Where shall combination temperature and pressure relief valves be installed?

Combination temperature and pressure relief valves must be installed in accordance with their listing requirements and the manufacturer's instructions to ensure safe and effective operation. These valves are critical safety devices designed to prevent excessive pressure and temperature buildup in water heaters or similar appliances.

The listing requirements ensure that the valve meets specific safety and performance standards. Meanwhile, the manufacturer's instructions provide essential guidance on where and how the valve should be installed for optimal functionality and safety. Proper installation is crucial; failing to follow these guidelines could result in improper operation, which may lead to hazardous situations such as leaks or dangerous pressure buildup.

Local codes can vary, but they typically align with national standards and regulations. Therefore, it is not sufficient to rely solely on local codes or the discretion of the manufacturer without referring to the specific listing requirements and installation instructions pertinent to the valve in question. Additionally, arbitrary installation anywhere in the system would compromise the valve's purpose and effectiveness.
