The stainless steel housing resists corrosion, and the thermal overload protection prevents damage from dry running. Users report powerful performance and easy installation, with many praising the quiet operation.
Build quality is generally solid, but a few customers experienced cracks or leaks after 18-24 months. While Aquastrong’s warranty and customer service are highly rated, the motor is not sold separately, forcing full replacement. The included garden hose adapters and PTFE tape simplify hookup, though a check valve is recommended for best results.
Drawbacks are limited to long-term durability for some units, and the lack of a replaceable motor may frustrate those expecting modular repair. However, the pump’s performance and support team often offset these concerns.
Verdict: The Aquastrong shallow well pump offers excellent value for its power and automation. Ideal for homeowners needing a reliable booster for irrigation or light domestic use, but be aware of potential longevity issues. Strongly consider the warranty and responsive service when making your decision.

Using metal fittings instead of PVC is recommended to avoid leaks and prime loss.
While the pump itself is well-made, it lacks a pressure switch or tank, so you will need to purchase those separately for a complete pressure system. This may add to the overall cost and installation complexity. Despite these minor drawbacks, the pump offers excellent value for its price point and is a top seller in its category.
Overall, the AQUASTRONG 1.5 HP Shallow Well Jet Pump is a reliable, powerful choice for large-scale irrigation needs.

Before purchasing this pump, ensure your well depth is within the shallow well range (typically under 25 feet). This pump is not designed for deep wells. You will need a separate pressure tank and pressure switch if you want a fully automatic system for household water pressure.
For installation, use metal fittings (galvanized steel or brass) on both suction and discharge ports to prevent leaks and prime loss. PVC fittings may crack or fail under pressure. Apply pipe dope or Teflon tape to all threaded connections for a watertight seal.
If you experience prime loss, check all fittings for air leaks. The pump must be located as close to the water source as possible and installed with a foot valve or check valve to hold prime. Regular maintenance includes cleaning the impeller and checking for debris in the suction line.
Buying Guide
Horsepower and Flow Rate
Horsepower directly affects how much water a pump can move and how high it can push it. The Aquastrong 1.6 HP model delivers up to 1340 GPH with a maximum head of 164 feet, making it ideal for garden irrigation and domestic water supply. The 1.5 HP model, on the other hand, offers a massive 4250 GPH flow rate but a lower head of 108 feet. This makes it better suited for large lawns or sprinkler systems where volume matters more than height. Consider your well depth and water demand before choosing.
Build Material and Durability
The pump housing material determines how long the pump will last, especially in outdoor or corrosive environments. The 1.6 HP model features a stainless steel housing that resists rust and corrosion, perfect for areas with hard water or frequent moisture. The 1.5 HP model uses a durable cast iron volute, which is robust and long-lasting but heavier. Cast iron handles high pressure well, while stainless steel is lighter and more resistant to certain chemicals. Both are excellent choices, but your installation environment should guide the decision.
Automatic Features and Safety
Modern jet pumps come with automatic controls that save you time and protect the pump. The 1.6 HP model includes a pressure switch (20/40 psi) and a 5-gallon pressure tank, so it turns on and off automatically as you use water. It also has a temperature sensor that stops the motor if the pump runs dry, preventing overheating. The 1.5 HP model offers an automatic thermal overload protector that shuts down the pump if it gets too hot. Both models have waterproof on/off switches for safe operation. These features extend the pump’s life and reduce maintenance.
Voltage Flexibility
If you are wiring the pump into an existing electrical system, voltage compatibility is key. The 1.6 HP model runs on 115V, which is standard for most homes. The 1.5 HP model is dual voltage (115/230V) and comes factory set at 230V for higher efficiency. This flexibility allows you to adapt to different power supplies, especially in workshops or remote cabins. Always check your breaker capacity and wire gauge before installation.

Frequently Asked Questions
Can a convertible jet pump be used for a deep well?
Convertible jet pumps are designed for shallow wells up to 25 feet. For deeper wells, you need a submersible pump or a deep well jet pump with a two-pipe system. Always check the manufacturer’s specifications before installing.
Do I need a pressure tank with a jet pump?
Yes, a pressure tank is highly recommended because it prevents the pump from cycling on and off too frequently, which reduces wear and saves energy. The Aquastrong 1.6 HP model includes a compact 5-gallon tank, while the 1.5 HP model works with an external tank. Learn more about tank function in our article on how a well pressure tank works.
How often should I replace the pump seals?
With proper maintenance, the carbon ceramic mechanical seals in these Aquastrong pumps can last several years. Inspect them annually for leaks, especially if the pump runs frequently. Replace seals if you notice water dripping from the shaft area.
What is the difference between a jet pump and a centrifugal pump?
A jet pump uses a venturi to create suction and can lift water from a well, while a centrifugal pump relies on an impeller and is typically used for boosting pressure from a tank or municipal supply. The Aquastrong 1.5 HP model is a combination pump that works as both a jet pump for shallow wells and a centrifugal booster pump for irrigation.
