Turning a water pressure regulator screw clockwise increases the water pressure.
Here's a more detailed explanation:
When you adjust a water pressure regulator, you're essentially changing the tension on an internal spring. This spring controls how much the valve inside the regulator opens, which, in turn, determines the water pressure allowed to flow through.
-
Clockwise (Tightening): Turning the adjustment screw clockwise tightens the spring. This requires more water pressure to overcome the spring's resistance and open the valve. As a result, the output water pressure increases.
-
Counterclockwise (Loosening): Turning the adjustment screw counterclockwise loosens the spring. This makes it easier for the water pressure to open the valve. Consequently, the output water pressure decreases.
In summary:
| Direction | Effect | Pressure Change |
|---|---|---|
| Clockwise | Tightens Spring | Increases |
| Counterclockwise | Loosens Spring | Decreases |
Always adjust the regulator in small increments and check the water pressure with a gauge after each adjustment to avoid over-pressurizing your plumbing system.
