What is a routine maintenance procedure for a pressure-reducing valve?

Exercising the valve is a critical routine maintenance procedure for a pressure-reducing valve. This process involves opening and closing the valve periodically to ensure it operates smoothly and to help prevent it from becoming stuck. Regularly exercising the valve helps identify any potential issues, such as wear or obstruction, and ensures that the valve can function effectively under pressure changes in the system. By maintaining the ability to smoothly manipulate the valve, operators can ensure more reliable performance and longevity of the valve in managing water pressure.

While replacing the valve, testing the pressure settings, and cleaning the valve can be important in their own contexts, these actions do not encompass the routine maintenance aspect as effectively as exercising the valve does. Replacing the valve is more significant and not regularly needed unless there’s a failure. Testing pressure settings checks if the valve is functioning properly but doesn’t necessarily involve the physical function of the valve itself. Cleaning the valve can be beneficial but isn't always a routine requirement. Exercising the valve encompasses a hands-on approach that aids in ongoing maintenance and functionality, making it the best choice for a routine practice.
