What is the maximum temperature setting for the temperature relief valve on a water heater?

The maximum temperature setting for the temperature relief valve on a water heater is 210 degrees Fahrenheit. This setting is critical because it ensures that the water heater operates safely and prevents the water from reaching excessive temperatures, which could lead to an increased risk of scalding or pressure buildup that could result in a rupture.

Temperature relief valves are designed to release water when the pressure or temperature exceeds safe limits. By setting the temperature limit at 210 degrees Fahrenheit, manufacturers provide a safeguard that accounts for potential temperature variations and ensures user safety when accessing hot water.

While lower temperature settings are also valid, they may not provide the necessary safety margins required in certain water heating applications. It's essential for plumbing inspectors and technicians to understand these standards to ensure compliance and safety in residential systems.
