Knowing where your water heater shut off valve is located is important for everyone. If there is ever an issue with your water heater, this will need to be turned off before any repair can be made. Since all models are slightly different, there are a few things you should look for to find it.
Find the Red Knob
Most water heaters have 2 valves at the top of the unit. You will see tubes leading in to each one. The red knob is always the shut off valve. The black knob is a release valve. If you have an electric water heater, you will also need to find the circuit it runs on and turn the power off before you service the water heater.
Let it Cool Off
If you need to work on the water heater, you will likely need to drain it. After you cut the water off, and turn off the power, you will want to allow it to cool off for a while before you do anything. Not doing this, and draining the tank before it cools can result in serious burns from scalding water.
Mark the Valve
If the valves are difficult for you to identify, go ahead and mark them in case you need to work on it again. This will save you a lot of time, and a potential headache later down the road.
