Descriptions
Temperature and Pressure
Relief Valve
In most cases, you are not required
to install a temperature and pressure
relief valve (T&P valve). However,
some local codes do require the
installation of a T&P Valve. If a T&P
valve must be installed, install it on
the hot outlet pipe according to the
valve manufacturer’s instructions and
local code.
If you install a T&P valve, turn on the
water supply to ensure that no water
drips from it. Next, operate the valve
manually two or three times to purge
the trapped air from the top of the
heater’s chamber, then close the
valve. Verify that water has stopped
flowing completely before connecting
the discharge pipe to the valve.
NOTICE: If a temperature and
pressure relief valve is installed, it
must be piped by minimum 1 inch
pipe to a suitable drain capable of
discharging 10 GPM. A splash cover
must be included to protect the
area of attachment to the wall. The
manufacturer will not be responsible
for any water damage that may occur.
WARNING! Do not cap or plug the
T&P relief valve or discharge pipe.
