Adjusting a pressure reducing valve typically involves locating the adjustment screw, loosening the lock nut (if present), turning the screw to increase or decrease pressure, and then tightening the lock nut to secure the setting.
Here's a more detailed breakdown of the process:
Steps to Adjust a Pressure Reducing Valve
-
Locate the Pressure Reducing Valve: The valve is usually located where the main water line enters your house, often near the water meter. It usually has a bell-shaped body.
-
Identify the Adjustment Screw: Look for a screw or bolt on top of the valve, often covered by a cap. This is the adjustment screw. There is usually a lock nut associated with the screw.
-
Check Your Current Water Pressure (Optional): Before making any adjustments, it's a good idea to check your current water pressure using a pressure gauge connected to an outdoor faucet or washing machine connection. This gives you a baseline to work from. Target pressure is generally between 40 and 60 PSI.
-
Loosen the Lock Nut: If there's a lock nut securing the adjustment screw, loosen it with a wrench. This allows you to turn the screw.
-
Adjust the Pressure:
- To Increase Pressure: Turn the adjustment screw clockwise.
- To Decrease Pressure: Turn the adjustment screw counterclockwise.
Make small adjustments and check the pressure gauge after each adjustment to avoid over-pressurizing your system.
-
Check the Pressure: After each adjustment, check the water pressure using your gauge. Allow the water to run briefly to get an accurate reading.
-
Tighten the Lock Nut: Once you've reached the desired pressure, tighten the lock nut to secure the adjustment screw in place.
-
Test and Monitor: Monitor your water pressure for a few days to ensure it remains stable at the desired level.
Important Considerations
- Safety First: Always exercise caution when working with plumbing. If you're uncomfortable making adjustments yourself, consult a qualified plumber.
- Gradual Adjustments: Make small adjustments at a time to prevent over-pressurizing your plumbing system.
- Refer to Manufacturer's Instructions: Consult the manufacturer's instructions for your specific pressure reducing valve model, as adjustment procedures may vary slightly. Watts is a common manufacturer, and their website (watts.com) may offer helpful information.
- Avoid Excessive Pressure: Do not set the water pressure too high, as this can damage your plumbing fixtures and appliances. Generally, a pressure between 40 and 60 PSI is recommended.
By following these steps, you can effectively adjust your pressure reducing valve and maintain a safe and comfortable water pressure in your home.
