What maintenance task can help prolong the life of a hot water system?

Annual testing of pressure relief valves is crucial for maintaining a hot water system and significantly prolongs its lifespan. Pressure relief valves are safety devices that prevent excessive pressure buildup within the tank, which can lead to leaks or catastrophic failures. By testing these valves annually, you ensure that they are functioning correctly and can release pressure as needed. This preventive measure helps to avoid potential damage to the hot water system and ensures safe operation.

Regular maintenance like this not only enhances the longevity of the system but also minimizes the risk of emergency repairs, thereby providing peace of mind for the user. In contrast, tasks such as merely checking for leaks, changing filters, or cleaning the exterior may not address the internal pressures and safety mechanisms critical to the overall health of the hot water system.
