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.
Yes, if the well casing is wide enough to accept a submersible pump (typically 4 inches or more) and deep enough to justify it. This usually requires a well contractor to re-pipe the wellhead and run new wiring, so it's a bigger job than a simple pump swap, but it's a common upgrade when a shallow well's jet pump reaches end of life.
Often yes, even under 25 feet — submersible pumps are quieter, more efficient, and self-priming, so some homeowners choose one even when a jet pump would technically work. The main tradeoff is a harder, more expensive repair if it ever needs to be pulled from the well.
Submersible pumps typically last longer (10-15 years vs 8-12 for jet pumps) because they run cooler and don't fight suction lift, but jet pumps are far easier and cheaper to diagnose and repair when something does go wrong, since everything is accessible above ground.
No, not effectively — standard jet pumps lose the ability to lift water reliably much beyond 100 feet of total lift, even with a deep-well jet configuration. Wells deeper than that need a submersible pump, which pushes water from below rather than pulling it up from the surface.
