Quick question for everyone here. When the situation prevents one from being able to provide a calculation back to the U.G. connection at the street when can you calculate the system back to the gauge on the riser ?
For example, if you have, say, 50 psi city pressure (worst case) on a system at the riser gauge couldn't one calc it to the base of the riser, add in your hose allowance and call it a day as long as your system demand is less than the lowest "day pressure" in the system ? In addition, if there any mention on this in NFPA 13 ?
