DIY Water Heater Line Repair

If your hot water heater is leaking, it's typically an issue with the supply line that carries water from the heater through your home. Calling a plumber can remedy the problem, but it can be costly and it may take some time before you can get someone to come out and remedy the issue. Replacing the supply line is fairly simple and something you can tackle yourself with the right tools. Read on to learn how you can replace the line connected to your water heater.

Preparation

Before you begin to make repairs, be sure to turn off the gas line if your water heater is gas, and turn off the breakers if your water heater is electric. Measure the length of the pipe you will need to replace so you can ensure you purchase the correct size. It's recommended you buy a piece of pipe a bit longer in order to allow for any errors. Turn off the cold water supply that goes to your water heater and allow the pressure to drain, then lift the pressure relief valve. Using a wrench, loosen the nuts that connect the current line to the water heater and the ones connecting it to the wall. Remove the old pipe and wipe the connecting bolts with a dry towel.

Repair

Once you've made sure the new pipe is the correct length, it's time to reconnect the new line. Using the wrench, re-tighten the nuts and bolts on the side connecting it to the wall. Then, do the same thing with the side connected to the water heater. You should use several layers of plumbing thread tape to help create a tight seal. Make sure all nuts and bolts are as tight as possible to prevent future leaking. 

Getting Hot Water

Once you've reconnected your new line, it's time to turn the water heater back on to ensure everything is working properly. Turn on the closest supply faucet first, and then turn back on the cold water supply line. Let the tank refill completely, and then check the supply faucet to ensure water is coming out. Once you see a steady stream, you may turn the supply faucet back off. Turn the breaker back on if you have an electric water heater, but make sure the supply faucet is producing water so the tank is full. If not, it can damage the heating element. If you have gas, turn the gas valve back on and then run your hot water until it's coming out at an acceptable temperature.
