How do you size a water service line?

Three Steps to Sizing Plumbing Piping Systems

1. Add up the total number of water supply fixture units (wsfu) required in the facility.
2. Estimate demand using the table from the IPC that correlates wsfu to expected demand.
3. Size the pipe using demand vs. friction loss curves found in the IPC charts.
