Steps to Set Pressure Tank Air Charge
Preparation
Turn Off the Pump: Ensure the well pump is turned off to prevent water from entering the tank during the adjustment.
Drain the Tank: Completely drain the tank to remove all water. This can be done by opening a faucet in the house until the water stops flowing.
Adjusting the Air Pressure
Check the Pressure Switch Setting: Identify the cut-in pressure of your pressure switch. This is the pressure at which the pump turns on. Common settings are 30/50 psi or 40/60 psi.
Set the Air Charge: Adjust the air pressure in the tank to be 2 psi below the cut-in pressure. For example:
If the cut-in pressure is 40 psi, set the air charge to 38 psi.
If the cut-in pressure is 30 psi, set the air charge to 28 psi.
Final Steps
Recheck the Air Pressure: After adjusting, ensure the air pressure is correct using a pressure gauge.
Close the Drain Valve: Make sure the drain valve at the bottom of the tank is closed.
Turn the Pump Back On: Restore power to the pump and check for proper operation.
Important Notes
Always ensure there is a 20 psi difference between the cut-in and cut-off pressures to prevent rapid cycling of the pump.
Regularly check the air charge to maintain optimal performance of the pressure tank.
Steps to Adjust Water Pressure on a Well Pump
1. Safety First
Turn off the power to the well pump to ensure safety while making adjustments.
2. Locate the Pressure Switch
Find the pressure switch, which typically has two springs inside.
3. Adjusting the Pressure Settings
Cut-in and Cut-out Pressure:
To raise both the cut-in and cut-out pressures, turn the larger center spring nut clockwise.
To lower both pressures, turn the nut counterclockwise.
4. Set the Pressure Tank Air Charge
After adjusting the pressure switch, check the pressure tank air charge.
Set the air charge to 2 PSI below the new cut-in pressure to ensure optimal performance.
5. Final Checks
Once adjustments are made, restore power to the pump and monitor the system to ensure it operates correctly.
Important Considerations
Aspect Recommendation
Maximum Pressure Avoid exceeding 80 PSI to prevent damage.
Differential Setting Typically, maintain a 20 PSI differential between cut-in and cut-out pressures.
Monitoring Use a pressure gauge to verify changes during adjustments.
By following these steps, you can effectively adjust the water pressure on your well pump for better performance.
