Fixed suction for below ground water supply

The design of any fixed suction provided for a fire brigade pumping appliance to draught from a below ground water supply is to satisfy Clause 4.4 of Australian Standard AS 2419.1-2017. The maximum length of dry pipe between lowest section water level and large bore suction connection is not to exceed 2.8 m due to the limitations of the primer on the fire brigade pumping appliance.

Note: The primer is used during draughting operations to remove air from the fixed suction pipework and semi rigid suction hose that is connected to the large bore suction connection.
