How to Adjust a Water Pressure Reducing Valve (PRV) · Step 1 of 6
In this video
To adjust the reduced pressure, first loosen the outer locknut on top of the valve. Turn the adjustment bolt clockwise to raise the pressure or counterclockwise to lower the pressure. Watch the downstream pressure gauge to reach the desired setting. For best results, allow a trickle of water to flow from a fixture during adjustment. Once set, tighten the locknut to secure the adjustment bolt.
Goal: Plumbing Fixture Repair
- Do not bottom out the adjustment bolt against the bell housing when raising pressure.
- Flow a trickle of water from a downstream fixture while adjusting for greater accuracy.

FAQs
Why is it important to use a water pressure gauge for this project?
A water pressure gauge is crucial because it provides an accurate reading of your home's current water pressure. Without it, you cannot precisely determine if your pressure is too high or too low, making proper adjustment impossible. It ensures you meet the recommended 50-60 PSI range and helps prevent damage to your plumbing system.
What are the potential risks if I don't adjust my water pressure to the recommended range?
Ignoring incorrect water pressure can lead to significant problems. High pressure can cause pipes to burst, damage expensive appliances like water heaters and dishwashers, and wear out faucets prematurely. Low pressure, conversely, can lead to frustratingly weak showers and slow filling times for fixtures, impacting daily comfort and efficiency.
How long does it typically take to adjust a PRV, and is it truly a beginner-friendly DIY task?
Adjusting a PRV usually takes 15-30 minutes, especially if the valve is easily accessible. This project is considered beginner-friendly because it primarily involves locating the valve, using a simple pressure gauge, and making small, controlled adjustments with basic tools. Patience and incremental changes are key to success.
My water pressure isn't changing after I've turned the adjustment screw. What could be the issue?
First, ensure the locknut on the PRV is fully loosened before attempting to turn the adjustment screw. If the pressure still doesn't change after several turns in either direction, the PRV itself might be faulty or stuck. In such cases, the valve may need to be repaired or replaced by a professional plumber.
