The question "How do you adjust a water pressure gauge?" is slightly misleading, as you don't typically adjust the gauge itself. Instead, you adjust the water pressure regulator (also known as a pressure reducing valve or PRV) while monitoring the water pressure using a gauge. The adjustment alters the pressure of the water flowing through your plumbing system.
Here's how to adjust your water pressure, based on the provided reference:
Steps to Adjust Water Pressure
The adjustment is made on the pressure reducing valve (PRV), and you'll need to observe your water pressure gauge while making adjustments.
-
Locate the Pressure Reducing Valve (PRV): This is typically a bell-shaped valve found where the main water line enters your house.
-
Locate the Adjustment Nut/Screw: On the PRV, you'll find a nut or screw that allows you to adjust the spring tension inside the valve.
-
Monitor the Water Pressure Gauge: Observe the gauge to see the current water pressure. It's important to know your starting point.
-
Adjust the Nut/Screw:
-
Increase Pressure: Turn the adjustment nut/screw to the right (clockwise) to increase the water pressure.
-
Decrease Pressure: Turn the adjustment nut/screw to the left (counter-clockwise) to decrease the water pressure.
-
-
Make Small Adjustments: Adjust the nut or screw in small increments and check the gauge after each adjustment. This prevents over-pressurizing your system.
-
Target Pressure: A typical recommended water pressure is around 50-60 PSI (pounds per square inch). Check local codes for specific requirements.
Important Notes:
- If the PRV is old, it may not adjust properly and might need replacement.
- After adjusting, run water in a few fixtures to allow the system to stabilize.
