Step 5 · Verify New Pressure
After making an adjustment, you must check the new pressure setting. To do this, you need to relieve the static pressure and allow the system to reset to the new setting. Go to a high-flow faucet inside the house, such as a bathtub, and turn on the cold water for about 30 seconds, then turn it off. This action allows the PRV to regulate the pressure to its new set point. Return to your pressure gauge on the outdoor bibb and read the new static pressure. Compare it to your target of 50-60 PSI. Repeat this step and the previous adjustment step as needed until you reach the desired pressure.
