Where should the TPR valve be located on a hot water tank?

The temperature and pressure relief (TPR) valve should be located in the upper part of a hot water tank, typically within the upper 6 inches, to effectively perform its safety function. The TPR valve is designed to open and release water when the temperature or pressure inside the tank exceeds safe levels, preventing potential hazards such as tank rupture or explosion.

Positioning the valve higher on the tank allows it to quickly respond to dangerous conditions by venting excess pressure or temperature safely. If the valve were placed lower, it might not react promptly enough to prevent a disaster, as rising steam and hot water would take longer to reach the valve. Additionally, the valve's installation at the top helps ensure that it can discharge water without obstruction, providing an effective safety mechanism for the entire system.
