⚖️ ASPE / UPC (Limiting Fixture Static Pressure <80 PSI, Direct-Acting PRV Stations)

High-Rise Plumbing Pressure Zone Calculator

Divide tall multi-story building plumbing systems into vertical static pressure zones under ASPE guidelines & UPC: calculate floor pressure zoning (preventing static water pressure exceeding 80 PSI [550 kPa] at fixtures to eliminate pipe blowouts and valve noise), size redundant high/low flow Pressure Reducing Valve (PRV) stations (Cla-Val / Watts), and plumbing margins.

1. Project & Operating Inputs

PRV Valve Stations Installed (Station Count e.g. 8 Dual-Stage PRV Stations)
