Safety relief valves should be
, by a
licensed plumbing contractor or
authorized inspection agency, to
ensure that the product has not
been affected by corrosive water
conditions and to ensure that the
valve and discharge line have not
been altered or tampered with
curring conditions may corrode
the valve or its components over
time, rendering the valve inop-
erative. Such conditions are not
detectable unless the valve and
its components are physically
removed and inspected. This in-
spection must only be conducted
by a plumbing contractor or au-
thorized inspection agency — not
by the owner. Failure to reinspect
the boiler relief valve as directed
could result in unsafe pressure
buildup, which can result in
severe personal injury, death or
substantial property damage.

naturally occurring mineral de-
posits may adhere to the valve,
rendering it inoperative. When

weeping is the valve and not over-pressurization of
the system due to expansion tank waterlogging or
undersizing.
