How to Open a Water Heater Pressure Relief Valve

As a homeowner, it is important to know how to open the T&P valve for safety reasons. There are situations where the valve can malfunction or become stuck, thereby preventing the release of excess pressure. In such cases, you may need to manually release pressure from your water heater.

The Sunshine Plumbers are the experts you can count on when you need professional water heater repair. Today, we’ll explain how a water heater pressure relief valve works and how to open it.

How Does a Water Heater Pressure Relief Valve Work?

This valve automatically opens when the pressure inside the water heater tank exceeds the preset limit (150 PSI or 210 degrees Fahrenheit). The valve opens to release excess heated water until the pressure and temperature drop back to safe levels. Once the temperature and pressure return to a safe and stable level, the T&P valve will close automatically.

The water heater pressure relief valve can malfunction as a result of mineral buildup, corrosion, sediment buildup, or mechanical failure. It's recommended to test your T&P valve at least once a year. This will help ensure that it's functioning properly and can protect your water heater in case of an emergency.

To test the valve, simply lift the lever on the valve. If the valve is functioning properly, water should flow out. If the valve doesn't open or if there's a leak, call a skilled plumber in Fish Hawk to replace it before you have a disaster on your hands. Here at The Sunshine Plumbers, we are here to help you keep your water heater in good order.

Steps to Open a Water Heater Pressure Relief Valve

• Locate the valve—the valve is typically located near the top of the water heater. It's usually a lever or a small red pull tab.
• Carefully lift the lever or pull the tab on the valve. The valve should open, allowing water to escape.
• Allow the water to flow until the pressure is relieved. This may take a few minutes.
• Once the pressure is relieved, carefully close the valve by pushing it down or turning it clockwise.

If the valve is stuck or does not open easily, do not force it because you could cause more damage to your water heater. Contact a professional plumber in Tampa for assistance.
