Star JHU10 1 HP Cast Iron Convertible Jet Pump for Shallow or Deep Wells, Made in the USA using a Majority of U.S. Content

Dependable water delivery for residential setups starts with a convertible jet well pump designed to handle changing source depths. The Star JHU10 is built to draw water across two distinct setups: single-pipe shallow wells with suction lifts between 0 and 25 feet, or dual-pipe deep well installations reaching down as far as 110 feet. Its heavy cast iron casing houses a 1 HP motor, providing the necessary strength to sustain consistent domestic water flow.

Driving the system is a continuous-duty uni-frame 56 motor that operates on either 115 or 230 volts. It features a capacitor start mechanism to deliver strong starting torque, ensuring the pump starts smoothly even under load. For added peace of mind during extended operation, integrated thermal overload protection guards the electrical windings from overheating damage, while the NEMA J adaptable design offers standard mounting flexibility.

Day-to-day operation and regular maintenance are addressed directly through the hardware choices. The unit includes a carbon/ceramic mechanical shaft seal to preserve a tight barrier around the rotating components. When it is time to get the system running, a special priming port allows for direct water filling to speed up startup. In regions exposed to freezing conditions, an easily accessible drain plug simplifies the task of emptying the pump body for seasonal winterizing.

Because this pump covers both shallow and deep configurations, it arrives without a few application-specific parts. While it comes with the pump, motor, pressure switch, pressure regulator body, and flow control screw, you will need to supply the ejector and a pressure gauge on your own. Selecting the correct external ejector depends on your exact well depth and configuration, meaning this is not a completely plug-and-play package right out of the crate.

Verdict: The Star JHU10 is a solid pick for homeowners or property managers needing a resilient, dual-voltage convertible jet well pump capable of servicing wells up to 110 feet deep. If you want a complete all-in-one kit that includes the ejector and monitoring gauge straight out of the box, you may want to look elsewhere.

A great fit if you:

• Need a durable cast iron pump that can be set up for a shallow well under 25 feet or a deep well down to 110 feet.
• Have either 115-volt or 230-volt electrical service available and want the flexibility of a dual-voltage capacitor-start motor.
• Live in an area that experiences freezing weather and need an accessible drain plug for quick winterization.

Consider something else if you:

• Want a self-contained installation package that already includes the ejector assembly and a pressure gauge in the box.
• Have a deep well setup with suction lifts that exceed 110 feet, requiring a higher-capacity deep well unit.

Confirm on the listing:

• Check your exact well depth and confirm your pipe setup is single pipe (up to 25 feet) or dual pipe (up to 110 feet).
• Review the capacity charts on the listing to identify which specific ejector model matches your required pumping performance.
• Check whether you have an existing pressure gauge on hand or need to order a new gauge alongside the pump.
• Confirm whether your installation wiring will supply 115 volts or 230 volts so you can configure the motor properly.

How to compare your options: When evaluating convertible jet pumps, match the required suction lift and horsepower rating to your water source depth. The Star JHU10 offers 1 HP of power across single-pipe shallow setups and dual-pipe deep configurations. It also includes key mechanical pieces like the pressure switch and regulator body, but you should factor in the separate acquisition of the ejector and gauge when comparing overall project requirements.

Take advantage of the special priming port whenever setting up the pump for initial use or re-priming after service. Filling the casing completely through this port helps avoid running the carbon and ceramic mechanical shaft seal dry, supporting smooth operation from the first start.

If you live in a climate where freezing temperatures are common during cold seasons, make use of the accessible drain plug. Draining all standing water from the cast iron housing before the onset of winter helps protect the cast iron body from freeze damage.

Verify your electrical connections match your chosen voltage supply, whether you are running on 115 volts or 230 volts. The continuous-duty motor includes thermal overload protection, but ensuring correct wiring alignment upfront allows the capacitor start system to deliver maximum torque reliably.

Does this pump come with an ejector included?
No, the ejector is not included in the package and must be ordered separately based on your specific well depth and capacity needs.

What well depths can this pump handle?
It supports single-pipe shallow well installations with suction lifts from 0 to 25 feet, as well as dual-pipe deep well setups with suction lifts up to 110 feet.

What electrical voltage does the motor require?
It features a dual-voltage motor designed to run on either 115 volts or 230 volts, allowing you to connect it to your existing service.

Is a pressure gauge included in the package?
No, the pressure gauge must be ordered separately along with your ejector, though the pressure switch and regulator body are included.

What warranty coverage is provided with this unit?
It is 100% factory tested and backed by a Star Water Systems 2-year limited warranty.
