Do you understand standpipe flow tests? Standpipe flow tests are critical for ensuring that the fire department can get the proper pressure and flow from the hose connections at the most remote connection. Sometimes these flow tests fail **hint hint - watch the video** and you must take action to correct them.
NFPA 25 (2011) 6.3.1 requires standpipe flow tests at the most remote connection every 5-years. The flow is based on how many "risers" (standpipes) you have at the most remote level. It is also critical to understand that systems that were installed after 1993 must meet 100 psi residual pressure at the most remote outlet. If your system was installed before 1993 you only have to meet 65 psi at the most remote outlet.
Check out the video below to learn more about pitot tubes and how to check pressures.

3 年Hello, If you have 28 psi on the pitot with 1.75'' playpipe, the flow is about 460 usgpm. To reach 500 uspgm you can use a biger nozzle or a different combinaison with 2 outlets and different nozzle. The residual pressure to my understanding has not taken, maybe a gauge at the top of the riser is available for the residual pressure. This wasn't mention. Did the test really failed ?
Awesome! Great video. Thanks for sharing.

3 年Love this video Joshua, cool to see you taking advantage of these inspections to teach people and provide perspective for some of these less frequent, thus more obscure, parts of system maintenance!
