About this file
This is a Fire Hydrant Inspection and Flow Test Record documenting the inspection and testing of Fire Hydrant #155 located in Area II near Building 10150 at Nellis Air Force Base (99th CES). The inspection was completed on November 6, 2019, by Inspector LOVE-G and is conducted on a five-year basis in accordance with Unified Facilities Criteria (UFC) 3-600-02 and National Fire Protection Association 25 standards.
The inspection encompasses multiple components including verification of the dry hydrant's accessibility, leaks, and worn threads; operational testing of yard monitor nozzles; examination of hose house conditions and valve functionality; and comprehensive flow testing. The Mueller brand hydrant (Model No. 531, manufactured in 1997) was tested and verified to be operational and in proper working condition. Key flow test results include a static pressure of 110 PSI, residual pressure primary of 20 PSI, residual pressure secondary of 0.9 PSI, pitot pressure of 10 PSI, and a total flow during test of 591 GPM at a 2.5-inch outlet size with 0.9 coefficient. All inspection checklist items were marked complete with "X" marks, including verification that the hydrant was left in service. The water pressure-flow curve graph plots the relationship between flow (in GPM) and pressure (in PSI), showing the hydrant's performance characteristics with measurements at 531 GPM and 591 GPM points.
