What a new well pump costs
This Old House puts the cost of replacing a well pump at $900 to $2,500. It says the price depends on the type of pump, the depth of the well and how hard the install is.
The U.S. Environmental Protection Agency's guide for private well owners, using 2019 data, says a replacement pump is often $1,200 to $1,800.
The pump is only part of the bill. This Old House, pricing pumps at The Home Depot, lists about $200 for a shallow well jet pump and $500 for a submersible pump, before installation.

The Idaho Department of Water Resources keeps Well Driller's Reports, and its well search shows "well size and depth, geology, depth to water, water levels, flow rate". It says the database "contains most of the Well Drillers Reports from July 1987 to current."

Depth matters for the price, so look up your well's report before you talk to a pump business.

What changes the price
- Depth. This Old House says deeper wells take more labor and special equipment to pull and reset a pump.
- Pump type. It says submersible pumps usually cost more to install than jet pumps, because they sit deep in the well.
- Weight and gear. Some pumps weigh more than 100 pounds, and deep submersible pumps need special equipment to pull without damaging the pipe or wiring, This Old House says.
Who handles each part
- The pump and pressure tank: the local well and pump businesses. Look up an electrical license on DOPL's public license search.
- A new well or a deeper one: a licensed driller. IDWR's licensed well driller search finds them by county.
- Panel or circuit work for the pump: the local electricians.
