A complete comparison of submersible and jet pumps — cost, depth limits, efficiency, lifespan, and which one makes sense for your well.
A submersible pump sits inside the well casing, submerged in water. It pushes water up to the surface. A jet pump sits above ground and pulls water up using suction. That single difference determines which type works for your well depth.
💡 Simple rule: Well under 25 feet deep = jet pump possible. Well over 25 feet = submersible pump required.
| Feature | Submersible Pump | Jet Pump |
|---|---|---|
| Max well depth | 400+ feet | 25 ft (shallow) / 100 ft (deep jet) |
| Pump location | Inside well casing | Above ground |
| Efficiency | Higher — pushes water | Lower — pulls water |
| Noise | Silent (underground) | Audible motor noise |
| Purchase cost | $150–$800 | $100–$500 |
| Installation cost | $400–$1,200+ | $200–$500 |
| DIY replacement | Difficult | Manageable |
| Lifespan | 10–15 years | 8–12 years |
| Maintenance access | Must pull from well | Easy above-ground access |
If your well is under 25 feet deep, a shallow well jet pump is a simple, affordable option. If your well is 25–100 feet deep, you can use a deep well jet pump or a submersible — submersible is generally recommended for better efficiency. If your well is over 100 feet deep, a submersible pump is your only practical option.
For most modern residential wells drilled in the last 30 years, the well is deeper than 100 feet and a submersible pump is standard.
