Quick Answer
A submersible pump in a deep well should be installed at a depth of around 20-30 feet below the water table. This allows for optimal water flow and prevents air intake, which can damage the pump. A depth of 20-30 feet also prevents the pump from being too deep, making it harder to repair or replace.
Choosing the Right Depth for Your Submersible Pump
When deciding on the ideal depth for your submersible pump, you need to consider several factors, including the well’s diameter, the pump’s size, and the water table’s elevation. A general rule of thumb is to install the pump at a depth of 20-30 feet below the water table. This depth range allows for optimal water flow and prevents air intake, which can damage the pump.
Factors Affecting Pump Depth
Several factors can affect the optimal depth for your submersible pump, including the well’s diameter and the pump’s size. A larger well diameter requires a deeper pump installation to take advantage of the increased water flow. Conversely, a smaller pump may require a shallower installation to avoid oversizing. Additionally, the water table’s elevation and the surrounding geology can impact the optimal pump depth.
Installing the Pump at the Right Depth
To install the pump at the right depth, you’ll need to determine the water table’s elevation and the well’s diameter. Use a well casing extension and a submersible pump that’s specifically designed for deep well installations. The pump should be installed at a depth of around 20-30 feet below the water table, taking into account the well’s diameter and the pump’s size. This will ensure optimal water flow and prevent air intake, extending the pump’s lifespan and overall performance.
