Quick Answer
A shallow well pump running continuously is often due to a combination of factors including low water levels, clogged screens, or an improperly set pressure switch, which can cause the pump to cycle excessively.
Common Causes of Continuous Pumping
A shallow well pump running continuously is often a sign of a larger issue. One common cause is a low water level in the well, which can cause the pump to cycle excessively as it struggles to find enough water to meet demand. Another common cause is a clogged screen, which can restrict water flow and cause the pump to work harder, leading to continuous operation.
Troubleshooting Techniques
To troubleshoot the issue, you can start by checking the water level in the well and adjusting the pump’s intake pipe as needed. If the water level is too low, you may need to install a deeper well or a backup water source. Next, inspect the screen for any blockages or debris and clean or replace it as necessary. You can also check the pressure switch to ensure it is set correctly and not causing the pump to cycle excessively.
Pressure Switch Adjustment and Settings
The pressure switch is a critical component of a shallow well pump system, and its settings can significantly impact the pump’s operation. To adjust the pressure switch, you’ll need to consult the manufacturer’s instructions and the pump’s settings chart. A general rule of thumb is to set the cut-in pressure (the pressure at which the pump starts to cycle) between 20-30 PSI and the cut-out pressure (the pressure at which the pump stops cycling) between 40-50 PSI. However, these settings may vary depending on the pump and well configuration, so it’s essential to consult the manufacturer’s instructions and make adjustments accordingly.
