To update everyone that helped. We had a meeting with the AHJ and after talking he understood I was below the curve and he accepted the 31 GPM. He originally misunderstood and thought I was above my curve. Had to do some tweaking of the system to bring my safety factor up but it was approved. Thanks to all of you that helped, it is much appreciated. I'll buy you all a frosty mug of glycerine. Hey I have to get rid of the stuff somehow. Lol

I personally say you don't need to open 6 hydrants to get a 25% drop provided you meet or exceed the system demand. A 31 gpm difference is insignificant but unless you hit the magical 25%, you have to go with the demands of the AHJ. Suggesting an outside source for education is warranted. Any bets that such a suggestion would be well received? Roland On Jul 31, 2008, at 12:38 PM, John Drucker wrote: > Eric, > > Good point.
