A fire flow test provides pressure and flow data at specific fire hydrants within the District’s distribution system. The data can be used to assess the pressure and flow available for fire protection, sprinkler system design, mainline design, and proper sizing of domestic and/or fire service lines.
A fire flow test requires testing two fire hydrants: Flowing & Residual. The first hydrant is the flow hydrant, which is located closest to the property being tested. The second hydrant is the test (residual) hydrant and is located directly upstream or downstream from the flow hydrant.
