Our picks

1. Best overall shallow well pump

   Red Lion RJS-100-PREM 1 HP Cast Iron Shallow Well Jet Pump

   A cast iron 1 HP jet pump with enough flow for a full house and a hose. Cast iron is heavier and stiffer than a plastic housing, which is why many owners prefer it for a pump that runs every day. Skip it if your water is acidic (pH under about 6.5) and you won't treat it, since cast iron can rust from the inside.

   • 1 HP, 115/230 V
   • Up to 23 GPM (at 5 ft)
   • Max suction lift 25 ft
   • Cast iron body, glass-filled thermoplastic impeller
   • 30/50 pressure switch installed

2. Best value cast iron pump

   Wayne SWS100 1 HP Cast Iron Shallow Well Jet Pump

   A cast iron 1 HP shallow well pump that usually costs less than the Red Lion. Wayne rates it at 630 gallons per hour (about 10.5 GPM) at 50 psi, which is honest for a real-world setting. Skip it if you need more than one shower and a hose running at once.

   • 1 HP, 120/240 V
   • 630 gallons per hour at 50 psi
   • Max suction lift 25 ft
   • Cast iron, 1-1/4" suction, 1" discharge
   • 30/50 pressure switch; 3-year limited warranty

3. Best if your water is near 25 ft (convertible)

   Red Lion RJC-100 1 HP Convertible Jet Pump

   A convertible pump runs as a shallow well pump or, with the included ejector down the well, pulls from up to 90 feet. Pick it when your water level is close to the 25-foot limit. Skip it if your water sits well above 25 feet; a shallow-only pump gives more flow for the money.

   • 1 HP, 115/230 V
   • Up to 20 GPM
   • Shallow setup under 25 ft; deep setup 25–90 ft
   • Deep well ejector included
   • Cast iron body, 30/50 switch

4. Best pro-grade pump

   Goulds J5S 1/2 HP Shallow Well Jet Pump

   A contractor-grade pump sold mainly through plumbing supply houses. Goulds publishes flow at every lift and pressure, so you know what you'll get. The back pull-out design lets a tech service the motor without cutting pipe. Skip it if you're buying on price: at last check it cost nearly twice the Red Lion RJS-100 at the same store, with half the horsepower.

   • 1/2 HP, 115/230 V
   • 10.2 GPM at 5 ft lift, 40 psi
   • 6.2 GPM at 25 ft lift, 40 psi
   • Cast iron, stainless wear ring
   • Back pull-out design; 30/50 switch

5. Best for cabins and corrosive water

   Flotec FP4012-10 1/2 HP Thermoplastic Shallow Well Jet Pump

   A plastic-body pump that won't rust, which suits acidic or salty water and seasonal cabins. Flow is modest. Skip it for a family home with two bathrooms: 8 GPM at best leaves little room for two showers at once.

   • 1/2 HP, 115/230 V
   • 8 GPM max; 6.4 GPM at 10 ft lift
   • Max suction lift 25 ft; max 77 psi
   • Thermoplastic body
   • 30/50 switch; 1-year limited warranty

6. Best same-day pickup

   Everbilt 1/2 HP Shallow Well Jet Pump (J100A3)

   A store-brand plastic jet pump you can usually pick up the same day. That matters when the old pump died this morning. Skip it if you have time to order: the Flotec costs about the same with better published specs.

   • 1/2 HP
   • 432 gallons per hour at 40 psi
   • Max suction lift 25 ft
   • Thermoplastic housing, self-priming

Quick comparison

Makers rate flow at different lifts and pressures, so these numbers don't line up perfectly. A "max GPM" figure is measured at low lift and low pressure. The flow at 40 to 50 psi is closer to what your shower sees.

Shallow, deep or convertible: the 25-foot rule

A shallow well jet pump sits above ground and pulls water up the suction pipe. Air pressure pushes the water up as the pump lowers pressure in the pipe. That only works to about 25 feet in practice, and every pump in this guide is rated for 25 feet of lift at most.

The number that matters is the pumping water level: the distance from the pump down to the water while the pump is running. That's not the well's total depth. Water levels drop while you pump and often drop in late summer. A well that measures 18 feet to water in April can be 26 feet in August.

A convertible pump comes with an ejector that goes down the well on a second pipe. Set up as a shallow pump, it works like the others. If the water level drops later, you add the ejector instead of buying a new pump.

How to choose a shallow well pump

1. Size the flow, not the horsepower

Count what runs at the same time: showers, a washer, a hose. Then compare pumps on flow at 40 to 50 psi and at your lift. Goulds' published data for the 1/2 HP J5S shows how much lift matters:

At 25 feet and 50 psi, a 1/2 HP pump barely moves water. Goulds' 1 HP J10S still makes 10.4 GPM at that same point. If your water is deep in the shallow range, or you want 40/60 pressure, step up to 1 HP.

2. Cast iron or thermoplastic

• Cast iron (Red Lion RJS, Wayne SWS100, Goulds J5S): heavier and stiffer. It's the traditional choice for a pump that runs every day. It can rust inside if your water is acidic, so check your pH first.
• Thermoplastic (Flotec FP4012, Everbilt J100A3): won't rust, lighter, and usually cheaper. A plastic housing is less forgiving of freezing or over-tightened fittings. Flotec backs the FP4012-10 for 1 year. Wayne lists 3 years on the SWS100, and Red Lion lists 3 years on its RJS-50-PREM.

3. Check the pipe sizes

Most shallow well jet pumps here use a 1-1/4 inch suction and a 1 inch discharge. Don't neck the suction pipe down to a smaller size. A restricted suction line cuts flow and can make the pump lose prime.

4. Plan for what's in the water

Shallow wells, sand points and dug wells pick up more surface water than deep drilled wells. That means more sediment and a higher risk of coliform bacteria. Put a foot valve with a screen on the suction line, and a sediment filter after the tank. Test the water once a year (here's what to test).

Mistakes to avoid

• Measuring the well instead of the water. Measure to the water while pumping, in the dry season.
• Buying max GPM. Compare flow at 40 to 50 psi and your lift.
• Skipping the foot valve or check valve. Without one, the pump loses prime every time it stops.
• Running the pump dry to prime it. Fill the pump case with water through the priming plug before the first start. Running dry can wreck the seal in seconds.
• Leaving it unprotected in winter. A pump in an unheated well house needs heat or draining.
• Ignoring the pressure tank. A jet pump with no working tank short-cycles. Set the tank's air charge 2 psi below the switch's cut-in.

Once the pump is running, a whole-house filter matched to your test handles iron, smell and sediment.
