-off valve and check to see if the leak continues. If not, turn on the gas or electric so you can start using your water heater again!
