What Does It Cost to Replace a Well Pump?

The honest answer: nobody can price a well pump replacement without seeing the well. We quote every job after we diagnose it, because two houses on the same road can need very different work. What we can tell you is which type of system you are dealing with, and what makes one job cost more than another.

• Submersible pump replacement — the most common job in North Texas, and the one most affected by well depth.
• Jet pump replacement (shallow well) — the simplest replacement, since the pump sits above ground.
• Jet pump replacement (deep well, two-line) — more plumbing and more setup than a shallow-well jet pump.
• Constant pressure / variable speed system — the most involved option, and the one that eliminates pressure fluctuations entirely.

What's Actually Included in the Job?

A typical submersible pump replacement involves pulling the old pump, installing a new pump and motor, replacing the drop pipe and wiring, and lowering everything back down. Here is what goes into the quote:

• Pump and motor — the largest single line, driven by horsepower and brand.
• Drop pipe — scales directly with how deep the pump sits.
• Wiring and connectors — a small share of the total, but never worth reusing if corroded.
• Labor — the second-largest line, and again driven by well depth.
• Miscellaneous hardware — pitless adapter, torque arrestor, check valve.

The deeper your well, the more labor and materials required. A 150-foot well is straightforward. A 400-foot well costs significantly more.

Key Factors That Drive the Price Up or Down

Well Depth

This is the single biggest cost factor. Every additional foot means more drop pipe, more wire, and more labor. Wells in the Fort Worth–Dallas area typically range from 100 to 500+ feet. A 400-foot well costs meaningfully more than a 150-foot well for the same pump.

Pump Size (Horsepower)

Most residential wells use ½ HP to 1½ HP pumps. A ½ HP submersible is the entry point. A 1½ HP pump costs more. Going bigger costs more but ensures adequate pressure.

Access and Site Conditions

Tight spaces, low ceilings, buried well caps — these all add labor time and cost.

Condition of Existing Components

Corroded wiring, cracked pitless adapters, or deteriorated well casings need to be addressed during replacement. Unexpected repairs add to the total.

Pressure Tank Condition

Your pressure tank works hand-in-hand with the pump. If it's waterlogged, replacing it during the pump job is smart — and cheaper than a separate call. Tanks are a routine install.

Signs You Need Replacement vs. Repair

Likely Needs Replacement

• Pump is 15+ years old and failing
• Motor has burned out
• Repeatedly cycling despite tank and switch being fine
• Significant drop in flow rate that servicing hasn't fixed
• Pump is producing sand or sediment

Might Only Need Repair

• No water, but pump is under 10 years old — could be wiring, switch, or capacitor
• Breaker keeps tripping — may be a wiring problem
• Low pressure — could be a pressure tank issue

A proper diagnosis saves you from paying for a replacement you don't need. At Legacy Water Well, we troubleshoot first.

Texas-Specific Considerations

• Depth matters more here. Many wells tap the Trinity Aquifer at 200-500+ feet.
• Heat kills pumps faster. Texas summers put extreme stress on motors.
• Licensed well drillers required. Texas requires licensed installers for well work.
• No state price regulation. Get at least two itemized quotes.
