TL;DR
A pressure reducing valve is a spring-loaded plumbing valve installed near the water service entrance that throttles high municipal pressure down to a safe, adjustable level for the house. Model plumbing codes require one when street pressure exceeds 80 psi, with most homes set between 50 and 60.
What it means
A pressure reducing valve is a spring-loaded plumbing valve installed near the water service entrance that throttles high municipal pressure down to a safe, adjustable level for the house. Model plumbing codes require one when street pressure exceeds 80 psi, with most homes set between 50 and 60. Excess pressure hammers fixtures, bursts washer hoses, and shortens water heater life, so a failed unit often announces itself through banging pipes and dripping relief valves.
