Greg, I think that option two would be ok. It seems that it's ok to have an auxiliary dry system off the end of a wet system, so an auxiliary wet system should work as well.

If we tried to tie on to the end of one system to feed the larger addition, that system would be approximately 56,000 sqft. Th other two options (I guess) would be to run 250' of 3" back to the main riser and create a new system for this addition, or use it for both additions with another 300' or so of main, or maybe to put in a new control valve and flow switch at each addition to supply them. I am not sure if the second option would meet the intent of the code and I am too confused to figure this out this early in the year. The other addition appears to be on a system that is already about 53,000 sqft and adding the addition would also put it around the 56,000 mark. Has anybody ever asked for a variance on something like this? It honestly doesn't make any sense to put it in a separate system (other than to meet code) because the operation of the system will not actually be effected. Especially in the way these systems are shaped, there are several different fire rated zones of much smaller area.
