Watts 254702 Temperature Pressure Relief Valve 150 Psi

Product Description

The WATTS 254702 is a temperature and pressure relief valve rated to 150 PSI, designed to protect water heaters and hot water storage tanks from dangerous overpressure and overtemperature conditions. When system pressure or temperature exceeds safe limits, the valve opens automatically to discharge water and relieve stress on the tank and associated piping. This type of safety valve is a required component on nearly all residential and light commercial water heating systems and is installed by licensed plumbers during new installation or replacement service.

The 254702 is suited for residential and light commercial water heater applications where a T and P relief valve is required by code. It provides automatic protection against both excess pressure and excess temperature, making it appropriate for use on gas, electric, and indirect-fired water heaters in a range of system configurations.

Key Features

• 150 PSI pressure relief rating protects water heaters from overpressure events
• Combined temperature and pressure relief function in a single valve body
• Automatic discharge operation requires no manual activation during a relief event
• Compact form factor suitable for standard water heater T and P port connections

Compatibility

Designed as an OEM-style replacement T and P relief valve for residential and light commercial water heater installations requiring 150 PSI rated protection.

Installation Notes

Installation and replacement of temperature and pressure relief valves should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the cold water supply and disconnect power or gas to the water heater before beginning service. A discharge pipe must be run from the valve outlet to a safe drain location per code requirements. Never cap, plug, or restrict the discharge outlet of a T and P relief valve.
