Stop the Pressure! Ultimate Guide to Relieving Water Heater Pressure Valves

Water heaters are essential appliances in our homes, providing us with hot water for showers, baths, and other household tasks. However, if the pressure inside the water heater becomes too high, it can lead to dangerous situations. That’s why it’s crucial to know how to release water heater pressure valve safely and effectively.

Step 1: Identify the Pressure Relief Valve

The pressure relief valve is typically located on the top or side of the water heater. It’s a brass or plastic valve with a small lever or handle.

Step 2: Gather Necessary Tools

You’ll need a bucket or hose to catch the water that will be released, as well as a wrench or pliers to turn the pressure relief valve.

Step 3: Turn Off the Water Supply

Locate the main water supply valve for the water heater and turn it off. This will prevent more water from entering the heater while you’re releasing the pressure.

Step 4: Open a Hot Water Faucet

Open a hot water faucet somewhere in your house to allow the hot water to escape. This will help reduce the pressure in the water heater.

Step 5: Turn the Pressure Relief Valve

Slowly turn the lever or handle of the pressure relief valve counterclockwise. You should hear a hissing sound as the water begins to release.

Step 6: Allow Water to Flow

Let the water flow until it slows to a trickle. This may take several minutes.

Step 7: Close the Pressure Relief Valve

Once the water has stopped flowing, slowly turn the pressure relief valve clockwise to close it.

Step 8: Turn On the Water Supply

Return to the main water supply valve and turn it back on.

Step 9: Check for Leaks

Inspect the pressure relief valve and surrounding area for any leaks. If you notice any leaks, tighten the valve further or contact a plumber.
