A valve that reduces high water pressure from the street to a safe level for the building's pipes and fixtures.
A valve that automatically reduces and stabilizes the incoming water pressure from the utility supply to a safe operating level for building plumbing systems. Most codes require a pressure reducing valve (PRV) when street pressure exceeds 80 PSI. PRVs protect fixtures, water heaters, and appliances from damage caused by high pressure.
With street pressure measured at 110 PSI, the plumber installed a PRV set to 65 PSI to protect the plumbing system.
