What should be considered when setting the relief valve for a water system?

When setting the relief valve for a water system, it is essential that the pressure does not exceed the nominal working pressure. The nominal working pressure represents the maximum pressure the system is designed to handle safely without risk of damage or failure. By ensuring that the relief valve is set to this level, you can maintain the system's integrity and avoid potential hazards such as leaks, ruptures, or catastrophic failures that can arise from excessive pressure. This practice upholds safety standards and prolongs the life of the system components.

While other factors such as how easily the valve can be reset or its position in relation to the highest pressure point are important considerations, they do not take precedence over ensuring the valve is set within the safe operational limits of the system. Additionally, while a relief valve is a critical safety feature, it is not the only one required in a water system, which may call for other safety devices depending on the specifics of the setup.
