● The end of the discharge line should not be threaded or concealed and should
be protected from freezing. No valve of any type, restriction or reducer coupling
should be installed in discharge line.
NOTICE:
The diagram below illustrates a pressure only relief valve. If local codes
require a combination temperature and pressure relief valve be installed, an
extension piece may be needed.
NOTICE:
Local codes govern the installation of relief valves. If local codes require
that a temperature and pressure relief valve should be installed the manufacturer
recommends a type 40XL Watts T&P relief valve or an equivalent model be used.
NOTICE:
Manual operation of relief valves should be performed at least once a
year. Turn off the electrical power and gas shutoff valve. Lift and release lever on
the relief valve and check the manual operation of the relief valve. You should
take precaution to avoid contact with the hot water coming out of the relief valve
and to prevent water damage.
NOTICE:
If the relief valve on the system discharges periodically, this may be due
to thermal expansion in a closed water supply system. Contact the water supplier
or local plumbing inspector on how to correct this situation. Do not plug the relief
valve.
