Are you looking for a water pump for your property but need to know whether to choose a jet pump or a submersible pump? Well, it’s important to note that each type of pump has its own unique advantages and disadvantages, as they are specifically designed for different purposes.
One important factor is placement and depth, as submersibles are installed deep in the well while jet pumps are installed above ground. Operation and energy efficiency are also crucial, with submersibles generally being more efficient but jet pumps offering more control.
Here, we’ll take a closer look at the differences between the jet pump vs submersible, how they’re used, and which one may be better suited for your situation.
The Differences Between Jet Pump vs Submersible
A jet pump is a surface-mounted pump that pulls water from a well using suction and a series of impellers to increase the pressure. In contrast, submersible pumps use motors and impellers to push water from deep in a well up to the surface. Here are some key differences between them:
- No 01: Placement and Depth
- No 02: Operation and Energy Efficiency
- No 03: Installation and Complexity
- No 04: Priming and Noise
- No 05: Cost and Versatility
- No 06: Maintenance and Longevity
- No 07: Application and Reliability
- No 08: Service and Repair
- No 09: Debris Protection and Cooling Applications
- No 10: System Reservoir and Individual Needs
No 01: Placement and Depth
It’s essential to bear in mind the old adage “you don’t want to use a sledgehammer to crack a nut” means a lot when selecting the right pump for your well. It’s crucial to select one that is tailored to your well’s depth and requirements.
As a surface-mounted pump, the jet pump relies on suction pipes to draw water to the surface, making it the better option for shallow wells. Shallow well jet pumps can handle up to 25 feet, and deep wells can handle 100 feet.
Submersible pumps in deep wells between 50 to 150 feet provide greater force and efficiency because they push water to the surface more quickly.
No 02: Operation and Energy Efficiency
Jet pumps use suction and impellers to draw water from the well and create pressure. But they need a separate injector kit to create suction and can only operate at a particular depth.
On the other hand, submersible pumps use impellers to push water through piping and can be placed deep in the well to operate at a constant pressure. It makes them more energy-efficient, with up to 30% efficiency compared to jet pumps.
This results in lower energy costs and a reduced environmental impact, making submersible pumps a desirable option.
No 03: Installation and Complexity
There are multiple pipes and components to jet pumps, such as a suction pipe, a pressure pipe, and a foot valve. To regulate water pressure, you need to install a pressure tank.
In contrast, installing submersible pumps is a relatively simple process. All you need to do is install a single pipe, and the pump in the well will pump the water up through the pipe.
The simplicity of the installation process makes submersible pumps easy to set up, even for those with limited plumbing knowledge.
No 04: Priming and Noise
If you want a quiet pump without the hassle of priming, the submersible pump is the way to go. This pump requires no priming equipment or maintenance since it’s already submerged in the well. Not only that, but it operates much quieter due to being underwater.
In contrast, the jet pump must be primed before use, which can be time-consuming and require additional equipment. As it’s not submerged, it can produce more noise from the water flow and the vibration of the pump itself.
No 05: Cost and Versatility
Jet pumps are typically less expensive due to their simpler design and installation. Still, their limited flow versatility may require additional pumps or tanks to maintain water pressure, resulting in added costs.
Contrary to this, submersible pumps are known for their efficiency and ability to handle higher-demand water units. They can pump water from deeper depths and maintain consistent water pressure, making them more versatile.
While submersible pumps may have a higher upfront cost, their efficiency and versatility make them a more cost-effective option in the long run.
No 06: Maintenance and Longevity
Submersible pumps generally require less maintenance and have a longer lifespan than jet pumps. Here are some of the reasons why:
- As submersible pumps are submerged underwater, they are protected from dust, debris, and environmental factors.
- They have fewer moving parts than jet pumps, resulting in lower maintenance requirements and a longer lifespan.
- Submersible pumps are made from durable materials like stainless steel and cast iron, offering resistance to corrosion and harsh environments.
- They operate quietly, reducing noise pollution and creating a more comfortable environment for residential and commercial settings.
No 07: Application and Reliability
Jet pumps work well for smaller applications like wells and shallow groundwater but can’t handle larger volumes or deeper water levels. They won’t sustain damage if they run dry, making them great for areas with inconsistent water levels.
Submersible pumps are better for larger plumbing systems as they can handle deeper water levels and larger volumes. They’re more efficient, pushing water to higher elevations without losing pressure.
No 08: Service and Repair
The advantages of jet pumps include their above-ground placement and the ability to replace individual components easily and quickly. In comparison, submersible pumps may require full removal from the well for repairs, which can take more time and effort.
Submersible pumps are all-in-one units that do not require external components, but they may be more suitable for higher water flows and more output capacity.
No 09: Debris Protection and Cooling Applications
A trash basket is built into jet pumps to prevent debris from clogging the impeller and blocking water flow. This is especially useful if the water source is where debris builds up, such as in a river.
Also, jet pumps are ideal for cooling since they can move lots of water at lower head pressure, whereas submersible pumps are better for deep-well applications. Therefore, if you want a pump that is good at handling debris and for cooling, you should consider getting a jet pump.
No 10: System Reservoir and Individual Needs
When deciding on a water removal system, you should consider the limitations of the reservoir carefully. For those with a deep well needing a constant water supply, a submersible pump is ideal. These pumps can operate even when the water level is low and have a high capacity, making them perfect for continuous use.
On the other hand, for those with a shallow well or limited space for a sump, a better option may be a jet pump. These pumps are placed above ground and use suction to draw water up from the well. They are generally less expensive and require a smaller sump, making them affordable.

How Do You Use a Jet Pump with an Existing Plumbing System?
Using a jet pump with your existing plumbing system requires proper installation and connection to both the water source and the existing plumbing system. To ensure a successful installation, follow these steps:
i) Choose the right location for the jet pump. You want it to be near the water source and your existing plumbing system. This will minimize the distance that water needs to travel and increase the efficiency of your system.
ii) Connect the intake pipe of the jet pump to the water source. This may be a well or a water storage tank. Make sure the connection is secure and watertight. Any leaks could cause the system to lose pressure and reduce its efficiency.
iii) Connect the discharge pipe of the jet pump to your existing plumbing system. This connection should also be secure and watertight. You want to avoid any leaks or breaks in the pipe that could cause water damage or reduce your system’s efficiency.
iv) Once everything is connected, you must prime the jet pump according to the manufacturer’s instructions. This will remove any air from the system and ensure proper operation.
Can a submersible pump be used in a shallow well?
Submersible pumps are designed for use in deep wells where the water level is below the pump’s level. This type of pump is installed inside the well and submerged to push water up to the surface. But, they are not good for use in shallow wells where the water level is above the pump’s level.
In contrast, jet pumps are a better solution for these types of wells. Jet pumps use suction and are installed above ground to pull water from a well and push it up to the surface through a pipe.
Can a submersible pump run continuously without the risk of damage?
Running a submersible pump continuously without proper submersion in water can result in overheating and damage. If the water level drops below the pump’s intake, air can enter the system and cause the pump to run dry, leading to overheating and potential damage.
It is important to ensure the pump is always fully submerged in the water source, keeping it cool and lubricated.
Is a jet pump better than a submersible pump?
When it comes to pumping water from wells, jet pumps and submersible pumps are both popular choices. Thus, choosing the appropriate option depends on your requirements.
Jet pumps are usually cheaper and function well for shallow to moderate depths, but they become less effective as depth increases. Compared to submersible pumps, jet pumps produce more noise and require more maintenance.
Submersible pumps are more efficient than jet pumps at greater depths and tend to require less maintenance. These pumps operate quietly and efficiently. Nonetheless, they may be more expensive and require the assistance of a professional for installation.
A jet pump may be a cost-effective option if you have a shallow well. Whereas if you require reliable and effective water pumping from deep wells, then a submersible pump may be the better choice. Consider your specific needs and seek expert guidance to identify which option suits your situation.
Jet Pump or Submersible: Upgrade Your Well Water System
When picking a pump for your well, choosing the right one is paramount for a consistent and reliable water supply. While both jet and submersible pumps have their benefits, submersible pumps offer superior performance and ease of use.
Submersible pumps offer a low-maintenance, reliable, and constant water supply because they can handle greater well depths. And it operates continuously without overheating and is easy to install.
Choose a submersible pump to ensure the quality of your water supply and enjoy the peace of mind that comes with it. Your water supply deserves the best, and submersible pumps offer nothing less, choose wisely.
