How do I test my PRV valve?

As a responsible homeowner or building owner, it's crucial to keep your piping systems safe. Your piping system's safety largely depends on the Pressure Release Valve (PRV). It's a critical component of any plumbing system and is responsible for releasing excess pressure, preventing water heater rupture, pipe damage, and other mishaps. However, a non-functional PRV can lead to serious consequences, compromising the safety of your piping system and putting you at risk of a water damage emergency.

To ensure your piping system's safety, it's important to periodically test your PRV to identify and fix any issues. In this extensive guide, we'll walk you through the entire process, teaching you how to test a PRV Valve and keep you and your system protected.

Understanding PRV Valve.

A PRV valve, also known as a Pressure Relief Valve, is a safety device that features a spring-loaded, spring-actuated mechanism that opens or closes depending on the pressure within the plumbing system. When the pressure exceeds a certain level, the valve automatically opens, releasing the excess pressure and protecting your system from potential damage. As a result, the valve helps to reduce the pressure when it reaches unsafe levels.

Types of PRV Valves.

The two main kinds of PRV Valves are single-stage and dual-stage. As the name suggests, single-stage valves have a single mechanism to release excess pressure. In contrast, dual-stage valves have two mechanisms that act in tandem to ensure piping system safety. Dual-stage valves are recommended for greater pressure reduction control.

Why Test Your PRV Valve?

Your PRV Valve plays a critical role in protecting your piping system from potential damage. If not appropriately maintained or tested, the valve can quickly fail, leading to a broad range of plumbing issues, including pipe leaks, water damage, and rupture. Testing your valve ensures that it's functioning correctly and will protect your plumbing system as designed.

How Often Should You Test Your PRV Valve?

Periodic testing of your PRV Valve is crucial to ensure that it's always functioning correctly. Experts recommend testing the valve at least once every 6 to 12 months for optimum safety.

Testing Your PRV Valve.

Step 1: Turn off the Water Supply.

Before you start testing the valve, it's important to turn off the water supply. Turn off the control valve upstream of the PRV to stop water from entering the system and onto the PRV Valve.

Step 2: Check Your Pressure Gauge.

Locate the pressure gauge at the outlet side of your PRV Valve. Record the PSI readings on the pressure gauge.

Step 3: Lift the PRV Valve's Test Lever.

PRV Valves come with a test lever that helps simulate excess pressure, which triggers the valve to open. Lift the test lever gently upwards, allowing it to move back before releasing it. Doing so should release water from the valve's discharge opening.

Step 4: Check Your Pressure Gauge Again.

After lifting the test lever, check the pressure gauge again to determine if the valve opens correctly. If the gauge reading decreases, your valve is releasing pressure correctly.

Step 5: Turn Your Water Supply Back On.

Finally, turn your water supply back on and monitor your plumbing system for proper functioning and leaks. If there are any visible leaks or issues, turn the water supply back off and contact a professional plumber for assistance.

Conclusion.

Testing your PRV Valve is an essential part of maintaining your piping system's safety. By following the steps above, you can keep your valve functioning correctly and prevent potential plumbing disasters. If you notice any issues with your valve or plumbing system during the test, it's critical to contact a professional plumber immediately to assess the situation and make any necessary repairs to avoid serious issues. Regular testing and maintenance can keep you and your property safe from plumbing issues, saving you time, repair costs, and frustration in the long run.
