How to Adjust a Water Pressure Reducing Valve (PRV) · Step 5 of 5
In this video
To set the water pressure, first use an adjustable wrench to loosen the locknut on the adjustment screw at the top of the regulator. Then, use a flathead screwdriver to turn the adjustment screw. Turning clockwise increases the pressure, and counter-clockwise decreases it. Use the pressure gauge on an outdoor spigot to monitor the pressure as you adjust it to your desired level, typically between 50 and 60 PSI.
Goal: Set the house water pressure to the desired level.

FAQs
How long does this project typically take, and is it really suitable for a DIY beginner?
Adjusting a PRV usually takes 30-60 minutes once you have the right tools and understand the steps. It is considered beginner-friendly as it primarily involves turning a bolt and monitoring a gauge. The main challenge is patience with incremental adjustments rather than complex plumbing skills.
Do I need a specific type of pressure gauge, or will any pressure gauge work for this project?
Yes, a specialized water pressure gauge that attaches to an outdoor spigot or washing machine hookup is essential for accurate readings. The Orbit Pressure Gauge 91130 or Water Source WSPGH100 are ideal for this. Using a generic or inaccurate gauge can lead to incorrect pressure settings, potentially damaging your plumbing.
What if I adjust the PRV but don't see any change in my water pressure?
If there's no change, first ensure your gauge is properly attached and functioning, and that you've loosened the locknut before turning the adjustment screw. The PRV itself might be faulty, clogged, or too old to respond to adjustments. In such cases, the PRV may need to be repaired or replaced by a professional plumber.
Are there any safety precautions I should take, or things I should absolutely avoid when adjusting the PRV?
Always make small, incremental adjustments (quarter turns at a time) to avoid sudden, drastic pressure changes that could stress your plumbing system. Never overtighten or force the adjustment screw, as this can damage the valve. Ensure the locknut is securely tightened after making adjustments to prevent the setting from drifting.
