What is the key benefit of using a pressure relief valve in a plumbing system?

The key benefit of using a pressure relief valve in a plumbing system is to prevent pipe bursts. Pressure relief valves are designed to automatically release excess pressure that builds up in a plumbing system. If the pressure exceeds a predetermined level, the valve opens, allowing some of the water to escape and thereby reducing the pressure within the pipes. This action protects the integrity of the plumbing system by preventing potential damage that could occur due to overly high pressure, such as ruptured pipes or fittings. Maintaining proper pressure not only ensures the longevity of the plumbing infrastructure but also minimizes the risk of leaks and water damage within walls and other structures.
