What is a Pressure Reducing Valve (PRV)?

Outside many of your homes, a pressure-reducing valve (PRV) regulates water pressure to safeguard your internal plumbing. Fitted to the water service line, the PRV regulates incoming water so that even if the supply pressure fluctuates, you only feel a constant flow of water at a functional pressure.

Building codes require PRVs for structures with water pressure at 80 psi and above. This PRV is owned and maintained by the homeowner.
