Can You Use a Submersible Pump in a Shallow Well?

Choosing the Right Submersible Pump

When selecting a submersible pump for a shallow well, look for pumps with a high suction lift capacity. For example, a 1-inch submersible pump might have a suction lift capacity of up to 25 feet, while a 2-inch pump can handle up to 40 feet. This will help ensure the pump can handle the water level fluctuations in the shallow well.

Installation and Sizing Considerations

Proper installation and sizing of the submersible pump are crucial for efficient operation. To determine the correct pump size, calculate the well’s yield and the desired flow rate. For example, if the well produces 5 gallons per minute (gpm) and you need a flow rate of 2 gpm, a 1-inch pump would be sufficient. Additionally, consider using a pressure tank to regulate water pressure and prevent excessive wear on the pump.

Additional Factors to Consider

Another essential factor to consider is the pump’s head pressure and the well’s water level. If the well’s water level is consistently below the pump’s intake, it may not be able to prime itself, leading to reduced performance or failure. In such cases, installing a float switch or a pressure-activated valve can help ensure the pump’s intake remains submerged.
