Water Service & Meter Sizing Calculator
Convert fixture units to demand by IPC Appendix E (E103), lay out the pressure budget from the main to the highest fixture, and size the service pipe and meter that satisfy it.
The pressure budget is where these calculations are usually won or lost. Static lift, meter loss, backflow preventer and pipe friction all come out of the same starting pressure, and the meter is often the largest single deduction.
