Shallow Well Jet Pump 1 HP 23 GPM - Premium Cast Iron

In this review the Red Lion RJS-100-PREM is evaluated as a practical, heavy-duty shallow well jet pump for rural homes, farms, and cabins that need reliable fresh water delivery. The bottom line: it is best for buyers who want a rugged, serviceable pump with a 1 HP motor capable of delivering up to 23 gallons per minute and who can ensure the pump is wired to the correct voltage. The strongest reason to consider it is the cast iron construction and included factory pre-set 30/50 pressure switch that make it ready for typical shallow well installations.

Key Features

• 1 HP motor: Provides up to 23 GPM which is sufficient for household supply and small irrigation tasks without excessive cycling.
• Dual voltage motor: The heavy duty motor can run on either 115 or 230 volts, allowing flexibility for different power sources when wired correctly.
• Rugged cast iron body: Cast iron casing and volute deliver long life and durability for outdoor or utility use.
• Factory pressure control: The included pre-set 30/50 pressure switch and gauge make start-up and system control straightforward for most shallow well systems.
• Durable hydraulics: Glass-filled thermoplastic impeller and diffuser resist wear while keeping the unit cost-effective to own.
• Safety and compliance: CSA listing for USA and Canada gives buyers confidence in certified construction and motor safety.

Who It's For

The RJS-100-PREM suits property owners with wells that have a suction lift down to around 25 ft who need a dependable pump for everyday water supply. Its 1-in discharge and 1-1/4-in suction fittings match common plumbing on rural homes, gardens, and small-scale livestock watering systems.

It is not ideal for deep wells or larger commercial systems that require higher head or continuous heavy-duty pumping; those users should look for deeper well jet pumps or submersibles with higher head ratings and larger flow capacity.
