Most Hydraulically Disadvantaged Hydrant

Most Hydraulically Disadvantaged Hydrant

The most hydraulically disadvantaged hydrant is a hydrant landing valve or attack hydrant within the property that forms part of the fire hydrant system or combined system within a property. The most most hydraulically disadvantaged hydrant is typically installed at a location within the property that contributes to reduced water flow rate and pressure due to its location. Distance from the water supply feed and height above ground level are the two primary factors that adversely affect water flow and pressure.

The water supply flow and pressure of the most hydraulically disadvantaged hydrant must be tested yearly in accordance with Australian Standard AS1851.
