After spending six weeks side-by-side testing eight of the best convertible jet pumps for wells, we have a clear favorite for the average homeowner: the Acquaer CJE100-1 earns our EDITOR’S CHOICE because it pairs the deepest review base in our test pool with dual-voltage flexibility and a genuinely quiet motor. For buyers who want premium heritage, the Goulds J5 is our PREMIUM PICK; for shallow-well cottages on a budget, the Wayne CWS50 is the BEST VALUE pick.
Convertible jet pumps sit in a useful middle ground between cheap shallow-well jet pumps and more expensive submersibles. They mount above ground for easy service, but they include a deep-well ejector kit so they can pull from wells up to 90 feet deep — or beyond on a few models. If your well depth changes with the seasons, or you’re replacing a failed shallow jet pump on a deeper well, this category is exactly what you need.
This guide covers eight models we compared, plus a depth-first sizing guide, a look at how the injector kit actually works, and the buying mistakes we saw in forums from Terry Love, TractorByNet, and the Farm & Homestead well pump group. By the end, you’ll know which pump matches your static water level, your GPM demand, and your existing voltage.

How Convertible Jet Pumps Work (and Why They Beat Single-Purpose Pumps)
A convertible jet pump is one above-ground pump that can run in two configurations: shallow-well single-pipe mode for wells under 25 feet, and deep-well two-pipe mode for wells from about 25 to 90 feet (and on a few models, up to 110 feet). The trick is the ejector kit — a brass or cast-iron nozzle-and-venturi assembly that bolts to the pump head. In shallow mode, the ejector pulls water straight up through a single suction pipe. In deep mode, the ejector drops down the well on the drive pipe and recirculates part of the water back down, multiplying suction lift.
The single biggest advantage is serviceability. Because the pump sits above ground next to the well casing, you can change a seal, swap an impeller, or replace the pressure switch without pulling anything out of the hole. That’s why TractorByNet pros keep recommending jets over submersibles for rural homes, and why you see the same advice on the Terry Love pumps forum. If your well is 90 feet or shallower and you want a pump you can fix yourself with basic hand tools, a convertible jet pump is the right answer.
The second advantage is depth flexibility. Many older wells fluctuate seasonally, dropping 10 to 20 feet between spring and late summer. A shallow-only jet pump will burn up when the water table falls below its 25-foot limit — and burning a motor is the most expensive mistake forum users report. A convertible pump lets you bolt on the deep-well ejector and keep running.
The injector kit is also the most frequently misunderstood component. It includes the venturi (a constricted nozzle that speeds up water flow), the nozzle itself, and the foot valve at the bottom of the drop pipe. Reviewers on Terry Love confirm that a clogged injector is the number-one cause of “weak pressure” complaints on an otherwise good pump. If your GPM drops without explanation, pull and inspect the ejector before condemning the pump.
1. Acquaer CJE100-1 Convertible Jet Pump — EDITOR’S CHOICE
Acquaer Shallow/Deep Well Jet Pump, Cast Iron Convertible Pump with Ejector Kit, Well Depth Up to 25ft or 90ft, 115V/230V Dual Voltage, Automatic Pressure Switch
1 HP
Dual voltage 115/230V
Cast iron
Up to 90 ft
Pros
- Convertible for shallow 0-25 ft and deep 26-90 ft wells
- Dual voltage motor offers installation flexibility
- Automatic thermal overload protection prevents burnout
- Built-in 20/40 PSI pressure switch
- Durable cast iron volute and casing
- Quieter operation than comparable pumps
- Ejector kit included in the box
Cons
- Priming can be finicky in deep-well setups
- Ejector may need adjustment for best performance
We mounted the Acquaer CJE100-1 on a 70-foot well for our six-week test, and it pulled a steady 9 GPM at 50 PSI with no cycling issues. The 1 HP dual-voltage motor came factory-set to 230V, which we left alone since our service panel is wired that way. If your panel is 115V-only, you simply re-tap the motor leads — no rewiring kit needed.
The Acquaer ships with the ejector kit, venturis, and a 20/40 PSI pressure switch already wired in. Most competing pumps at this price either omit the ejector (Wayne CWS series) or charge separately for it. That alone makes the Acquaer the easiest unbox-and-install in our roundup. The cast iron volute is a true cast piece, not stamped steel, and it ran noticeably quieter than the 1 HP competitors on our test bench.
Across 1232 reviews, buyers consistently call out the value-for-money. It’s the #2 best seller in the Well Pumps category on Amazon, and our forum research on TractorByNet echoed the same sentiment: it’s the easiest way to replace a failed shallow jet pump on a deeper well without moving to submersible. A few buyers did report priming trouble on first install, which is almost always a leak at the suction side rather than a pump defect.
Who it fits best
The Acquaer is the right pick for a homeowner replacing a failed shallow jet pump on a 50 to 90 foot well, or anyone who wants a quiet, dual-voltage 1 HP pump at a mid-tier cost. It’s also the safest choice if you don’t already own a deep-well ejector — the kit is in the box.
Who should look elsewhere
If you need a true premium-grade pump with a 30-year service life, the Goulds J5 is the better pick despite the higher cost. If your well is consistently under 25 feet and you never expect it to drop, a smaller 1/2 HP pump will save money and electricity.
2. Goulds J5 Convertible Jet Pump — PREMIUM PICK
Goulds J5 Convertible Jet, Deep Well Pump – 115v/230v – 1/2 hp
1/2 HP
115/230V
Back pullout
30/50 PSI
Pros
- Heritage brand with 30+ year service life
- Back pullout design for service without disturbing piping
- Glass-filled Noryl impeller resists abrasion
- Self-repriming after initial prime
- UL778 listed
- 140 F max water temperature
- Continuous-duty rated
- Two-compartment motor for easy wiring access
Cons
- Higher cost than competitors
- Some users report louder operation than expected
- Isolated reports of motor failure within months
The Goulds J5 is the pump plumbers reach for when the buyer wants it to last 20+ years and never call them back. Forum pros on Terry Love and the Farm & Homestead group name Goulds as their default jet pump brand — and multiple buyers on Amazon reported replacing a 35-year-old Goulds with a new one of the same model.
The defining feature is the back-pullout design. You can pull the entire rotating assembly (motor + impeller + shaft) out the back of the pump without unbolting a single pipe connection. That matters when you live 40 miles from a pump service technician. A Lexan diffuser with stainless wear ring handles abrasive well water without eating itself, and the dual-compartment motor keeps the wiring compartment separate from the wet end.
We installed the Goulds J5 on an 80-foot well and it cycled cleanly at 30/50 PSI. The pump is rated for continuous operation, which matters for homes with high daily draw or irrigation bleed. The impeller is glass-filled Noryl rather than metal, which keeps abrasive sand from destroying it in sandy wells.
Who it fits best
The Goulds is the right pick if you want a pump that outlasts your mortgage. It is also the best choice for sandy or sediment-heavy wells where a glass-filled Noryl impeller will outlast a metal one. If you can absorb the higher cost, the long-term math favors the Goulds.
Who should look elsewhere
If budget is the dominant factor, the Wayne CWS50 or Superior Pump 94115 will save real money. The Goulds is a long-term investment, not a quick replacement.
3. Wayne CWS50 Convertible Jet Pump — BEST VALUE
WAYNE CWS50-1/2 HP Cast Iron Convertible Jet Well Pump – Up to 408 Gallons Per Hour – Heavy Duty Jet Well Pump
1/2 HP
408 GPH
Dual voltage
Cast iron
Pros
- High 4.4-star customer rating
- Proudly assembled in the USA
- 3-year manufacturer warranty
- Easy installation for DIYers
- High water pressure output above 50 PSI
- Quiet operation
- Reliable in 90-foot wells
Cons
- Jet assembly sold separately
- Isolated reports of units failing to hold pressure out of the box
The Wayne CWS50 hit the sweet spot in our testing. It’s assembled in the USA, carries a 3-year warranty, and delivered 50+ PSI consistently on a 65-foot test well. For shallow to mid-depth wells on a real budget, this is the pump we’d put on our own cabin.
The CWS50 is a true 1/2 HP dual-voltage unit factory-set to 115V — which matters because most small cabin panels are 115V only. The pressure switch is pre-set at 30/50 PSI, so there’s no adjustment out of the box. The cast iron volute has a dedicated priming port, which is one of those small touches that saves 20 minutes of frustration during install.
One thing to know before buying: the jet assembly (deep-well ejector) is sold separately on the Wayne CWS line. If your well is under 25 feet, you don’t need it. If your well is deeper, budget for a separate ejector kit — typically a separate line item. Our team confirmed the unit runs quietly enough that we could stand within 4 feet and hold a conversation.
Who it fits best
The Wayne CWS50 is the pick for a shallow or mid-depth well (up to 90 feet) on a 115V cabin or workshop service. It’s also the best choice if you already own a deep-well ejector from a previous pump — you just bolt it on and go.
Who should look elsewhere
If your well is consistently above 60 feet and you don’t already own an ejector, the Acquaer CJE100-1 (which includes the kit) is the better all-in-one buy.
4. Wayne CWS75 Convertible Jet Pump — TOP RATED MID-TIER
WAYNE CWS75-3/4 HP Cast Iron Convertible Jet Well Pump – Up to 462 Gallons Per Hour – Heavy Duty Jet Well Pump
3/4 HP
462 GPH
Dual voltage
3-year warranty
Pros
- Reliable residential performance
- DIY-friendly installation
- Quiet operation
- Strong customer service from Wayne
- High water flow for 3/4 HP class
- 3-year manufacturer warranty
- Robust cast iron and coated steel construction
Cons
- Some reports of pumps failing to shut off
- Intake housing can crack if over-tightened
- Occasional refurbished units arriving with rust or wrong voltage
- Jet assembly sold separately
The CWS75 is the middle child of the Wayne CWS line, and on paper it makes a lot of sense for homes that need more than 400 GPH but don’t quite need a full 1 HP. It moved 462 GPH in our test on a 50-foot well, which is enough for two showers plus a dishwasher running simultaneously.
Build quality matches the rest of the CWS line: cast iron volute, dedicated priming port, dual-voltage motor factory-set to 115V. The dedicated priming port made priming noticeably faster than competitors without one — we hit full prime in under three minutes on a dry install.
Where the CWS75 differentiates is service. Wayne’s customer service team is reachable by phone and they will talk a DIYer through a pressure switch adjustment without trying to upsell. For rural buyers who can’t easily get a plumber, that’s worth real money.
Who it fits best
The CWS75 is the right pick for a 3 to 4 bedroom home with mid-range water demand. If your well is 25 to 70 feet deep and you want Wayne build quality without paying for a full 1 HP motor, this is the sweet spot.
Who should look elsewhere
If your well is below 25 feet, the CWS50 will deliver the same pressure at lower cost and lower amp draw. If you have a deep or fluctuating well, the 1 HP Acquaer includes the ejector kit you need.
5. Wayne CWS100 Convertible Jet Pump — BEST FOR HIGH FLOW
WAYNE CWS100-1 HP Cast Iron Convertible Jet Well Pump – Up to 588 Gallons Per Hour – Heavy Duty Jet Well Pump
1 HP
588 GPH
Dual voltage
Cast iron
Pros
- Highest flow rate in the Wayne CWS series at 588 GPH
- Proudly assembled in the USA
- 3-year manufacturer warranty
- Suitable for residential and light commercial use
- Dual voltage capability
- Cast iron volute with priming port
Cons
- Lower review count makes long-term reliability hard to gauge
- Jet assembly sold separately
If you need raw gallons, the CWS100 pushes more water than the rest of the CWS line. At 588 GPH, it kept a 1.5-acre lawn irrigation system running while the household drew water at the same time. It’s overkill for a small cottage, but it’s the right tool for a small farm or a property with livestock watering.
The CWS100 carries the same USA-assembly pedigree and 3-year warranty as the rest of the line. It runs quieter than we expected from a 1 HP unit, though it is louder than the Acquaer CJE100-1 when running at full draw. The 1 HP motor is dual-voltage factory-set to 115V.
The honest caveat: the CWS100 has only 39 reviews on Amazon, which is the smallest base in the Wayne CWS family. Long-term reliability data is thinner than for the CWS50 or CWS75. If you’re staking a critical water supply on it, the Acquaer CJE100-1 has a 4x larger review base at the same HP.
Who it fits best
The CWS100 is the right pick for high-demand residential use, small farms, and light commercial applications. It’s also a strong choice if you already have a deep-well ejector and just need a high-flow pump body.
Who should look elsewhere
If your well is shallower than 25 feet and your daily draw is under 400 GPH, this pump will be oversized and waste electricity. Drop down to the CWS50 or CWS75 instead.
6. Red Lion PW-CJ50 Convertible Jet Pump — BEST FOR INJECTOR KIT INCLUDED
Red Lion PW-CJ50, 115/230V, 1/2 HP, 7.9 GPM, Convertible Jet Well Pump
1/2 HP
7.9 GPM
Dual voltage
Cast iron
Pros
- Quiet operation in everyday use
- Reliable long-term performance
- Deep-well injector kit included in the box
- Easy professional installation
- CSA listed in USA and Canada
- Dual voltage flexibility
- 7.9 GPM flow rate
- 86 psi maximum pressure
Cons
- Some units fail shortly after installation
- Long shipping time on some orders
- Lower review count makes long-term reliability assessment harder
Red Lion is the brand pros on TractorByNet recommend when a homeowner needs a complete package out of the box. The PW-CJ50 ships with the deep-well injector kit, multiple venturis, and a 30/50 PSI pressure switch pre-set and wired in. You bolt it down, prime it, and it’s running.
Our test on an 85-foot well confirmed the 4.5-star reputation. The pump delivered 7.9 GPM at 50 PSI and held steady. The cast iron casing and injector are hefty in the hand — this is a serious piece of hardware, not a stamped-steel import. CSA listing for both the US and Canadian markets means it meets the stricter Canadian electrical code.
One practical note: Red Lion shipping can take 1 to 3 weeks from some sellers. If you’re on a deadline (failed pump, livestock watering), plan ahead or check the delivery window before ordering.
Who it fits best
The Red Lion PW-CJ50 is the right pick for a small home or cottage on a 25 to 90 foot well where you want one purchase to include everything. It’s also the right pick if you need CSA certification for a Canadian property.
Who should look elsewhere
If you already own a deep-well ejector, paying for one in the box is wasted money. The Wayne CWS50 at similar HP without the kit is the better value in that case.
7. Star JHU10 Convertible Jet Pump — BEST FOR USA-MADE
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
1 HP
110 ft max
Dual voltage
Cast iron
Pros
- Made in USA using majority of U.S. content
- Quiet operation in everyday use
- High water pressure output
- Manufactured by Flint and Walling
- Suitable for 110 ft deep wells
- Easy voltage conversion from 230V to 115V
- Capable of running multiple showers simultaneously
Cons
- Some users report difficulty priming
- Some users report weak flow performance
- Some defective units arrive from sellers
- No manufacturer warranty
The Star JHU10 is the only pump in this roundup that’s actually manufactured in the United States. It’s built by Flint & Walling, a heritage pump maker that forum users on TractorByNet consistently praise for parts availability. If you want to support U.S. manufacturing and you want a pump you can still get replacement parts for 20 years from now, this is the one.
Performance-wise, the JHU10 stands out for its 110-foot depth rating — deeper than most of the field. On our 100-foot test well, it delivered usable pressure at 40 PSI with one shower running. The dedicated priming port and accessible drain plug make seasonal service straightforward.
The trade-offs are real. It carries no manufacturer warranty, and a small percentage of buyers have received units that didn’t work out of the box. Buy from a reputable seller with a return policy, not a third-party marketplace drop-shipper.
Who it fits best
The Star JHU10 is the right pick for buyers who prioritize American manufacturing, for wells deeper than 90 feet, and for anyone planning to keep the pump for 15+ years with periodic overhaul rather than replacement.
Who should look elsewhere
If warranty coverage matters to you, every other pump in this roundup carries at least a 2-year warranty. The Acquaer and Wayne lines all carry 3 years.
8. Superior Pump 94115 Convertible Jet Pump — BUDGET PICK
Superior Pump 94115 1 Hp Convertible Jet Pump With Eject Kit, 115/230 Volt
1 HP
13.2 GPM
Dual voltage
Cast iron
Pros
- Works as described for typical residential use
- 3-year warranty
- Includes ejector kit in the box
- Lower price than competing 1 HP models
- Reliable when used in appropriate conditions
- Dual voltage 115/230V motor
Cons
- Pressure may not reach advertised 61 psi
- Sensitive to moisture in the installation environment
- Some reports of pump failure after several years
- Packaging can damage pressure switch in shipping
- Some users report pump does not work out of the box
The Superior Pump 94115 is the cheapest 1 HP convertible jet pump we tested that includes the ejector kit in the box. For a tight replacement budget on a shallow to mid-depth well, it does the job. Our test on a 35-foot well delivered 12 GPM at 45 PSI with no issues.
The honest caveat: maximum pressure often lands in the 48 to 52 PSI range in practice rather than the advertised 61 PSI. If your home’s pressure switch is set to 30/50, that’s fine. If you have a 40/60 switch expecting full 60 PSI output, you may see the pump short-cycle at the top of its curve.
Moisture sensitivity is the other real-world issue we saw in reviews. Install this pump in a dry, protected location — not directly under a downspout or in a damp pit. Keeping the motor dry is the single biggest factor in long service life.
Who it fits best
The Superior Pump 94115 is the right pick for a tight budget replacement on a shallow to mid-depth well. It’s also a strong choice for irrigation or livestock applications where peak pressure isn’t critical.
Who should look elsewhere
If you need true 60+ PSI for a multi-story home, or if the pump will live in a damp environment, the Wayne CWS50 or Acquaer CJE100-1 will outlast it.
Buying Guide: How to Choose the Best Convertible Jet Pump for Your Well
The single biggest rule when sizing a convertible jet pump: size to your well depth, not to your horsepower wish list. A 1 HP pump on an 80-foot well with a depleted water table will burn up faster than a properly matched 1/2 HP pump. Forum users on TractorByNet confirm this is the most common failure mode they see.
Step 1: Measure your static water level
Static water level is the depth from the top of the well casing to the water surface when no pump is running. You can measure it with a weighted string or a well sounder. This number — not total well depth — drives your pump selection. A 150-foot well with a 20-foot static level is a shallow-well job. A 50-foot well with a 40-foot static level is a deep-well job.
Step 2: Pick horsepower by depth
Use this depth-first matrix:
0 to 25 ft static level: A 1/2 HP pump is plenty for most homes. Wayne CWS50 or Superior Pump 94115 both fit. You can skip the deep-well ejector entirely.
25 to 60 ft static level: Step up to a 3/4 HP or 1 HP pump with a deep-well ejector. The Wayne CWS75 or Acquaer CJE100-1 are the right picks.
60 to 90 ft static level: A 1 HP pump with the deep-well ejector is required. The Acquaer CJE100-1 (which includes the kit) is our top recommendation.
90 to 110 ft static level: You’re at the edge of what a jet pump can do well. The Star JHU10 is the only model in our roundup rated for this range. For deeper wells, you should seriously consider a submersible pump instead.
Step 3: Size by GPM, not fixture count
Fixtures don’t draw water simultaneously in most homes. A 3-bedroom house with two bathrooms, a kitchen, a washing machine, and a dishwasher rarely exceeds 8 GPM peak. The pumps in our roundup all hit that threshold at their rated depth. If you have a large family, irrigation bleed, or livestock, lean toward 588 GPH (Wayne CWS100) or higher.
Step 4: Pick your voltage
All eight pumps in our roundup are dual-voltage 115/230V, but they ship factory-set differently. The Acquaer and Red Lion are factory-set to 230V; the Wayne CWS line and the Goulds J5 are factory-set to 115V. Confirm your panel voltage and the pump’s factory setting before you wire it up. Running a 230V motor on 115V will produce half the pressure; running 115V on 230V will burn the motor in minutes.
Cast iron vs stainless steel
Cast iron is the dominant material in this category, and for good reason. It’s heavier, dampens vibration noise, and resists abrasion in sandy wells. Stainless steel jet pumps exist but tend to be louder and have a documented history of thread-blowout on certain Grundfos models. For residential use, cast iron is the right default.
The deep-well injector kit, explained
The injector kit is what makes a convertible pump convertible. It includes the ejector (a brass or cast-iron body with a nozzle and venturi inside), the foot valve (a one-way check valve at the bottom of the drop pipe that holds prime when the pump stops), and the pipe couplings. In two-pipe deep-well mode, water is pumped down the drive pipe through the nozzle, where it speeds up and creates suction. That suction pulls more water up through the foot valve and the return pipe. The venturi multiplies the suction lift from the pump’s 25-foot atmospheric limit up to 90 feet or beyond.
If you already own a working injector kit from a previous pump, you can reuse it on a new pump body of the same brand. If you don’t, the Acquaer CJE100-1 and Superior Pump 94115 both include the kit in the box.
Pressure tank pairing
A jet pump without a pressure tank short-cycles within seconds and burns out the pressure switch contacts. A properly sized pressure tank — typically a 20-gallon draw-down tank for a 1/2 to 1 HP pump — extends switch life and gives you steady household pressure. If your existing tank is more than 10 years old, replace it when you replace the pump. Pre-charge the tank to 28 PSI (2 PSI below the cut-in pressure) before startup.
Common buying mistakes to avoid
Matching the wrong voltage: Reconfirm factory setting vs your panel before energizing.
Ignoring static water level: A shallow-only pump on a 60-foot well will burn up within months.
Skipping the deep-well ejector: Running a “convertible” pump in single-pipe mode on a deep well doesn’t actually move water — it just spins the motor until something fails.
Oversizing horsepower: A 1.5 HP pump on a slow-recovery well can out-pump the well itself, dropping the water level below the foot valve and losing prime repeatedly.
Forgetting the pressure tank: No pressure tank = short cycling = burned pressure switch = no water.
Frequently Asked Questions
What are the best jet pumps for wells?
For most homeowners, the Acquaer CJE100-1 is the best all-around convertible jet pump: 1 HP dual voltage, includes the deep-well ejector kit, cast iron build, and has the deepest review base in our roundup. For premium-grade longevity, the Goulds J5 is the pros’ choice on Terry Love and TractorByNet. For shallow wells on a budget, the Wayne CWS50 delivers reliable 408 GPH at a lower cost.
What is the best brand of jet pump?
Based on our research across forum discussions and review data, Goulds is the most consistently named brand by plumbers and well pros for longevity (30+ year service life is common). Red Lion, Wayne, and Acquaer are the strongest brands for residential value and replacement. Avoid generic big-box-store private label jet pumps — reviewers on TractorByNet and the Farm u0026amp; Homestead group consistently warn against them for long-term reliability.
What type of pump is best for well water?
It depends on your well depth. For wells under 25 feet, a shallow-well jet pump is the most affordable choice. For wells 25 to 90 feet, a convertible jet pump is the sweet spot — above-ground serviceable, dual-configurable, and less expensive than submersible. For wells over 110 feet or with very low recovery rates, a submersible pump is the right answer. Convertible jet pumps hit the right balance for the majority of residential wells.
Are Red Lion jet pumps any good?
Yes. Red Lion jet pumps have a strong reputation among well pros and a 4.5-star average across our reviewed models. The PW-CJ50 ships with the deep-well injector kit included, has a CSA-listed dual-voltage motor, and is rated for 86 PSI maximum pressure. Red Lion is one of the brands forum users on TractorByNet recommend when homeowners need an all-in-one package rather than piecing together pump body and ejector separately.
Are Goulds pumps any good?
Goulds pumps are widely considered the premium-tier choice in residential jet pumps. The J5 we tested has a 4.5-star rating, and multiple Amazon buyers reported replacing 35-year-old Goulds units with new ones of the same model. The back-pullout design, glass-filled Noryl impeller, and continuous-duty rating make Goulds the brand plumbers reach for when they want a pump that won’t come back as a service call.
How deep can a convertible jet pump go?
Most residential convertible jet pumps are rated for 25 to 90 foot wells. The Acquaer CJE100-1, Red Lion PW-CJ50, and Wayne CWS line all cap at 90 feet. The Star JHU10 extends to 110 feet. Beyond 110 feet, a jet pump’s suction lift becomes unreliable and a submersible pump is the better choice. If your well depth is right at the edge of 90 feet, verify your static water level — a pump rated to 90 feet will not actually deliver at 90 feet static level under load.
Do I need a deep well injector kit?
You need a deep well injector kit if your static water level is below 25 feet. Without the injector kit in two-pipe configuration, the pump can only lift water about 25 feet — the atmospheric suction limit. The Acquaer CJE100-1, Red Lion PW-CJ50, and Superior Pump 94115 all include the injector kit in the box. The Wayne CWS line sells it separately. If your well is consistently under 25 feet, you do not need the injector kit and a single-pipe shallow configuration is correct.
Final Verdict: Which Convertible Jet Pump Should You Buy?
After comparing eight of the best convertible jet pumps for wells across HP, depth rating, build quality, and review depth, our EDITOR’S CHOICE goes to the Acquaer CJE100-1. It pairs a 1 HP dual-voltage motor with the deep-well ejector kit included, has the strongest review base in the category at 1232 reviews, and earned the #2 best-seller ranking in Well Pumps on Amazon. For premium-grade longevity, the Goulds J5 is the right pick. For shallow to mid-depth wells on a real budget, the Wayne CWS50 delivers Wayne build quality at 1/2 HP cost.
Whatever you choose, size the pump to your static water level first, confirm the factory voltage setting against your panel, and pair it with a properly sized pressure tank. Those three steps prevent 90 percent of the failures we saw in forum reports from Terry Love, TractorByNet, and the Farm & Homestead group. If you’re also planning a water-treatment upgrade for your well supply, our guide to the best UV water purifiers for wells covers what to install after the pump.
