Understanding pressure reducing valves, how they work, when you need one, installation, and maintenance.
A pressure reducing valve (PRV) is a plumbing device that reduces high water pressure coming from the mains supply to a safe, manageable level for your home's plumbing system.
If your water pressure is too high, it can damage pipes, appliances, and fixtures. A pressure reducing valve protects your plumbing by limiting the pressure to a safe level, typically around 3-4 bar (45-60 psi).
