Short answer

Four national cost guides put a typical well pump replacement at $900 to $2,821, with averages of $1,750 to $1,897. Submersible pumps run $1,000–$2,500 installed; shallow-well jet pumps $400–$1,000. Before paying for a new pump, rule out a $26–$139 pressure switch, capacitor or control box.

What we did: We set four national cost guides side by side, priced the same 1/2 HP pump at five retailers on one day, and listed the cheap parts to rule out before replacing a pump.

⚠️ Safety first. A well pump runs on 115 V or 230 V. Turn off the pump breaker and confirm the circuit is dead with a tester before touching the pressure switch or control box. Franklin Electric’s control box checks need live voltage (“Power must be on for these tests”): a job for a licensed electrician or pump installer. Red Lion warns capacitors can hold a charge after disconnection. A submersible can weigh over 100 pounds and hangs on pipe and wire in the casing (This Old House, March 2026).

$1,000–$2,500 is normal for a 1/2–1 HP pump by every source; over $2,821, ask why. Compare the “typical range” column only (type rows mix installed and pump-only prices).

Labor is a quarter to half of the bill. A job takes 3–6 hours (HomeGuide).

Ask about what pushes a quote up: pump depth; a change of pump type; whether the puller truck is included; new drop pipe and wire (how many feet, what price?); after-hours rates (usually double, $50/hr vs $100/hr, HomeAdvisor repair page); and whether a new tank’s old air charge was tested first.

Check cheap parts first

Symptom Check first Part price (2026-10-05) If that’s fine
No water at all Breaker or fuse; pressure switch not closing Pressure switch $25.95 Control box, wiring, then pump
Pump won’t start, 3-wire system Control box and start capacitor Capacitor $76.00; control box $138.40 Motor or cable tests before pulling
Pump turns on and off every few seconds Tank air charge: 2 psi below cut-in, e.g. 28 psi on a 30/50 switch (Red Lion) $0 (tire gauge) Pressure switch, check valve, leaks
Pump runs and won’t shut off Pressure switch contacts and setting $25.95 Leak in drop pipe, low well level, worn pump
Low pressure, jet pump Prime, suction leaks, clogged foot valve No price found yet Worn impeller, well drawdown

A 2-wire pump has no control box (its start switch is in the motor).

Ask for these tests before the pump is pulled

Franklin lists tests to “complete before removing the motor from the well”. Ask the installer for the readings:

  1. Line voltage: within ±10% of the motor nameplate.
  2. Amps on each motor lead, against the motor spec table.
  3. Insulation resistance, each lead to ground, 500 V megohmmeter, breaker open:
Reading (motor plus cable, in the well) Franklin’s meaning
2.0 megohms or more New motor
0.5–2.0 megohms Motor in good condition
Less than 0.5 megohms Insulation damage: locate and repair
  1. Winding resistance, line to line. Low: shorted winding. High: open winding, open cable or bad splice.

A low reading can be the cable; a bad capacitor shows as odd amps. Neither needs a new pump. Franklin: a capacitor “may test good” on an ohmmeter and still be weak.

Warranty covers the pump, not the labor

Even a free pump means paying for pulling and reinstalling. Keep the receipt.

DIY or hire a pro

Job DIY?
Reset breaker, read pressure gauge, check tank air (power off, drain, tire gauge on the air valve) Yes
Replace a pressure switch Experienced DIYer only, power off and verified dead
Replace a control box capacitor Usually pro: tests need power on; capacitors hold a charge
Swap an above-ground jet pump like-for-like Plumbing yes; wiring by a qualified technician per the NEC (Goulds). Re-prime after.
Pull and replace a submersible Pro: hundreds of feet of pipe and wire, over 100 lb. HomeAdvisor and This Old House say not DIY.
Change pump size or type Pro. Check the numbers with the well pump size calculator.

Repair or replace? Pumps last 10–15 years (HomeGuide), 8–15 (HomeGuide repair page), about 15 (HomeAdvisor repair page). HomeGuide: replace a 10–15-year-old pump that keeps needing repairs; repair if the fix is under 50% of a new one. Rapid cycling shortens life; Franklin’s limit is 300 starts per 24 hours for single-phase motors up to 3/4 HP, 100 for 1 HP and up.

FAQ

How much does it cost to replace a well pump? Four national guides say $900 to $2,821, averaging $1,750 to $1,897. Most jobs land at $1,000–$2,500. Constant-pressure systems cost $2,000–$5,000.

Can I replace a well pump myself? An above-ground jet pump, yes, if a qualified person wires it and you re-prime it. A submersible is pulled up the well, often with a truck. Hire a pro.

Is it the pump or the pressure switch? Check the switch first. A bad switch can stop the pump starting or stopping, and a new one is about $26.

Method: we set the four cost guides side by side, each with its own date, and kept their figures separate instead of averaging them. We priced the same class of pump and the common small parts at retailers on 2026-10-05, and pulled the pre-pull tests, start limits and warranty terms from the manufacturer manuals into checklists and tables. Page references are in the sources above. We have not collected contractor quotes or replaced a pump ourselves.
