How to Adjust a Water Pressure Reducing Valve (PRV) · Step 1 of 6
In this video
To ensure the expansion tank is properly pressurized, you must first determine your home's static water pressure. Screw a water pressure gauge onto an outdoor hose bib or spigot. Make sure no other water is being used in the house. Turn the spigot on fully, and read the pressure indicated on the gauge. This PSI reading is the target pressure for your expansion tank.
Goal: Determine the home's water pressure (PSI)

FAQs
Why is it important to adjust my water pressure reducing valve (PRV)?
Adjusting your PRV protects your home's plumbing, water heater, and appliances from damage caused by high water pressure, which can lead to leaks and premature wear. It also helps conserve water and reduces strain on your system, preventing costly repairs and ensuring efficient operation.
What is the ideal water pressure range for a home, and how do I know if mine is too high or too low?
Optimal household water pressure is generally between 40 and 60 PSI, with 50-55 PSI often considered ideal. Pressure consistently above 80 PSI is too high and can damage appliances and pipes, while below 40 PSI can cause poor shower performance and slow filling times.
What specific tools will I need to adjust my PRV, and is there one that's absolutely essential?
You'll primarily need a reliable water pressure test gauge, such as the Watts 3/4 in. Plastic Water Pressure Test Gauge, and an adjustable wrench. A screwdriver (flathead or Phillips, depending on your PRV model) may also be necessary for the adjustment screw. The pressure gauge is absolutely essential to accurately measure and verify your pressure.
How long should I expect this project to take, especially if I'm a beginner?
For a beginner, establishing baseline pressure, locating the PRV, and making the initial adjustment and re-test typically takes about 15-30 minutes. Allow a bit more time for any fine-tuning or if your PRV is difficult to access, as you may need to repeat the adjustment and test steps.
