What is a PRV and when does the District recommend their installation?

A pressure-reducing valve (PRV) reduces the water pressure to the customer. The Uniform Plumbing Code and the District recommend installing PRVs when the water pressure in the District’s mains exceeds 80 pounds per square inch (psi). The District will inform the applicant of this condition. PRVs are available at most hardware and plumbing stores, and are installed by the applicant on the applicant’s side of the water meter.
