The pressure in your house is usually adjusted using a pressure reducing valve (PRV) on your main water line. Here's how you can typically change it:
-
Locate the Pressure Reducing Valve (PRV): Find the PRV on your main water line, usually near where the water enters your house and after the main shut-off valve. It's typically a bell-shaped device.
-
Identify the Adjustment Screw: The PRV will have an adjustment screw or bolt, often on top.
-
Adjust the Pressure:
- To Increase Pressure: Turn the adjustment screw counter-clockwise.
- To Decrease Pressure: Turn the adjustment screw clockwise.
-
Make Small Adjustments: Make adjustments in small increments (e.g., quarter turns).
-
Check the Pressure: After each adjustment, check your water pressure using a water pressure gauge. You can attach one to an outdoor faucet or washing machine connection. Desired water pressure is typically between 40 and 60 PSI.
Important Considerations:
- Safety First: If you're uncomfortable making this adjustment yourself, consult a qualified plumber.
- Water Pressure Gauge: A water pressure gauge is essential for accurately setting the pressure.
- Consistent Pressure: Check the water pressure at different times of the day to ensure consistency.
- Consult a Professional: If you have very high water pressure, constantly fluctuating pressure, or are unsure about adjusting the PRV, consult a qualified plumber. Incorrect adjustments can damage your plumbing.
