(A) No person shall install or maintain a
water service
cross connection
to any
premises
where a
booster pump has been installed, unless an
approved
method is in place and is operational to maintain a minimum suction pressure as
prescribed in the following:
(1) For booster
pumps not intended to be used for fire suppression, no person shall install or
maintain a
water service
cross connection to any
premises where a
booster
pump has been installed
on the service line to or
within such premises, unless such
booster pump is equipped with a low
pressure cut-off designed to shut-off the
booster pump when the pressure in the
service line on the suction side of the pump drops to ten pounds per square
inch gauge or less.
(2) For booster
pumps used for fire suppression, also referred to as fire pumps, no person
shall install or maintain a
water service
cross connection to any
premises where a fire
pump has been installed on the service line to or within such
premises, unless
the pump is equipped with one of the following:
(a) A low suction throttling valve which is a
pilot-operated valve installed in the discharge piping that maintains positive
pressure in the suction piping, while monitoring pressure in the suction piping
through a sensing line. The valve
must
shall throttle the discharge of the pump when
necessary so that suction pressure will not be reduced below ten pounds per
square inch gauge while the pump is operating.
(b) A variable speed suction limiting control
which is a speed control system used to maintain a minimum positive suction
pressure at the pump inlet by reducing the pump driver speed while monitoring
pressure in the suction piping through a sensing line. It will be set so that
the suction pressure will not be reduced below ten pounds per square inch gauge
while the pump is operating.
(3) Booster pumps used for fire suppression,
also referred to as fire pumps, installed prior to August 8, 2008, which are
equipped with a low pressure cut-off as defined in paragraph (A)(1) of this
rule, are not required to be modified solely for the purpose of meeting the new
methods accepted after this date, under paragraph (A)(2) of this
rule.
(B) The water
consumer shall maintain the low pressure cut-off device, the low suction
throttling valve, or the variable speed suction limiting control in proper
working order and certify to the supplier of water, at least once every twelve
months that the minimum suction pressure sustaining method is operable and
maintained in continuous operation.
(C) The supplier of water shall maintain
electronic or paper records of inventory of
booster pump installations.
Electronic or paper records certifying operation
must
shall be
retained for a period of five years.
(D) The provisions of this rule shall be
followed notwithstanding inconsistent provisions in the "Great Lakes-Upper
Mississippi River Board of State and Provincial Public Health and Environmental
Managers' Recommended Standards for Water Works."
(2012).
