Where should a pressure relief valve be installed in a hydronic piping system that has been reduced in pressure?

The installation of a pressure relief valve on the low-pressure side of a hydronic piping system is crucial for ensuring the safety and functionality of the system. A pressure relief valve serves the purpose of releasing excess pressure to prevent potential damage due to over-pressurization. In systems where pressure has been reduced, it's essential that the relief valve is positioned where it can effectively monitor and react to pressure levels.

By installing the valve on the low-pressure side, it ensures that any build-up of pressure that exceeds safe operating limits can be released promptly, protecting equipment and preventing failures. This positioning helps maintain the integrity of the hydronic system while keeping the pressure within safe operational boundaries. Thus, this strategic location enhances the overall safety and reliability of the system during operation.
