Types of well pump: which one fits your well?
Choose Submersible pump for a well casing at least 4 inches in diameter (some submersible pumps fit wells 3 inches in diameter); Shallow-well jet pump for water less than 25 feet below the surface; Deep-well jet pump for water 25 to 250 feet below the surface.
The right choice depends on how far below the surface the water is, the diameter of the well casing, and whether the pump can sit where it needs no frost protection.
| Type | Best for | Main advantages | Main drawbacks |
|---|---|---|---|
| Submersible pump | a well casing at least 4 inches in diameter (some submersible pumps fit wells 3 inches in diameter) | does not need frost protection, since it is located below the frost line; quiet, per Connecticut Department of Public Health well conference slides (2018) | if repairs are needed, the pump must be pulled from the well |
| Shallow-well jet pump | water less than 25 feet below the surface | sits above ground, so it is easy to access for repairs; can be located a distance from the well | requires frost protection; must be primed (filled with water) when first started; noisy compared to a submersible, per Connecticut Department of Public Health well conference slides (2018) |
| Deep-well jet pump | water 25 to 250 feet below the surface | may be used in wells that are 3 inches or less in diameter; the pump can be located a distance from the well | the jet sits in the well and must be removed from the well for service; jet pumps typically give less operating pressure and less water yield than submersible pumps |
