You can change water pressure by adjusting the pressure-reducing valve (PRV).
Here's a step-by-step guide, incorporating information from the provided reference:
Adjusting the Pressure Reducing Valve (PRV)
The PRV is typically located near your main water shut-off valve. This valve regulates the water pressure entering your home. Here's how to adjust it:
- Locate the PRV: Find the PRV, which is usually situated near the main water shut-off valve.
- Find the Adjustment Screw: Look for an adjustment screw on the top of the valve.
- Adjust the Screw:
- To increase the water pressure, turn the screw clockwise.
- To decrease the water pressure, turn the screw counter-clockwise.
- Test the Pressure: After making a small adjustment, check the water pressure in your house to see if it meets your desired level.
- Repeat as Needed: Continue to adjust the screw and test the water pressure until you reach the desired level.
Important Considerations
- Minor adjustments are key. Avoid making large adjustments at once, as this could lead to over-pressurization or other problems.
- If Adjustments Don't Help: According to the provided reference, if adjusting the screw doesn't change the water pressure, or if the valve appears damaged, you should consider replacing the valve.
- Professional Help: If you are unsure about adjusting the PRV yourself, it's best to contact a qualified plumber for assistance.
Additional Factors
While adjusting the PRV is the most common way to change water pressure in your home, other factors might influence it, such as:
- City Water Pressure: The pressure coming from the city's water supply can affect what you experience in your home.
- Pipe Issues: Leaks or blockages in your home's plumbing can reduce water pressure.
- Fixture Issues: Problems with individual faucets or showerheads can also make it seem like the pressure is low.
In summary, changing water pressure often involves adjusting the PRV, but it's important to be aware of other potential causes of pressure issues.
