Arrived on site and customer stated they were experiencing high water pressure throughout the house. I took a pressure reading of the house pressure, and got a reading of 110. I explained that the pressure should be no higher than 80 psi and recommend replacing the PRV. Customer agreed to have the regulator replaced , so I cut out the regulator , as well as put in a new ball valve for the main shut off. Once regulator was set in place, I adjusted the regulator to 65 psi.
