A PRV is an adjustable mechanical device designed to keep water pressure between 25 and 75 pounds per square inch (psi).
The Universal Plumbing Code (UPC) recommends to use a PRV if your water pressure is 80 pounds per square inch (psi) or higher.
The Universal Plumbing Code (UPC) minimum is 20 pounds per square inch (psi).
The district has lots of hills and valleys if you are at the top of a hill you might have lower water pressure, if you are in a valley you could have higher pressure. These areas are referred to as pressure zones.
