The Short Answer on the RJS-100-PREM
Best for: you need a 1 HP shallow well pump with dual-voltage support and a 1-inch discharge for a household setup.
Choose the RJS-100-PREM if you want 23 GPM, 150 Ft of max head, and a listed price around $208.99.
- Pro: The 1 HP motor gives you the power level many household systems use for longer runs and more lift.
- Pro: Its 23 GPM maximum flow supports normal household demand and leaves room for several fixtures at once.
- Pro: Dual voltage, at 115 Volts or 230 Volts, gives you flexibility when matching incoming power.
- Con: The 150 Ft max head limits use in deeper wells, so a setup with greater lift demand is not a fit.
- Con: The 1-inch outlet can rule out systems built around a different discharge size, which means incompatible plumbing without changes.
Don’t buy this if: your well setup needs more than 150 Ft of lift or a discharge size other than 1 inch.
Price assessment: Around $208.99 is fair for a 1 HP pump with dual voltage and 23 GPM output.
Predicament Measures score: 7.3/10 (data-driven – see “How we picked” above)

Before You Buy: Well Pump Checklist
The first thing to check is your power source, because this pump is dual voltage and the listing states 115 Volts or 230 Volts. If your outlet or circuit does not match one of those, you will need different wiring before you can use it.
- ☐ Confirm your supply voltage — 115 Volts or 230 Volts; if your power does not match, you will be stuck with the wrong setup and extra electrical work.
- ☐ Measure your discharge plumbing — 1 FNPT outlet discharge; if your existing pipe or fittings are a different size, you will need adapters or replacement parts.
- ☐ Check the suction side connection — 1-1/4 FNPT suction intake; if your current well plumbing does not match, the pump will not tie in cleanly.
- ☐ Confirm the head your system needs — Max Head 150 Ft; if your well setup needs more lift, the pump may run without giving you usable pressure at the tap.
- ☐ Budget for a pressure-tank match — factory pre-set 30/50 pressure switch; if your tank or switch setup does not suit that range, you can end up with short cycling and early wear.
- ☐ Check the outlet size against your plumbing plan — 1 in discharge size; if your system is built around a different discharge size, you may have to rework the plumbing before the pump fits.
Do not buy this pump if you need a different voltage, a different outlet size, or more lift than 150 Ft.
Performance: What the Specs Deliver
How 23 GPM flow and pressure affect performance
RJS-100-PREM moves 23 GPM, so it suits a house that needs steady supply for several fixtures without chasing a larger flow figure. That rate is the number that matters for simultaneous demand, not the lift rating or the motor size. If your question is whether 23 GPM is enough for your house, sprinkler line, or shallow well setup, the answer is yes for lighter household demand and no for a setup that depends on higher delivery volume.
Its 150 Ft maximum head gives you a clearer ceiling on lift than the flow figure does. That matters when the well is deeper or the run is longer, because the pump can still move water upward through a substantial vertical rise. The 1-1/4 FNPT suction intake and 1 FNPT outlet discharge also tell you this is a shallow well pump with a 1-inch discharge path, so your piping and suction layout need to match those sizes before you order.
How dual-voltage setup matches available power
RJS-100-PREM runs on 115 Volts or 230 Volts, so you can match it to the power source already available at the site. That dual-voltage setup matters when you want one pump option for different electrical feeds, and the 17.6 Amps at 115 Volts versus 8.8 Amps at 230 Volts shows how the current draw changes with the supply you choose.
The voltage choice also affects how much margin you have on a small generator or stored-power system. At 1 HP, this pump sits in the range that can work for that kind of setup, but the incoming power has to be the right one for the feed you plan to use. The factory pre-set 30/50 pressure switch adds a fixed operating target, so you are buying a pump aimed at standard household pressure control rather than a custom-adjustable setup.
What cast-iron construction means for durability
RJS-100-PREM uses a cast iron casing and cast iron volute, which gives you a metal pump body instead of a plastic one. That matters for buyers who want a heavier-duty housing around the hydraulic parts, and the 39.5-pound weight reflects that material choice. The glass-filled thermoplastic impeller and diffuser keep the internal water-moving parts separate from the cast-iron shell.
The construction choice also explains what this pump is not: stainless steel construction is not stated, so you should not buy it for that material specifically. The CSA listing in the USA and Canada adds a compliance detail, while the 50 PSI working maximum pressure and 65 PSI maximum pressure cap the pressure side of the system. If you need a pump for a shallow well installation with standard household pressure, the cast-iron build and 1 HP motor make sense together; if you need a lighter body or a stainless housing, this is not that pump.
Common Buyer Jobs Checked Against the RJS-100-PREM’s Specs
The RJS-100-PREM against the jobs buyers ask about, worked out from its listed maximum head and maximum flow rate and horsepower and a typical need for each job.
| Job | What it takes | RJS-100-PREM |
|---|---|---|
| Pull water from a deeper well without losing usable pressure at the tap | at least 150 to 300ft | Only at the easier end of that range – 150ft |
| Keep up with a larger home using several fixtures at once | at least 15 to 25 GPM | Only at the easier end of that range – 23 GPM |
| Fit a 2-wire submersible setup without a separate control box | at least 0.5 to 1.5HP | Only at the easier end of that range – 1HP |
| Fit a 3-wire submersible setup with a control box | at least 0.75 to 2HP | Only at the easier end of that range – 1HP |
| Start and run from a small generator without overloading it | at least 0.5 to 1HP | Yes – 1HP |
How the RJS-100-PREM Compares to Other Well Pumps
When you need a 1 HP pump for a shallow well and want 1 in discharge sizing, the RJS-100-PREM gives you both for around $208.99. It also moves 23 GPM and is rated 4.1 from 1,429 buyers.
- WAYNE SWS100 matches the $208.99 price, but the Red Lion has the larger 23 GPM flow figure.
- RJC-75-PREM uses a 0.75 HP motor, so RJS-100-PREM has the stronger motor rating on that spec.
- CWS75 lists 90 feet of maximum head, while RJS-100-PREM states 150 Ft.
- Star SJ10 also uses a 1 HP motor, so horsepower is tied between the two.
- WAYNE CWS100 lists 3/4 in discharge size, while RJS-100-PREM uses a 1 in outlet.
If you want the strongest rating signal in this group, pick WAYNE CWS75 instead; it holds a 4.3 average, while RJS-100-PREM ranks third on ratings here.
What the deciding spec costs here: Measured as price per unit of horsepower, the reviewed product works out to $208.99 against a $219.98 median across the 101 other screened products that state the spec, and 43 of them deliver more of it per dollar. The cheapest screened product that beats its 1 HP is the LANCHEZ JGP11007WUINOX at $109.99 with 1.6 HP, which is $99 less than this one for more of the spec that decides this category.

From Delivery to First Use with This Well Pump
Power and fittings for RJS-100-PREM
RJS-100-PREM needs a 115-volt or 230-volt supply before it can move water.
- Confirm the incoming power source is 115 Volts or 230 Volts, because the pump is dual voltage.
- Match the outlet discharge to 1 FNPT, and keep the suction intake at 1-1/4 FNPT.
- Set the pressure switch to the factory preset 30/50 setting if that matches your system needs.
- Check that your plumbing can handle the 1-inch discharge size and the 50 PSI working maximum pressure.
- Verify the voltage selection before first start, since the motor draws 17.6 Amps at 115 Volts or 8.8 Amps at 230 Volts.
Warranty and support: what to check for RJS-100-PREM
Warranty cover differs by seller and country.
- Confirm the return window before it closes, because the 1 HP motor and cast iron casing are not small-ticket parts to replace.
- Confirm whether your seller treats the 115/230-volt selection as a return issue, since the pump must match the incoming power source.
- Confirm support for the 30/50 pressure switch setting, because the wrong switch setup can leave the system cycling badly.
- Confirm whether the 1-1/4 FNPT suction intake and 1 FNPT outlet discharge are covered for exchange, since a mismatch can block fitment.
On the day it arrives, verify the voltage option and the 1-1/4 FNPT and 1 FNPT fittings before the return window closes.
The RJS-100-PREM: Remaining Questions
Why the factory pressure switch suits a pressure tank
The factory 30/50 pressure switch suits a normal pressure tank setup, and the preset range is already stated on RJS-100-PREM. The working maximum pressure is 50 PSI, so the switch setting and tank should be chosen as a matched pair for the rest of the system.
For a cabin line that fills a small pressure tank and feeds a sink and shower, the preset switch gives you a defined starting point. The pressure gauge is included, which helps you confirm the system’s running range after the pump is selected.
Do I need to adjust the pressure switch on the Red Lion RJS-100-PREM?
No, the Red Lion RJS-100-PREM already ships with a factory-pre-set 30/50 pressure switch. That gives you a set starting range for a standard pressure tank arrangement.
If your tank or pressure needs differ, the switch setting becomes part of the compatibility check. The listing does not state any alternate switch range, so the preset is the only one named here.
Is the Red Lion RJS-100-PREM enough for a house with several fixtures?
The RJS-100-PREM is a 23 GPM pump, so it can support several fixtures when your demand stays within that flow range. That figure is the useful one for simultaneous use, not the 1 HP motor rating.
For a larger home, 23 GPM leaves less margin than a 25 gpm benchmark for multi-fixture demand. If your household draws heavily at once, you should compare your fixture count and peak flow need against that 23 GPM figure.
What does the 150 ft max head mean on the Red Lion RJS-100-PREM?
The 150 Ft max head means RJS-100-PREM can overcome that much vertical lift while moving water. That matters when the well is deeper or the run has more lift, because head measures lift rather than flow.
A shallow well with modest lift can fit that number well, while a deeper setup leaves less room for pressure loss. The listing also states a maximum lifting height of 25 feet, so the pump’s lift figures are not the same thing as usable flow at the tap.
What should I measure before buying the Red Lion RJS-100-PREM?
Measure your incoming power source, your discharge size, and your pressure-tank setup before ordering RJS-100-PREM. The pump is dual voltage at 115 Volts or 230 Volts, and it uses a 1 FNPT outlet discharge.
You should also confirm the well type, because this is a shallow well jet pump, not a submersible model. The 1-1/4 FNPT suction intake and cast iron body are part of the fit picture, while the voltage choice affects how you power it.

Is the RJS-100-PREM Right for You?
Who the RJS-100-PREM suits and the jobs it is the wrong choice for, listed below with the reason for each.
Who this well pump is for, and what it does well
Who the RJS-100-PREM suits
- Homeowners with a shallow well and standard household water pressure needs — the 1 HP motor, 23 GPM max flow, and 30/50 pressure switch fit typical small-home water supply setups
- Rural property owners replacing a shallow-well pump — the 25-foot maximum lifting height and 150-foot max head suit shallow well installations rather than deep wells
- Handy DIY installers wiring a dual-voltage pump — the 115/230V selectable motor and included capacitor make it practical for matching common residential power sources
- Small farm or workshop owners needing a cast-iron pump for regular water transfer — the cast iron casing and volute are suited to durable, fixed installations
- Maintenance techs servicing pressure tank systems — the built-in pressure gauge and factory preset 30/50 switch help with straightforward system setup and monitoring
- Amateur professional users doing light-duty water supply work — the 1-inch discharge, 1-1/4 FNPT suction, and 1 HP rating fit modest pump jobs without oversized equipment
What this well pump handles well
- Supplying water from a shallow well to a house — the 25-foot maximum lifting height and 150-foot max head support shallow-well service
- Pressurizing a small residential plumbing system — the factory preset 30/50 pressure switch and 50 PSI working maximum fit standard home pressure needs
- Moving water from a cistern or storage tank into a pressure tank — the 23 GPM maximum flow rate and 1 HP motor handle moderate transfer demand
- Irrigating a small yard or garden from a shallow water source — the 23 GPM max flow and 1-inch discharge support routine watering tasks
- Replacing an older shallow well jet pump in a utility room — the cast iron casing, cast iron volute, and compact 9.1 x 17.8 x 9.1 inch size suit fixed indoor pump installations
- Running a dual-voltage residential pump setup — the selectable 115V or 230V input supports common household electrical service
What this well pump is the wrong choice for
- High-volume irrigation for large fields — the 23 GPM maximum flow rate is too low for heavy agricultural watering
- High-pressure booster applications — the 50 PSI working maximum pressure limits it for stronger pressure-boosting jobs
- Large multi-bathroom homes with high simultaneous demand — the 1 HP motor and 23 GPM max flow may not keep up with bigger household loads
- Submersible well installations — the shallow well jet design and 1-1/4 FNPT suction intake are for above-ground shallow-well use, not submerged pumps
What to budget alongside this well pump, and what to skip
Accessories worth buying with the RJS-100-PREM
- Pressure tank — this pump is meant to work in a pressurized water system and the tank is not included
- Check valve — a shallow well jet setup typically needs backflow prevention to hold prime, and it is not listed in the box
- Piping and fittings — the 1-1/4 FNPT suction intake and 1 FNPT discharge require matched plumbing connections
- Electrical supply wiring — the corded electric pump needs proper 115V or 230V hookup matching the selected voltage
- Pump priming water — a jet pump needs priming before operation, and no priming water or priming kit is listed
Accessories you can skip buying for this well pump
- Submersible pump accessories — this is an above-ground shallow well jet pump, so submersible-specific parts are unnecessary
- Variable-speed controller — the factory preset 30/50 switch and fixed 1 HP motor make advanced speed control unnecessary here
- High-pressure booster accessories — the 50 PSI working maximum means extra booster hardware is usually wasted
- Large-capacity irrigation manifolds — the 23 GPM maximum flow does not justify oversized distribution hardware

Final Verdict on the RJS-100-PREM
You need a 1 HP shallow well pump with a 1-inch discharge and dual-voltage power, and the RJS-100-PREM fits that need at around $208.99. It also includes a factory-set 30/50 pressure switch and a pressure gauge, so you are not paying only for the motor rating.
Its 23 GPM flow rate is the strongest number here, and that is the figure that matters if you want one pump to support several fixtures without chasing a larger model. The 150 ft maximum head and 1-1/4 FNPT suction intake keep this squarely in shallow-well territory, so deeper wells need a different pick.
Skip it if: your well needs more than 150 ft of head, or you need flow closer to 25 gpm for heavier multi-fixture demand.
