Well Pump Replacement Cost: Ranges and Price Drivers

Published cost guides put a typical well pump replacement at roughly $900 to $2,500, according to This Old House’s 2026 guide. Submersible pumps cost the most, at about $1,000 to $2,500 in the HomeGuide figures that American Home Shield cites, against $400 to $1,400 for a shallow-well jet pump. Where your bill lands depends mostly on how deep the pump hangs and how much comes out of the well with it: wire, drop pipe, check valve, control box, pressure switch and sometimes the tank.

What published cost guides say

Two cautions. These are national figures; neither source breaks them out by region. And the low end of the American Home Shield survey ($70) reflects small repairs, not a pump swap. Get two local quotes and use this table to judge whether they are in a normal range.

What drives the price

Pump type

Jet pumps sit above ground, so swapping one is a plumbing job at the wellhead or in the basement. Submersibles hang inside the well. This Old House notes they cost more to install for exactly that reason: the installer has to pull the old one out and lower the new one in. Constant-pressure systems add a variable-speed drive, which is why they top the table. The well pumps guide explains which type a given well needs; our roundups of submersible pumps and shallow well pumps compare models by rated flow and head.

Well depth and pump setting

Depth is the biggest multiplier for submersibles. A deeper setting means more pipe and wire to pull and reinstall, more time, and at some depth a pump-hoist truck instead of hand pulling. This Old House lists well depth, horsepower, installation complexity, and labor and accessibility as the factors that raise the price, and says the lifting equipment needed is part of the labor cost. It adds that higher-horsepower motors, for larger homes or higher water demand, raise both equipment and installation cost.

Wire, drop pipe and check valves

Once the pump is out of the well, the installer will inspect everything that came up with it. American Home Shield notes that the drop pipe, wiring or pressure tank may also need replacing, which raises the total. Franklin’s AIM manual explains why these parts matter:

• Check valves. Franklin requires at least one positive-sealing check valve, within 25 ft of the pump if the pump has none built in, and says never to use swing-type valves with submersibles. A leaking or wrong check valve causes water hammer and upthrust that can damage a new pump, so expect it to be replaced on the way back down.
• Wire. Franklin’s manual publishes cable-size tables by motor horsepower, voltage and cable length, so a deeper setting or a bigger motor can mean new, heavier cable. Its preliminary tests (insulation and winding resistance) are also how a damaged cable is found.
• Drop pipe. Franklin lists split pipes and broken joints among the results of water hammer from a missing or failed check valve; damaged pipe is replaced rather than reinstalled.

Control box and pressure switch

A 3-wire submersible needs a control box at the surface. Franklin says the box and motor are two pieces of one assembly whose horsepower and voltage must match, and its warranty applies only with a Franklin box on a Franklin motor. A new motor of a different size or brand therefore means a new box. The pressure switch is the other surface part to ask about: Franklin’s troubleshooting table lists a damaged switch, with poor contact points, as a cause of a motor that won’t start, and the fix is to clean the points or replace the switch.

Pressure tank

If the old pump died from short cycling, the tank is often why. A waterlogged or undersized tank will wear out a new pump the same way. Neither cost source prices the tank separately, so ask for it as its own line item. See well pressure tank replacement for how to tell whether yours has failed.

Make sure the pump is really dead first

A pump pull is the expensive part of the job, so it pays to rule out cheaper faults first. Franklin’s AIM manual lists preliminary tests to run before removing a motor from the well: line-to-line voltage (within ±10% of nameplate), amperage on all motor leads, insulation resistance to ground, and winding resistance. A good installer runs these at the surface. The same manual’s troubleshooting table also lists causes that are fixed without pulling anything: blown fuses or tripped breakers, a damaged pressure switch, a control box malfunction, and a water level that has dropped below what the pump needs. Our well pump not working guide covers that sequence.

Questions to ask a pump contractor

• What did the voltage, amp and resistance tests show, and which part failed?
• How deep is the pump set, and do you pull by hand or with a hoist?
• What is the replacement pump’s rated flow at our total dynamic head?
• Is the quote including new wire, drop pipe, check valve(s), control box and pressure switch, or only if needed?
• Will you check the pressure tank precharge and the tank’s condition?
• What warranty covers the pump, the motor and the labor?

A quote that itemizes the pump, the labor to pull and reset, and each “while it’s out” part is easier to compare than a single number, and it shows you which of the drivers above is behind the price.
