Well pump replacement

A well pump replacement in the Prescott area typically runs $1,500 to $2,827 on national average, with depth adding roughly $500 to $1,000 per 100 feet. Because local wells commonly run 280 to 400 feet, most replacements here sit at the higher end of that range rather than the average. Depth, horsepower, and the condition of the drop pipe drive nearly all of the cost.

What the price actually depends on

Factor	Effect
Depth to the pump	The largest driver. More pipe, more wire, more time
Horsepower needed	Set by depth, lift, and how much water the house needs
Drop pipe condition	Old galvanized pipe often cannot be reused
Wire condition	Drop wire is usually replaced with the pump
Wellhead condition	A failed pitless adapter means excavation
Pressure tank	Frequently replaced at the same time
Access	Whether a truck can reach the wellhead

National aggregator figures for 2026 put a submersible in a 200 foot well at roughly $1,800 to $3,000, and a 400 foot well at $4,000 to $6,000 or more. Depth-related cost alone runs about $3 to $8 per foot in combined material and labor.

Local depth context, from vendor-published averages rather than a survey:

Area	Typical well depth
Chino Valley	around 280 ft
Prescott Valley	around 300 ft
Prescott	around 320 ft
Big Chino area including Paulden	280 to 400 ft

Your own well is whatever it is. If you have the original drilling record, it answers this exactly.

Why the water table matters when you size a new pump

In most of the country you pull the old pump and put back something similar. Around Prescott that assumption is worth checking.

Groundwater levels in the Chino Valley area have been falling for decades. For a well drilled 50 years ago, depth to water has typically increased 80 to 100 feet, and parts of Williamson Valley have seen reported declines as high as 8 feet a year. See falling groundwater and what it means for your well for where those figures come from.

That has three practical consequences at replacement time:

The pump may need to go deeper. If the standing water level is now below where the old pump sat, setting the new one at the old depth means it runs dry.

Deeper can mean more horsepower. Lifting water further takes more work. A pump sized for the 1990s water level may be undersized for today’s.

There may be less room than you think. A pump has to sit above the bottom of the well to avoid drawing sediment. If the water level has dropped a long way, the workable space between water level and well bottom narrows.

A contractor who measures the current static water level before quoting is doing the job properly. One who does not is guessing. See falling groundwater and what it means for your well.

What replacement involves

Confirm the pump is the problem. Above-ground faults are cheaper and more common. See well pump repair.

Measure the well. Static water level, total depth, and current pump setting.

Size the replacement. Depth and lift, plus household demand. A house with several bathrooms and irrigation needs more than a cabin.

Pull the old assembly. Pump, drop pipe, wire, and safety rope come up together on a reel.

Inspect what comes out. The condition of the old pump and pipe frequently explains the failure, and sometimes reveals a well problem rather than an equipment problem.

Install and set depth. New pump, new wire, usually new pipe.

Test. Flow rate, pressure, amp draw, and recovery.

Ask to see the old pump. It is your equipment, and its condition is the evidence behind whatever the contractor tells you happened.

When it is the well and not the pump

Sometimes the pump is fine and the well has changed. Signs that point that direction include a pump that runs but delivers air, a well that recovers slowly after heavy use, and increasing sand or sediment. The fixes there are different and more involved, including lowering the pump, deepening the well, or hydrofracturing. A pump contractor should tell you plainly if that is what they are seeing rather than selling you a pump that will not fix it.
