Safety relief valves should be
reinspected AT
LEAST ONCE EVERY THREE YEARS
, by a
licensed plumbing contractor or authorized
inspection agency, to ensure that the product
has not been affected by corrosive water condi-
tions and to ensure that the valve and discharge
line have not been altered or tampered with il-
legally. 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
inspected. This inspection must only be con-
ducted by a plumbing contractor or authorized
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.
Following installation, the
valve
lever must
be operated AT LEAST ONCE A YEAR
to
ensure that waterways are clear. Certain natu-
rally occurring mineral deposits may adhere
to the valve, rendering it inoperative. When
manually operating the lever, water will dis-
charge and precautions must be taken to avoid
contact with hot water and to avoid water
damage. Before operating lever, check to see
that a discharge line is connected to this valve
directing the flow of hot water from the valve
to a proper place of disposal otherwise severe
personal injury may result.
If no water flows,
valve is inoperative.
Shut down boiler until
a new relief valve has been installed.
