Fire Hydrant Management Goals The inspection, testing and maintenance of Tammany Utilities'' (TU) fire hydrants is critical to determining the readiness of the hydrants to provide water at fire emergencies. The inspections shall verify the location, accessibility, proper mechanical operation, and water flow from the hydrant. Annual Inspection
A flow test is a procedure to test the water flow and pressure achieved at a set point in time. This is done from the most hydraulically disadvantaged hydrant/s located on a fire system. The minimum requirements for servicing of fire hydrants is specified in AS 1851 section 4, and this requires: Annual inspection consisting of a water flow test.
Hydrant Flow Testing is an routine requirement of Australian Standards and ensure your fire protection system performs when you need it to..

1- Decide which hydrant will be the Test hydrant and which will be your Flow hydrant. The Test hydrant will be used to measure both Static and Residual pressures. It should be closer to a feed main than the Flow hydrant. 2- Decide how many Flow hydrants to use. As a general rule of thumb, you should flow enough hydrants at the same time so that the
