Back from the old days of a playpipe and tip and 250 being about max average per stream, but still Code. It's funny, now with 1.75" and 2" nozzles, we use about half to 2/3 of the outlets. I did a 2000 gpm pump with 3 lines this morning. Talk about easy...
TD GRS Thats where I was going to send him - the question was for test header, I didn't see where the backflow testing came in... if its for number of hose valves on a test header, then what Duane said. Bobby Gillett See NFPA 20:Table 4.26 for test header requirements. Duane Johnson, PE I am use to providing one 2 ½" connection for every 250 gpm of system demand. I do not know where this requirement came from nor do I know of any requirement. Does anyone know of such a requirement?
