WARNING
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,
rendering it 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, in an emergency, by discharging water. 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 and
must pitch downward from the valve and terminate at least 6" above a drain where any
discharge will be clearly visible.
