(a) Booster pumps that are not intended to be used for fire suppression shall be equipped with a low-suction 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.
(b) Booster pumps or fire pumps that are used for fire suppression and installed after August 8, 2008 shall be equipped with a minimum pressure sustaining valve on the pump discharge, which throttles the discharge of the pump when necessary to keep the suction pressure from dropping below ten pounds per square inch gauge.
(c) It shall be the duty of the water consumer to maintain the low pressure cut-off device and/or minimum pressure sustaining valve, in proper working order, and to certify to the Water Services Superintendent, at least once every twelve months that the minimum pressure sustaining method in place is operating properly.
