For safety, how often should temperature and pressure relief valves on water heaters be tested?

Testing temperature and pressure relief valves on water heaters annually is important for maintaining safety and functionality. These valves are critical components that prevent the buildup of excessive pressure and temperature within the water heater, which could lead to potentially dangerous situations, such as explosions.

By conducting a yearly test, you can ensure that the valve is functioning properly and can release pressure as needed. This practice helps in identifying any signs of wear or malfunction before they lead to more serious issues. Regular maintenance, including this annual testing, is essential in prolonging the life of the water heater and ensuring safe operation for users.

While more frequent testing might seem beneficial, it is generally not necessary and may lead to unnecessary wear on the valve itself. Conversely, testing less frequently could risk the valve not operating correctly in an emergency situation, which underscores the importance of adhering to the annual schedule.
