Quick Answer
Yes, it's possible to switch from a shallow well pump to a submersible pump later, but you'll need to consider factors like well depth, pump installation costs, and potential electrical upgrades.
Assessing Well Depth and Pump Installation
When deciding whether to switch to a submersible pump, check your well’s depth and the pump’s installation requirements. Typically, submersible pumps are suitable for wells with depths between 20 and 500 feet. If your well is shallow (less than 20 feet), a shallow well jet pump or a submersible pump specifically designed for shallow wells might be a better option. Consider hiring a professional to assess your well’s depth and determine the best pump configuration.
Electrical Upgrades and Pump Power Requirements
Submersible pumps typically require more power than shallow well pumps, especially for deeper wells. You may need to upgrade your electrical system to accommodate the increased power requirements. A general rule of thumb is to ensure your electrical system can handle at least 1 horsepower (HP) per 10-15 feet of well depth. For example, a well with a 100-foot depth would require a 6-10 HP pump. If your electrical system can’t support the increased power, you may need to upgrade your electrical panel, wiring, and possibly even your generator.
Cost Considerations and Potential Upgrades
When switching to a submersible pump, consider the installation costs, which can range from $1,000 to $5,000 or more, depending on the well depth and pump configuration. Additionally, you may need to upgrade your well casing or screen to accommodate the submersible pump’s installation requirements. A professional well driller or pump installer can help you determine the best course of action and provide a detailed estimate for the necessary upgrades and installation costs.
