AWWA-64344 2010 Field Guide: Hydrant Flow Tests DVD
The information in this video is based on AWWA Manual of Water
Supply Practices,Installation, Field Testing and Maintenance of Fire Hydrants (M17). It is
one of the AWWA Field Guide Series of instructional videos for water
distribution operators. Hydrant flow tests are used to determine pressure and flow-producing
capabilities at any location within a water distribution system. In
addition to providing a measurement of available water pressure at various
locations in the system, flow tests can reveal pipeline problems, such as
flow-reducing tuberculation, water-wasting leaks, and closed valves.
Hydrant flow tests are also called fire-flow tests, because they
provide information on the amount of water pressure available for fire
fighting. Hydrant flow tests also provide the added benefit of making sure fire
hydrants are in good operating condition in case of fire.
