If you’re getting a new water pump, a key question to ask yourself is whether a submersible or a jet pump will best suit your needs. A jet pump lies above ground using suction to pull water from a shallow well, while a submersible pump is placed underwater and then pushes water up to the surface. This works better for deeper wells.
There are several factors to consider besides simply replacing what you already have. These factors include your well depth, budget and long-term water needs. Here we will take a look at each option and learn how to figure out which is best for you.
What Is a Well Pump?
Well pumps are needed in homes that have private wells. A well pump is a system that pulls water from an underground well and sends it to your home. The two main types are jet pumps and submersible pumps.
Pumps can move water through either sucking it up or pushing it out. This depends on the type of pump you have.
How Jet Pumps Work
Jet pumps are installed above the ground and use suction to complete their job. These are called single-pipe pumps. They draw water from shallow wells but work up to 120 feet deep. Jet pumps are easier to maintain due to where they are located, but are less efficient in deeper wells.
How Submersible Pumps Work
Submersible pumps are usually best for deeper wells (400 feet or more). They lie completely underwater and use impellers that spin and pull fluid through an intake. This pushes it through diffusers and then up and out of a discharge pipe. While submersible pumps are efficient and quiet, they can be harder to fix.
Jet Pump vs. Submersible Pumps Work
While jet and submersible pumps both serve the same purpose, they are installed and operate in different ways.
Installation & Well Depth
Jet pumps function well in wells that aren’t too deep or shallow. Submersible pumps are best for medium to deeper wells.
Efficiency & Performance
Submersible pumps are usually more energy-efficient since they push water from greater depths, which takes less energy to do. Jet pumps are better for shallow wells, but use more energy. Submersible pumps work better than jet pumps for wells that are deeper.
Cost & Maintenance
Jet pumps are cheaper to buy and easier to fix because of where they are. Submersible pumps are initially more expensive. However, since they are underwater, they don’t wear out as quickly, saving money in the long run.
Durability & Lifespan
On average, jet pumps will last between 10 and 15 years. Submersible pumps usually last between 15 and 25 years.
Noise Levels
Jet pumps operate above ground and utilize suction to work. This makes noise from the motor and the water circulation. Submersible pumps, on the other hand, are underwater, dampening the sound and making them much quieter.
Cost Breakdown: Jet vs. Submersible Pumps
According to This Old House, the average cost of installing a well pump ranges from a hundred to thousands of dollars. The price will depend on how deep the well is, what kind of pump you have, where you live, your yard’s layout and the tools needed for installation. The price of a well pump is usually between $200 and $500 – not including labor.
Submersible pumps usually save more energy in the long run. Although they cost more to fix, they are generally stronger than jet pumps and don’t need as much upkeep.
Choosing the Right Pump for Your Well
You need to think about a few things before you can pick the proper pump for your well. This includes the amount of water you use, the soil on your property and the depth of your well.
You also need to determine which choice is best for your budget. Jet pumps are cheaper to install, but over time, they can be expensive to keep up. At first, submersibles cost more, but they are more efficient long-term.
Pros and Cons: Jet vs. Submersible Pumps
| Category | Jet Pump | Submersible Pump |
|---|---|---|
| Ideal Depth / Placement | Shallow to moderate wells (≈ up to 120 ft). Installed above ground for easy access. | Medium to deep wells (≈ 120–400+ ft). Installed underwater inside the well casing. |
| Efficiency & Performance | Works well in shallow wells but uses more energy as depth increases. | Typically more energy-efficient, pushes water upward from depth with less energy loss. |
| Upfront Cost | Usually lower purchase & install cost. | Higher initial equipment & installation cost. |
| Maintenance & Repairs | Easier/cheaper to service since it’s above ground. | Harder/more expensive to repair—must be pulled from the well. |
| Durability & Lifespan | Avg lifespan ~10–15 years. | Avg lifespan ~15–25 years; fewer wear issues, better long-term reliability. |
| Noise | Louder (motor and water movement are above ground). | Quieter—motor is underwater and noise is dampened. |
| Best For | ✔Shallow wells ✔Lower upfront budget ✔Easy access/quick maintenance | ✔Deeper wells ✔Higher efficiency & pressure ✔Long-term reliability |

| Quick Verdict | Pick Jet if you have a shallow well, want lower upfront cost, and prefer easy servicing. | Pick Submersible if you have a deeper well and want efficiency, quiet operation, and longevity. |
FAQs About Jet and Submersible Well Pumps
Which pump is better for deep wells?
Submersible pumps work better for deeper wells. Their location underwater allows them to efficiently push water up to the surface. Their design offers better energy efficiency, quieter operation, greater water pressure and a longer life span.
Are submersible pumps more expensive to repair?
Yes, while they are more durable than jet pumps, they are more expensive to repair. For repairs to be completed, they must be pulled from the well, which requires specialized tools, labor and expertise.
How do I know if my well needs a jet or submersible pump?
The best way to determine what kind of pump you need is to check your well’s depth, your family’s water usage and your long-term efficiency goals.
Do submersible pumps last longer than jet pumps?
In general, yes, they do. Usually, submersible pumps last between 15 and 25 years, while jet pumps last between 10 and 15 years.
Let Us Help You Choose the Right Well Pump
If your well is shallow, your water demand is more limited and you require easy access, a jet pump may be your best solution. However, if you want something that’s energy-efficient and offers greater power and long-term reliability for a deeper well, a submersible pump is probably the way to go. It’s also important to consider your overall budget when making your final selection.
