4.4.6. To Test Standpipe with Water Pressure
NFPA 14
– 2016,
Standard for the Installation of Standpipe and Hose Systems
addresses hydrostatic testing in
Section 11.4. Paragraph 11.4.5 states that an air test can be done if cold weather prevents testing with water.
Paragraph 11.4.7.2 states that if modifications to a standpipe (such as ‘jumping’ to higher floors) cannot be
isolated, then a pressure test is not required. Paragraph 11.4.8 further states that care shall be taken to ensure
that no portion of the piping is subject to freezing during cold weather. Based on these paragraphs, UNITED Fire
Systems
strongly recommends
:
If the monthly test can be avoided, do so.
If the monthly test cannot be avoided, perform testing during cold weather with air only’
If testing with water is deemed to be necessary, regardless of the weather, the Site Safety Manager should
ensure that the Method of Procedure (MOP) for such testing include, as its very first step, that the
STANDPIPE-
PAC™
outlet valve be CLOSED and locked in this position for the duration of the test.
The MOP should include using all drainage measures after testing, and making sure the standpipe is
completely drained, before the
STANDPIPE-
PAC™
outlet valve is re-opened.
Ensure there are no low points or traps without drains.
CLOSE Lockable Shutoff Valve BEFORE testing standpipe with water pressure.
Perform pressure test.
Use main drain, and all drainage valves at low points, to drain all water from standpipe.
CAUTION
After standpipe-has been filled with water for any reason, ensure that standpipe is completely empty of water
before refilling standpipe with air pressure. Use all available drain points to remove all water from the
standpipe. If, at any time, it is suspected that water has entered the
STANDPIPE-
PAC™
unit, contact UNITED
Fire Systems or your trained distributor before refilling standpipe with air pressure.
IMPORTANT
Although the
STANDPIPE-
PAC™
is equipped with an inlet check valve, it is important to take precautions to
prevent inadvertent water entry into the
STANDPIPE-
PAC™
piping and components. To prevent such water
entry,
always remember
to do the following:
ALWAYS unlock and close
STANDPIPE-
PAC™
outlet valve BEFORE testing standpipe by flooding
with water.
ALWAYS completely drain standpipe at main drain after testing standpipe by flooding with water, and
operate Auxiliary Condensate Drain Device until no water drains from device.
ALWAYS open and re-lock
STANDPIPE-PA
C™
outlet valve after completely draining water.
NEVER flood standpipe with water when
STANDPIPE-
PAC™
outlet valve is closed UNLESS
standpipe is being used by fire department.
NEVER expose
STANDPIPE-
PAC™
or Auxiliary Condensate Drain Device to freezing temperatures.
Ice can block
STANDPIPE-
PAC™
outlet and / or standpipe, possibly inhibiting standpipe use by Fire
Department in case of emergency.
