It's important to clarify that you don't directly increase the pressure meter itself. The water pressure meter (or gauge) simply displays the current water pressure. To increase water pressure, you would adjust the pressure-reducing valve (PRV) on your main water supply line, if you have one.
Here's how you might be able to increase the water pressure, assuming you have a PRV:
Locating and Adjusting the Pressure Reducing Valve (PRV)
The pressure-reducing valve (PRV) is typically located on the main water supply pipe where it enters your home, often near the water meter.
Steps to Adjust the PRV:
-
Identify the PRV: Look for a bell-shaped or conical valve on the main water line. It will have a bolt extending from the cone and a locknut on that bolt.
-
Locate the Pressure Gauge: Find a pressure gauge installed on your plumbing, typically near the PRV or on an appliance like a washing machine. If you don't have one, you may need to install one to accurately monitor the pressure.
-
Loosen the Locknut: Using a wrench, loosen the locknut located on the bolt of the PRV.
-
Adjust the Bolt (Clockwise to Increase): Turn the bolt clockwise to increase the water pressure. Make small adjustments and check the pressure gauge after each adjustment.
-
Monitor the Pressure Gauge: Observe the pressure gauge to determine when you reach the desired water pressure. A typical residential water pressure is between 40 and 60 PSI (pounds per square inch). Do not exceed the recommended pressure for your plumbing system, as this can damage pipes and appliances.
-
Tighten the Locknut: Once the desired pressure is achieved, tighten the locknut to secure the bolt and maintain the setting.
Important Considerations:
- Safety First: Always exercise caution when working with plumbing.
- Water Hammer: Increasing water pressure can sometimes exacerbate water hammer (a banging noise in the pipes when water flow is suddenly stopped). If this occurs, you may need to install water hammer arrestors.
- Local Codes: Be aware of local plumbing codes regarding water pressure.
- Professional Assistance: If you are not comfortable making these adjustments yourself, consult a qualified plumber. They can accurately assess your system and make the necessary adjustments safely and effectively.
- Pressure Too High: High water pressure can damage appliances, cause leaks, and shorten the lifespan of your plumbing system. Be mindful of this when adjusting the PRV.
- No PRV: If you don't have a PRV, you can't easily adjust the pressure. The pressure coming into your house is determined by the municipal water supply. Contact your water company if you suspect issues.
- Low Pressure Issues: Low pressure might not be solved by adjusting the PRV, as it might be due to other issues like clogged pipes, partially closed valves, or problems with the main water supply.
By carefully adjusting the pressure-reducing valve (if present), you can influence the water pressure in your home. Remember to monitor the pressure gauge and stay within safe pressure limits to protect your plumbing system.
