How to Turn Off a Water Heater in 7 Easy Steps
Even the most handy homeowners can sometimes find themselves baffled by the intricacies of a home’s plumbing system. One of the most common questions we get is: "How do I turn off my water heater?" Whether you’re planning a vacation, dealing with a leak, or simply want to save energy, knowing how to shut off your water heater is an essential skill. In this comprehensive guide, we’ll walk you through the process step-by-step, ensuring that you can turn off your water heater with confidence and ease.
Before You Start: Safety First
Before you begin, a few safety precautions are in order:
- Turn off the gas or electricity: For gas water heaters, locate the gas valve and turn it to the "off" position. For electric water heaters, turn off the circuit breaker or fuse that supplies power to the unit.
- Allow the water heater to cool: Water heaters can retain heat for a long time, so give it at least 30 minutes to cool down before attempting to turn it off.
- Wear gloves: To protect your hands from hot surfaces or water.
Step 1: Locate the Shut-Off Valve
The first step is to locate the shut-off valve. This valve is usually located near the bottom of the water heater, where the cold water pipe enters the unit. It will typically have a handle or knob that you can turn.
Step 2: Turn Off the Cold Water Supply
Once you’ve located the shut-off valve, turn it clockwise to close it. This will stop the flow of cold water into the water heater.
Step 3: Open a Hot Water Faucet
Now, open a hot water faucet somewhere in your house. This will allow the remaining hot water to drain out of the tank and prevent it from building up pressure.
Step 4: Turn Off the Gas or Electricity Again
Once the water has stopped flowing from the faucet, turn off the gas or electricity to the water heater again.
Step 5: Open the Pressure Relief Valve
Most water heaters have a pressure relief valve located near the top of the tank. Open this valve by lifting up on the lever or handle. This will allow any remaining pressure in the tank to escape.
Step 6: Drain the Water Heater
If you need to drain the water heater completely, connect a garden hose to the drain valve located at the bottom of the tank. Open the valve and allow the water to drain into a bucket or drain.
Step 7: Turn the Shut-Off Valve Back On
Once the water heater is empty, turn the shut-off valve back on by turning it counterclockwise. This will allow cold water to flow into the tank again.
