Pick a city and home age. Excess street PSI through an older PRV can push more gallons through drips and open fixtures.

Municipal supply vs the 40–60 PSI home band — then size waste when the valve ages.
A pressure-reducing valve sits near where the main enters the house. It lowers high street pressure to a gentler home range so pipes, fittings, and fixtures last longer.[1] Think of it as a speed limit for water inside your walls — not a water filter.
Where this comes from: Plumbing codes and manufacturer guidance commonly target roughly 40–60 PSI at fixtures; many utilities deliver higher at the curb. Educational — confirm with a gauge on a hose bib.
Why pressure fluctuatesPick your city (or override). Watch municipal vs recommended on the picture. Recommended midpoint is about 50–55 PSI inside the 40–60 band. Excess street pressure that never gets stepped down means fixtures flow harder and tiny drips waste more.[2]
Where this comes from: EPA WaterSense — Fix a Leak Week (small leaks add up); local utilities publish typical delivery pressure ranges.
How meter reads workPRVs wear, stick, or drift. Newer installs usually hold the band; decades-old valves can pass excess pressure. The Pressure Pulse toy scales an educational gallons/day estimate by excess PSI × home age — not a scare number, a planning hint.
Overnight meter testHigh pressure alone is not a leak. If the meter moves overnight with everything off, you have flow to find. If the meter is still but showers feel harsh and you hear hammering, focus on PRV adjustment/replacement with a licensed plumber.
Silent toilet leak costPressure waste and a bill spike can travel together (harder flow through open fixtures and weeps). Separate “too much PSI” from “too many gallons on the statement” with the bill tools.
