Came to the customer’s home to diagnose improper water pressure. Upon arrival, tested the incoming pressure and the gauge read 120 PSI, which is significantly above the safe recommended range. Inspected the main water line and confirmed that no Pressure Reducing Valve (PRV) is installed. Recommended installing a Pressure Reducing Valve (PRV) to regulate the home’s water pressure. Provided an estimate of $595.00 for the PRV installation.
