Buying Guide: What to Look for in a Deep Well Jet Pump
Choosing the best jet pump for a deep well involves several key factors. We have evaluated these two models based on the following criteria that matter most to homeowners and small farm operators.
Convertible vs. Dedicated Deep Well Design
Not all jet pumps can handle deep wells. A convertible jet pump, like both the Goulds J5 and the Acquaer, can be set up for either shallow (single pipe) or deep (two pipe) applications. This flexibility is essential if you plan to use the pump for different well depths or if you may move to a new property later. The Goulds J5 is specifically designed for deep wells up to 140 feet with the proper ejector kit, while the Acquaer covers depths from 26 to 90 feet. Make sure the pump you choose matches your well’s total depth. For more on sizing related components, read our guide on well pressure tank sizing.
Horsepower and Flow Rate
Horsepower directly affects how much water the pump can move. The Goulds J5 is a 1/2 HP motor, suitable for typical household demands with depths up to 140 feet. The Acquaer features a 1 HP motor, offering higher flow and stronger suction, which can be beneficial for larger homes or irrigation needs. However, more horsepower does not always mean better efficiency; it depends on your well’s yield and pressure requirements. Both pumps are rated for continuous operation, ensuring they can handle extended use without overheating.
Build Quality and Corrosion Resistance
Well water often contains minerals and abrasives that can wear down a pump over time. The Goulds J5 uses a glass-filled Noryl impeller and a Lexan diffuser with a stainless steel wear ring, providing excellent corrosion and abrasion resistance. Its electro-coat paint and protected mechanical seal further enhance durability. The Acquaer has a rugged cast iron volute that is built to last, but its internal components are not as extensively detailed. If you have hard water or sandy conditions, the Goulds may offer a longer service life.
Ease of Installation and Maintenance
Both pumps are convertible, but installation complexity varies. The Goulds features a back pullout design that allows you to service the pump without disturbing the piping, and its O-ring fittings only need hand tightening. The Acquaer includes an ejector kit and venturis, and its automatic pressure switch is preset at 20/40 PSI, making it simpler to set up for basic applications. For advanced installation tips, refer to our well pumps category page for more resources.
Final Thoughts
After evaluating these two models, we recommend the Goulds J5 Convertible Jet, Deep Well Pump for buyers who prioritize long-term durability and superior corrosion resistance, especially in abrasive water conditions. Its continuous-duty motor and serviceable design make it a workhorse for deep wells up to 140 feet. For those on a tighter budget or with shallower deep wells, the Acquaer Shallow/Deep Well Jet Pump offers strong performance with a 1 HP motor and cast iron construction at a fraction of the cost. Both are excellent choices, but your well depth and water quality will ultimately guide your decision.
Frequently Asked Questions
What is the difference between a shallow well and deep well jet pump?
A shallow well jet pump uses a single pipe and is limited to depths of about 25 feet. A deep well jet pump uses two pipes and an ejector to lift water from depths greater than 25 feet, typically up to 90 feet or more with proper equipment. The Goulds J5 and Acquaer are both convertible, meaning they can be configured for either type.
How deep can a jet pump draw water?
With a standard two-pipe setup, a deep well jet pump can lift water from depths of up to 90 feet for the Acquaer and up to 140 feet for the Goulds J5, given the appropriate ejector kit. Actual performance depends on the well’s static water level and the pump’s horsepower. For deeper wells, a submersible pump may be needed.
Can I use a jet pump for both shallow and deep wells?
Yes, convertible jet pumps like the ones we reviewed are designed for both applications. They come with the necessary fittings to switch between shallow (single pipe) and deep (two pipe) configurations. Make sure to select the correct ejector kit for your well depth.
Do I need a pressure tank with a jet pump?
Most jet pumps are paired with a pressure tank to maintain consistent water pressure and reduce cycling. The pressure switch on these pumps (30–50 PSI for the Goulds, 20–40 PSI for the Acquaer) signals the pump to start and stop. For more details, see our article on pressure systems.
