If your home relies on well water, the pump you choose makes all the difference in maintaining a steady, reliable water supply. Two of the most common types are submersible pumps and jet pumps. Both serve the same purpose—moving water from your well to your home—but they do so in very different ways. Understanding the differences will help you decide which option best fits your household’s needs, especially if you’re looking to replace your broken well pump.
What Is a Submersible Well Pump?
As the name suggests, submersible pumps are installed inside the well and submerged below the water level. They use a motor and impeller to push water upward directly into your plumbing system.
Advantages:
- Highly efficient since they push water rather than pull it.
- Typically quieter because the pump is underwater.
- Longer lifespan when properly maintained, often 10–15 years.
- Ideal for deep wells exceeding 25 feet.
Disadvantages:
- More difficult and costly to service since they must be pulled from the well.
- Installation costs can be higher.
What Is a Jet Well Pump?
Jet pumps are installed above ground, usually in a basement or utility room. They work by creating suction to draw water up from the well. Shallow-well jet pumps can handle depths up to 25 feet, while deep-well jet pumps can draw from depths of 100 feet or more using a two-pipe system.
Advantages:
- Easier and less expensive to service since they’re above ground.
- More affordable upfront compared to submersible pumps.
- Versatile, working for both shallow and moderately deep wells.
Disadvantages:
- Less efficient than submersible pumps, especially at greater depths.
- Louder operation since the pump is not submerged.
- May require priming if air enters the system.
Which Pump Is Right for You?
- Choose a submersible pump if your well is deep, you want maximum efficiency, and you don’t mind investing more upfront for long-term reliability.
- Choose a jet pump if your well is shallow or moderately deep, you want easier access for maintenance, and you’re looking for a more budget-friendly solution.
Both submersible and jet well pumps offer dependable ways to supply your home with water, but the right choice depends on your well depth, budget, and maintenance preferences. If your current system is failing, take time to assess your options carefully before you replace it. By choosing the right pump, you’ll ensure a steady water supply for years to come.
