To increase water pressure using a pressure reducing valve (PRV), tighten the adjustment screw on the valve by turning it clockwise.
Here's a more detailed explanation:
Most pressure reducing valves have an adjustment screw located on the top or side. This screw controls the internal spring tension within the valve, which directly affects the downstream water pressure.
-
Locate the Adjustment Screw: Identify the adjustment screw on your pressure reducing valve. It's usually covered by a cap or locknut.
-
Loosen the Locknut (if applicable): If there's a locknut, loosen it to allow the adjustment screw to turn freely.
-
Adjust the Screw Clockwise: Slowly turn the adjustment screw clockwise. This increases the spring tension and, consequently, the downstream water pressure.
-
Monitor the Pressure: Use a pressure gauge connected to a nearby faucet or fixture to monitor the water pressure as you make adjustments. This is crucial to avoid over-pressurizing your plumbing system. A typical residential water pressure range is between 40 and 60 PSI.
-
Tighten the Locknut (if applicable): Once you've achieved the desired water pressure, tighten the locknut to secure the adjustment screw and prevent it from changing.
Important Considerations:
- Do Not Exceed Recommended Pressure: Never exceed the maximum pressure rating of your plumbing system or appliances. This can cause leaks, damage, or even bursts. Consult the specifications of your plumbing fixtures and appliances to determine their pressure limits.
- Small Adjustments: Make small adjustments to the screw and check the pressure after each adjustment.
- Stuck Valves: If the valve is old or corroded, the adjustment screw may be stuck. Do not force it, as this could damage the valve. Consider replacing the valve if necessary.
- Professional Assistance: If you are unsure about adjusting the pressure reducing valve, consult a qualified plumber.
In summary, adjusting water pressure with a pressure reducing valve involves turning the adjustment screw clockwise to increase the pressure, all while carefully monitoring the pressure gauge and ensuring you do not exceed safe pressure limits.
