Turning up a water pressure valve involves adjusting the screw on the pressure reducing valve (PRV) to increase the water pressure in your home. Here's how to do it:
-
Locate the Pressure Reducing Valve (PRV): The PRV is typically located where the main water line enters your house. It's often near the water meter.
-
Identify the Adjustment Screw: The PRV has an adjustment screw, usually located on top. It's often covered by a cap. Remove the cap if present.
-
Loosen the Lock Nut (If Applicable): Some PRVs have a lock nut that secures the adjustment screw. Use a crescent wrench to loosen this lock nut by about half a turn. You don't need to remove it completely.
-
Increase the Pressure: Turn the adjustment screw clockwise to increase the water pressure. Make small adjustments, usually no more than one full revolution at a time.
-
Check the Pressure Gauge: After each adjustment, check your water pressure using a pressure gauge. You can attach a pressure gauge to an outside faucet or a washing machine hose connection.
-
Monitor and Adjust: Monitor the water pressure and make further adjustments as needed. Aim for a pressure between 40 and 60 PSI. Do not exceed 80 PSI, as high water pressure can damage your plumbing and appliances.
-
Tighten the Lock Nut (If Applicable): Once you've reached the desired pressure, tighten the lock nut to secure the adjustment screw.
Important Considerations:
- Start Small: Always make small adjustments to avoid over-pressurizing your system.
- Monitor Pressure: Regularly check your water pressure after making adjustments to ensure it remains within a safe range.
- Consult a Professional: If you're unsure about any part of this process, or if you're unable to adjust the valve, contact a qualified plumber.
- Pressure Gauge: Essential for accurately measuring water pressure. They can be purchased at most hardware stores.
- Safety First: High water pressure can damage your plumbing. Do not exceed recommended pressure levels.
