Dave In every instance we have to do a 3 head calc when there are at least 3 heads in the room where the steep pitched roof is (over 8:12). We've also had to use the UL listed flow required for the head up to 8:12 pitched ceilings which is 18gpm per head. These homes are also usually large homes on wells which means we have to put in 600+ gallon (10 minutes X 54gpm = 540 gallons) tank and a pump. The AHJ's want a cushion just in case the pump is pumping more than the required 54gpm and draining the tank too fast.

This leaves it up to the local AHJ which has resulted in a few different requirements. I would like to hear from anyone who may hold the solution to this on going dilemma. What does your AHJ required you to do in these situations?? Any help would be greatly appreciated. Thanks Dave Killey Fire Busters Inc No virus found in this outgoing message. Checked by AVG.
