What's your expected flow rate? You could always tell the GC that they need to
rent you an empty pool truck to discharge into if they don't want the driveway
to get water on it. 1500' of hose should be a non-starter for you.

may pick a 120psi outlet pressure while flowing 750gpm, the extra play in the

Also definitely add a gauge on the inlet side of your backflow to make sure

In NFPA 13-2016 your best reference is going to be 22.8 which is an excerpt
from NFPA 45. You will be either Ord 1 or 2. This may or may not conflict with
any IBC requirements though if that is the regional governing code.

If the zone control has a control valve, check valve, drain, flow, and gauge
then yep. In this case though you generally wouldn’t have that single “system
riser” before those 4 assemblies though. You’d either just have your backflow

Looking on NFPALink for NFPA 13-2019 20.4.5.4 (5) says expanded plastics. Are
