How often should the pressure relief valve be tested for proper function?

The pressure relief valve is a crucial safety device in hot water systems, as it ensures that pressure does not build up to dangerous levels within a water heater. Testing this valve annually is important to ensure its reliability and functionality. Over time, sediment and mineral build-up can affect the performance of the valve, compromising its ability to release excess pressure.

Annual testing allows for regular maintenance and ensures that any potential faults can be identified and addressed before they lead to more serious problems or pose a safety risk. This routine check is part of good plumbing practices and helps in prolonging the life of the hot water system by ensuring that all components are operating effectively. Regular testing at this interval aligns with recommendations from various plumbing codes and manufacturers, emphasizing both safety and operational efficiency.
