How to Turn Water off to Water Heater


One of the most important things you can do to maintain your water heater is to know how to turn the water off to it. This may seem like a no-brainer, but if there is ever a problem with your water heater, being able to quickly and easily turn off the water will help prevent further damage.

  • Locate your water heater and find the shut-off valve
  • This is usually located on the incoming water line to the water heater
  • Turn the handle of the shut-off valve to the “off” position
  • You may need to use a wrench to turn it if it is stuck
  • Once the shut-off valve is in the off position, no more water will flow into your water heater tank

How To Shut Off Water Supply to Water Heater

Where is the Water Cut off Valve to the Water Heater?

If you need to turn off the water to your water heater, the shut-off valve is most likely located near the bottom of the unit. If your water heater is gas-powered, there may also be a shut-off valve on the gas line leading to the unit. In either case, turning off the valves will stop all water flow into and out of the unit, so be sure you know how to relight a pilot light or restart a gas water heater before proceeding.

Your home’s hot water heater is an essential part of your plumbing system, providing you with hot water for bathing, cooking, and cleaning. Like any other appliance in your home, your hot water heater requires regular maintenance to keep it running efficiently. Part of this maintenance includes knowing how to properly shut off the water supply to your hot water heater.

There are two main types of shut-off valves for a hot water heater: the cold water inlet valve and the hot water outlet valve. The cold water inlet valve is located at the top of the tank and controls the flow of cold water into the tank. The hot water outlet valve is located at the bottom of the tank and controls the flow of hot water out of the tank.

If you turn off the water to your home, you will also need to turn off the water heater. If you do not, the water inside the heater can become stagnant and start to grow bacteria. The water heater should have a switch or knob that allows you to shut it off completely; if it does not, then you will need to unplug it from the power source.

Is It Safe to Turn off Water to Water Heater

If you’re thinking about turning off the water to your water heater, you might be wondering if it’s safe to do so. The answer is that it depends on the type of water heater you have. If you have a traditional tank-style water heater, it’s generally not safe to turn off the water completely.

This can cause the tank to overheat and potentially rupture. However, if you have a tankless water heater, it’s usually safe to turn off the water. Just be sure to follow the manufacturer’s instructions carefully.


If your water heater is leaking or you need to perform maintenance on it, you’ll need to know how to turn the water off to it. Luckily, it’s a pretty straightforward process. First, locate the main water shut-off valve for your home and turn it clockwise to shut off the water.

Next, open a faucet in your home to release any pressure that may be in the lines. Finally, head back to your water heater and turn the knob on the cold water inlet pipe clockwise until it’s turned all the way off.
