Not every well pump serves the same purpose, especially in Arizona. With water tables often reaching depths of 300 to 400 feet, most systems rely on submersible pumps to bring water to the surface.
That said, jet pumps still show up in certain setups. While they are not the primary solution for most Arizona wells, they can play a role depending on how your system is designed.
How a Jet Pump Works
A jet pump is installed above ground and works by pulling water up through suction rather than pushing it from below.
Here is the basic process:
- Water is drawn into the system through a suction pipe
- A motor drives an impeller, which moves water through the pump
- The ejector assembly creates a pressure difference that helps pull water upward
- The system delivers water into your plumbing or storage system
Unlike submersible pumps, jet pumps must be primed before they can operate. If the pump loses its prime, it will stop working until it is refilled and restarted.
When It Might Be Time to Check Your Jet Pump
Jet pumps tend to show clear warning signs before they fail completely.
Here are common signs your jet pump may need service or replacement:
- Loss of prime or difficulty maintaining suction
- Low or inconsistent water pressure
- The pump runs continuously without building pressure
- Air sputtering through faucets
- Unusual noise coming from the pump
Because these pumps rely on suction, even small leaks or system issues can affect performance.
Advantages of Jet Pumps
Jet pumps are still used today because they offer a few practical benefits in the right situations.
Lower Installation Cost
Jet pumps are generally more affordable upfront compared to other pump types, making them appealing for budget-conscious installations.
Above-Ground Accessibility
Since the pump is not located inside the well, repairs and maintenance are easier and less labor-intensive.
Simple System Design
The design is straightforward, which can make troubleshooting and servicing more manageable.
Limitations of Jet Pumps
In Arizona water systems, the limitations of jet pumps matter more than their advantages.
Not Suitable for Deep Wells
Jet pumps struggle to pull water from significant depths. With Arizona wells often reaching hundreds of feet, they are not practical for primary water extraction.
Requires Priming
If the pump loses prime, it stops working. This adds an extra layer of maintenance that other pump types do not require.
Lower Pressure Output
Jet pumps typically cannot generate the same level of pressure as submersible or centrifugal pumps.
Higher Operating Costs
Because they work against gravity to pull water upward, jet pumps tend to be less energy-efficient over time.
Noisy Operation
Since the pump is above ground, it is more noticeable during operation compared to submersible systems.
When a Jet Pump Makes Sense
Jet pumps are not the standard well pump choice in Arizona, but they can still be useful in specific situations.
They are most commonly used for:
- Shallow wells where water is close to the surface
- Older systems that were originally designed around jet pump technology
- Basic or low-demand water systems
- Occasional use applications where high pressure is not critical
In some cases, they may also be used alongside storage systems, though other pump types are often more efficient for that role.
Other Concerns When Designing a Well Water System
Choosing the right pump is only part of the equation. The entire system needs to work together.
Here are a few key factors to consider:
Well Depth
This is one of the biggest factors in Arizona. Deep wells typically require submersible pumps rather than jet pumps.
Flow Rate Requirements
Your household and irrigation needs determine how much water the system must deliver at any given time.
Pressure Needs
Consistent pressure is critical for daily use. Some systems may require booster pumps to maintain performance.
System Design
Your well, storage tank, and pump must be properly matched. Even a good pump will struggle in a poorly designed system.
