Kevin, That's the beauty of this forum. It is generally a group that can help but never (rarely) tries to stuff crow down our throats when we've missed something. That is unless it's Church or Leyton, those guys are ruthless!! :)

I guess my comment was slanted from the view that in the text for NFPA 24-1995. "The minimum rate of flow shall be not less than the water demand rate of the system, which is determined by the system design, or not less than that necessary to provide a velocity of 10 ft/s , whichever is greater." The standard changed on the next revision to it's present wording......... I find that crow is best eaten while it is still warm, it sticks in your throat less Kevin Law, PE Bechtel National, Inc.

I'm looking at the 2010 version, maybe older versions contain the word 'any'.
