A Watts Water Technologies Company
REINSPECTION OF T&P RELIEF VALVE: Temperature and
Pressure Relief Valves should be reinspected AT LEAST
ONCE EVERY THREE YEARS by a licensed plumbing contrac-
tor or authorized inspection agency, to insure that the product
has not been affected by corrosive water conditions and to
insure that the valve and discharge line have not been altered
or tampered with illegally. Certain naturally occurring conditions
may corrode the valve or its components over time, rendering
the valve inoperative. Such conditions are not detectable unless
the valve and its components are physically removed and in-
spected. Do not attempt to conduct this inspection on your own.
Contact your plumbing contractor for a reinspection to assure
continuing safety.
FAILURE TO REINSPECT THIS VALVE AS
DIRECTED COULD RESULT IN UNSAFE TEMPERATURE
OR PRESSURE BUILD-UP WHICH CAN RESULT IN SERI-
OUS INJURY OR DEATH AND/OR SEVERE PROPERTY
DAMAGE.
IMPORTANT: 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"(152mm) above the floor drain where any
discharge will be clearly visible. For 100DT discharge line consult
your Watts agent.
