What is the purpose of checking pressure valves during maintenance?

The purpose of checking pressure valves during maintenance is fundamentally to ensure the safe operation of the hot water system. Pressure valves play a critical role in regulating and maintaining the pressure within the system. If the pressure within a hot water system is not properly managed, it can lead to dangerous situations, such as the risk of leaks, bursts, or even explosions. Regular maintenance checks allow technicians to identify any malfunctions or wear in the pressure valves, ensuring that they function correctly and that the system operates within safe pressure limits. This attention to safety helps protect both the infrastructure of the plumbing system and the users, making it a crucial part of ongoing maintenance practices.
