Our picks

1. 

   Best overall for most drilled wells

   Franklin Electric FS Series 4" Submersible Well Pump (10 GPM)

   The same pump line well drillers install. Floating-stage hydraulics are built to resist wear from sand, and the motor is rated for continuous duty. Skip it if you want to buy online and pay little: it costs more than house brands, and Franklin's warranty is short, so the installer's workmanship matters as much as the pump.

   • 10 GPM models from 1/2 HP; 1 HP 2-wire (10FS1P4-2W230) has 13 stages
   • 1 HP model: 526 ft shut-off head
   • AISI 304 stainless body, acetal impellers
   • Check valve included; NSF/ANSI 61
   • 230V; 2-wire and 3-wire versions
   • Warranty: 12 months from install / 24 months from manufacture

2. Best constant-pressure pump (soft start)

   Grundfos SQE Constant-Pressure Submersible Pump (e.g. 10 SQE05-160)

   The motor speeds up and slows down to hold one pressure instead of swinging between 40 and 60 psi. Soft start means low starting current, which also helps on a generator. Skip it if your budget is tight or your installer doesn't know the system: it costs much more than a fixed-speed pump, and the electronics are a dealer repair, not a hardware-store one.

   • 10 SQE05-160: 1/2 HP, 10 GPM, 200–240V
   • 2-wire with ground
   • Up to 450 ft of head (at 5 GPM)
   • Pressure set 40–100 psi
   • Soft start, dry-run and overload protection
   • Needs the CU 301 control unit and a pressure sensor

3. Best for sandy wells

   Goulds GS Series 4" Submersible Pump (10GS05422C)

   A floating-stack pump with a bearing Goulds designed to tolerate sand and abrasives, which are what wear out most pumps early. Skip it if your well is clean and shallow: you'd be paying for sand protection you don't need, and you still want a spin-down filter if sand reaches the house.

   • 10GS05422C: 1/2 HP, 10 GPM, 230V, 2-wire
   • CentriPro motor
   • GS line covers 1/2 to 5 HP
   • Stainless steel construction and check valve
   • "Guardian" polymer bearing for sand and over-pumping
   • Assembled and tested in the USA (per Goulds)

4. Best value 2-wire pump

   Red Lion RL12G05-2W2V 1/2 HP Submersible Well Pump

   Red Lion is a Franklin Electric brand aimed at DIY buyers. This is a simple 2-wire pump that suits wells where the water level sits well under 100 feet. Skip it if your pumping level is deep: 1/2 HP runs out of flow quickly as head climbs, and the plastic discharge is less robust than an all-steel pump.

   • 1/2 HP, 12 GPM (at 5 ft of head), 230V
   • 2-wire: no control box
   • Max head 212 ft (supplier listing)
   • Stainless shell; thermoplastic discharge and motor bracket
   • Built-in suction screen and check valve

5. Best for deeper wells (3-wire, 1 HP)

   Red Lion RL12G10-3W2V 1 HP 3-Wire Pump with Control Box

   The start capacitor and relay live in a box in your basement, so a common failure is a cheap swap instead of pulling the pump. Skip it if you're replacing a 2-wire pump and don't want to run a third conductor: a 3-wire motor needs 3 wires plus ground down the well.

   • 1 HP, 12 GPM (at 5 ft of head), 230V
   • 3-wire, control box included
   • Max head 434 ft; max depth 250 ft (supplier listing)
   • Stainless shell; thermoplastic discharge
   • Built-in suction screen and check valve

6. Best budget pump off the shelf

   Everbilt 1/2 HP 2-Wire Submersible Deep Well Pump (EFSUB5-122HD)

   A house-brand pump sold off the shelf, which matters when your water is out on a weekend. Skip it if your water level is deeper than about 100 feet or you want a long track record: the published specs are thin and there's less dealer support than for Franklin, Goulds or Grundfos.

   • 1/2 HP, 10 GPM, 230V
   • 2 power wires plus ground
   • Home Depot lists 60–100 ft wells
   • Stainless steel construction

Quick comparison

GPM figures are the pump's nominal rating. Real flow drops as head rises, so always check the maker's pump curve at your own total head.

How to choose a submersible well pump

1. Start with flow (GPM)

Installers use two quick methods. The fixture count method treats each fixture as 1 GPM: a two-bath home with a kitchen, washer and softener adds up to about 10 fixtures, so about 10 GPM. The peak-demand method adds up what runs at once. Two showers, a washer and a sink running together can use 12 to 20 GPM, depending on fixture age. Most homes land on a 10 or 12 GPM pump.

Two limits matter more than your wish list:

• Well yield. The rule installers repeat: never install a pump with more capacity than the well. Your well log or the driller's yield test tells you what it can deliver.
• Treatment equipment. Backwashing iron filters and softeners need a minimum flow to clean themselves. Check the backwash rate of your whole-house filter or filter and softener combo before you downsize a pump.

2. Work out total dynamic head

Horsepower only means something against head: the total height and pressure the pump must push against. Add up:

1. Pumping level: the depth of the water while the pump runs (static level plus drawdown), not the depth of the hole.
2. Rise to the house: any elevation from the wellhead to the pressure tank.
3. Pressure: 1 psi equals 2.31 feet of head. A 60 psi cut-out adds about 139 feet.
4. Friction: pipe and fittings. It grows with flow and with smaller pipe; long runs at 10+ GPM often justify 1-1/4" pipe.

Example: water at 120 ft while pumping, 10 ft of rise, 60 psi (139 ft) and 15 ft of friction gives about 284 ft of total head. A 1/2 HP 10 GPM pump may still move water there, but at a much lower GPM. That's when a 3/4 or 1 HP model of the same series makes sense.

*Assumes 10 ft of rise, 139 ft for 60 psi and 15 ft of friction; use your own numbers. Find your total head on the maker's pump curve and read the GPM. If the 1/2 HP curve gives less flow than you need, step up to the 3/4 or 1 HP model in the same series.

3. 2-wire or 3-wire

A 2-wire motor has its start parts sealed inside the motor down the well. There's no box to buy, and nothing above ground to corrode. If a start part fails, though, the whole pump comes out. 2-wire motors top out around 1-1/2 HP.

A 3-wire motor keeps the start capacitor, relay and overload in a control box above ground. Those parts can be swapped in under an hour without pulling the pump. They are also more exposed to heat and moisture. Many installers pick 3-wire for deep wells, where pulling a pump costs the most.

If you're replacing a pump, match what's in the well unless you're also replacing the drop cable. A 3-wire motor needs three conductors plus ground.

4. Voltage

Most residential submersibles are 230V, and 230V draws half the current of a 115V motor for the same power. A 115V pump only makes sense on a short, shallow run where 115V is what you already have.

5. Fixed speed or constant pressure

A standard pump runs flat out between the pressure switch's cut-in and cut-out, often 40 and 60 psi. A constant-pressure pump such as the Grundfos SQE changes speed to hold one setting. You notice it in the shower. It also starts softly, which helps generators and backup power. The trade-offs are price and electronics that a pump dealer, not you, will service.

6. Build quality

Look for a stainless pump body, a built-in check valve, NSF/ANSI 61 listing for drinking water, and sand tolerance if your well makes sand. Brands well drillers install every day, like Franklin, Goulds, Grundfos and Red Lion, are also the ones local suppliers stock parts for.

Mistakes to avoid

• Buying horsepower instead of head. An oversized pump can draw the well down and run dry. An undersized one runs constantly at low flow.
• Using well depth instead of pumping level. A 300-foot well with water at 60 feet needs a very different pump than one with water at 250 feet.
• Ignoring the pressure tank. A small or waterlogged tank makes any pump short-cycle and fail early. Aim for at least one minute of run time per cycle.
• Skipping sand control. Sand wears impellers quickly. If you see grit in fixtures, read our sediment guide and choose a sand-tolerant pump.
• Forgetting to disinfect. Any time the pump is pulled, the well is opened to bacteria. Shock-chlorinate afterward and test for coliform before drinking.
• Not budgeting for install. Pulling and setting a deep pump usually takes a pump hoist or truck. Equipment is only part of the cost; see our water system cost guide for how treatment adds up.

DIY or hire a pro?

Swapping a pump hung shallow on poly pipe is something handy owners do with a helper. Deeper pumps on steel or heavy PVC, 3-wire conversions and anything involving the well cap seal or pitless adapter are jobs for a licensed pump installer. A dropped pump can cost far more than the labor you saved.

Not sure whether your water is hard on equipment? A broad lab test shows sand-related turbidity, iron and low pH, which all shorten pump and tank life.
