Following installation of the T&P Relief Valve, the valve lever MUST be operated AT LEAST ONCE
A YEAR by the water heater owner to ensure that waterways are clear. Certain naturally occurring
mineral deposits may adhere to the valve, blocking waterways and rendering the valve inoperative. When
the lever is operated, hot water will discharge if the waterways are clear. PRECAUTIONS MUST BE
TAKEN TO AVOID PERSONAL INJURY FROM CONTACT WITH HOT WATER AND TO AVOID
PROPERTY DAMAGE. BEFORE operating lever, check to see that a discharge line is connected to the
valve, directing the flow of hot water from the valve to a proper place of disposal. If no water flows when
the lever is operated, replacement of the valve is required. TURN THE WATER HEATER “OFF” AND
CALL A PLUMBER IMMEDIATELY.
This device is designed for emergency safety relief and shall not be used as an operating control. A relief
valve functions by discharging water in an emergency. Therefore, it is essential that a discharge line be
piped from the valve in order to carry the overflow to a safe place of disposal. The discharge line must be
the same size as the valve outlet, must pitch downward from the valve, and terminate at least 6” above a
drain where any discharge will be clearly visible.
