Adjusting the pressure on your water main typically involves adjusting the water pressure regulator on your property, not the main municipal water line. Adjusting the pressure on the municipal water main itself is the responsibility of the water utility company.
Here's how to adjust your water pressure regulator:
Steps to Adjust Your Water Pressure Regulator
-
Locate the Water Meter: The water meter is usually found where the water line enters your house, often in the basement. It's typically near the supply line.
-
Find the Water Pressure Regulator: The regulator is usually a bell-shaped device located on the water line after the water meter. It often has a screw or bolt on top.
-
Loosen the Locknut: At the base of the adjusting screw, you'll usually find a locknut. Use a wrench to loosen this locknut. This will allow you to turn the adjusting screw freely.
-
Turn the Screw to Adjust the Pressure:
- To increase the water pressure, turn the adjusting screw clockwise.
- To decrease the water pressure, turn the adjusting screw counter-clockwise.
Make small adjustments and check the water pressure after each adjustment using a water pressure gauge. This will help you avoid over-pressurizing your system. Attach the gauge to an outside faucet or a washing machine hose connection to get an accurate reading. Ideal water pressure is usually between 40 and 60 PSI (pounds per square inch).
-
Retighten the Locknut: Once you've reached the desired water pressure, tighten the locknut to secure the adjusting screw in place. This will prevent the pressure from changing unintentionally.
Important Considerations
- Water Utility Responsibility: If you're experiencing consistently low or high water pressure issues affecting multiple properties, contact your local water utility company. They are responsible for maintaining the pressure on the main water lines.
- Safety First: If you are uncomfortable making these adjustments yourself, contact a licensed plumber. Improper adjustments can damage your plumbing system.
- Pressure Gauge is Essential: Always use a water pressure gauge to monitor the pressure while making adjustments.
- Building Codes: Local building codes may dictate allowable pressure ranges. Adhere to these guidelines.
- Constant Pressure: The water pressure regulator ensures constant pressure in the water pipe.
