How often should the temperature pressure relief valve be tested in a hot water heating system?

The recommended practice for testing the temperature pressure relief valve in a hot water heating system is to do so every 30 days. This frequency ensures that the valve is functioning correctly and can effectively prevent excessive pressure and temperature from building up in the system, which is crucial for maintaining safety and preventing potential hazards, such as explosions or leaks.

Regular testing helps identify any issues early, allowing for timely maintenance or replacement of the valve if necessary. While other intervals may seem reasonable, testing every 30 days strikes a balance between safety and practicality. More frequent testing, like every week, could be excessive and impractical for most systems, while annual testing may not provide sufficient oversight to catch problems that can develop more rapidly.
