These probably are questions everyone knows the answers to but I can't find the answers:
1. If you have a mixed occupancy (residential & Business) and your design is a 13R does your riser need to be at least a certain size or just large enough to serve the hydraulic area? 2. Because there is something other than residential in the building would I not need a backflow on the riser?
