Red Lion RJS-75-PREM 3/4 HP Shallow Well Jet Pump - Cast Iron

In this review of the Red Lion RJS-75-PREM shallow well jet pump, the bottom line is simple: it is aimed at homeowners, farmers, and cabin owners who need a rugged, cast-iron pump to deliver steady fresh water from shallow wells with lifts up to 25 ft. The single biggest reason to consider this pump is its durable construction and flexible motor wiring that supports either 115 or 230 volts, making it a practical choice when long service life and ease of matching site power are priorities.

Key Features

• Cast iron construction: The rugged cast iron casing and volute resist wear and provide a stable platform for long service life in rural or seasonal use.
• High flow capacity: With up to 16 gallons per minute, the pump supplies ample water for household fixtures or light irrigation without frequent cycling.
• Dual-voltage motor: The heavy duty motor is usable on either 115 or 230 volts and includes a capacitor for stronger starts, which simplifies installation across sites.
• Factory pressure switch: Ships with a pre-set 30/50 pressure switch and pressure gauge so the system reaches a typical working maximum of 50 PSI with minimal setup.
• Durable wear parts: Glass-filled thermoplastic impeller and diffuser reduce corrosion risk while maintaining efficiency in clean water service.
• Safety listing: CSA listing for USA and Canada gives added confidence for code-sensitive installations.

Who It's For

The Red Lion RJS-75-PREM is best for rural homeowners, small farms, and remote cabins that need a dependable shallow well solution and have suction lifts to about 25 ft. It suits buyers who value robust cast iron construction, a pre-set pressure switch, and the option to wire to common household voltages.

It is less appropriate for deep well applications, submersible well systems, or users who require ultra-quiet, brushless electronically controlled pumps for sensitive indoor installations. Those needing flow well above 16 GPM or specialized corrosion resistance should look at other pump types.

Pros & Cons

Pros

• Solid cast iron body and volute promise long-term durability in typical clean water use.
• Generous 16 GPM flow meets the needs of most homes and small farms without rapid cycling.
• Dual-voltage motor with included capacitor simplifies matching the pump to local power and helps starting torque.

Cons

• Some users report mixed long-term reliability of the motor; occasional failures have been noted in user feedback.
• Factory setting for 230 volts means installers must confirm and change voltage if 115 V is required, adding a step for some buyers.
