You may want to talk to you contractor about a single supply for all four units fire system, or one larger dom. Supply in one unit and 3 smaller supplies in the other units. That way only one larger backflow, and you can still zone by unit if the GC wants, or at least by floor.

We've got this subdivision where the previous FP contractor designed them to 13D's now our design is being questioned since we provided a four head calc resulting in larger BFP's, larger piping and a different style of sprinkler to be able to accomodate the low water pressure. The subdivision is wondering why our design is so different than the previous FP contractors.... gotta love it! The local AHJ is no help wither since they pretty much rubber stamp everything 'approved' anyway. A.P.Silva <[EMAIL PROTECTED]> wrote:> NO. The application of 13D/R does not depend on the water supply.
