Dropped Pump in Well: Recovery Options & Costs

A dropped pump is one of the worst well problems — your water source is blocked by your own equipment sitting at the bottom. The good news: recovery is often possible. The bad news: it's not guaranteed, and costs can add up quickly. Here's what to expect.

How Pumps End Up at the Bottom

Most Common: Pipe Failure

The drop pipe connecting your pump to the surface corrodes over time. When it fails, the pump plummets to the bottom. This typically happens:

• At the top of the drop pipe — Where air and water meet, corrosion is worst
• At couplings — Threaded connections are stress points
• In aggressive water — Low pH, high minerals accelerate corrosion

Galvanized steel pipe is most vulnerable. PVC and stainless steel last longer.

No Safety Rope

A safety rope (or cable) connects the pump to the wellhead independently of the drop pipe. If properly installed, a failed pipe doesn't mean a lost pump — the rope catches it. Unfortunately, many older installations lack safety ropes, or the rope was never replaced when it deteriorated.

Installation or Service Error

Pumps sometimes drop during service:

• Pipe breaks during pulling
• Equipment failure on the pulling rig
• Improper handling or rushing

This is why professional pump service matters — proper equipment and technique minimize risk.

Wire Pull-Out

In rare cases, the electrical wire can pull out of the pump motor, leaving the pump with no connection at all. This usually happens with improper splice connections.

Step 1: Video Inspection

Before any recovery attempt, we need to see what we're dealing with. A downhole video camera reveals:

• Pump position — Is it sitting flat or wedged at an angle?
• Obstruction — Is pipe, wire, or debris tangled around it?
• Well condition — Any casing damage, offsets, or restrictions?
• Attachment points — Can we hook onto the pump or pipe?

Cost: $200-400 for video inspection

This is money well spent — attempting blind recovery wastes time and can make things worse.

Recovery Methods

Fishing Tools

"Fishing" is the industry term for retrieving objects from wells. Specialized tools include:

Overshots

Cylindrical tools that slide over the pipe or pump and grip from the outside. Work best when the pump is sitting upright with accessible pipe above it.

Spears

Tools that go inside the pipe and expand to grip from within. Useful when the top of the drop pipe is accessible.

Grapples

Hook or claw-type tools that grab onto whatever they can reach. Used when the pump is at an angle or conventional tools won't work.

Magnets

Strong magnets can sometimes lift smaller components or wire. Limited effectiveness on larger pumps.

The Recovery Process

1. Video inspection to assess situation
2. Select appropriate fishing tool
3. Lower tool to pump depth
4. Attempt to engage pump or pipe
5. Apply steady upward pressure
6. If successful, slowly retrieve pump
7. If unsuccessful, try different tool or approach

Success Factors

Favorable conditions:

• Pump sitting upright at bottom
• Sufficient casing diameter for tools
• No debris or tangled wire
• Straight casing with no offsets

Difficult conditions:

• Pump wedged at an angle
• Wire wrapped around everything
• Pump stuck in casing restriction
• Multiple pieces (pipe and pump separated)

Recovery Costs

Note: Failed recovery attempts still cost money. Multiple attempts can exceed the cost of alternatives.

When Recovery Fails

Option 1: Install Pump Above the Dropped One

If the dropped pump is sitting low enough, you can sometimes install a new pump above it:

• Requires sufficient depth between pump and water level
• New pump set shallower than original
• May reduce available drawdown
• Old pump remains in well permanently

This only works if your well has adequate depth and water level.

Option 2: Drill a New Well

Sometimes drilling a new well is more economical than continued recovery attempts:

• Old well may have other issues (poor yield, bad water quality)
• Multiple recovery attempts getting expensive
• New well can be located for better access
• Modern drilling may find better aquifer

New well cost: $15,000-35,000+ depending on depth and geology.

Option 3: Well Rehabilitation

In some cases, the old casing can be pulled and replaced, or a liner installed inside the existing casing. This is complex and not always feasible.

Prevention: Safety Ropes

A proper safety rope should:

• Be stainless steel cable or high-strength poly rope
• Connect directly to the pump body (not the pipe)
• Be secured independently at the wellhead
• Be rated for the pump's weight plus a safety factor
• Be inspected and replaced periodically

Cost of installing a safety rope: $50-150 (during pump installation). Cost of not having one: potentially thousands.
