How long do well pumps last?

Lifespan varies with pump quality, water chemistry, cycling frequency, and usage. Submersible pumps often last many years, but short-cycling, sediment, and electrical issues shorten life. There is no single guaranteed number; good sizing and a healthy pressure tank help.

Can I replace a well pump myself?

Pulling and wiring a well pump involves heavy equipment and electrical work with real safety and contamination risks. This is generally a job for a licensed well or pump professional.

Types of Well Pumps: Submersible vs. Jet (and More)

Submersible and jet pumps dominate residential wells, and depth is the main deciding factor. Here’s how the common types differ.

Quick Answer

Most modern residential wells use a submersible pump that sits down in the well, below the water level. Shallow wells sometimes use a jet pump mounted above ground. The right choice is driven mainly by well depth and the water level, plus your flow and pressure needs. Sizing any pump requires matching flow and total dynamic head to the pump’s performance curve.

The common types

Type	Where it sits	Typical use
Submersible	Inside the well, below water level	Most drilled wells, including deep ones
Shallow-well jet	Above ground	Shallow wells (water near the surface)
Deep-well (convertible) jet	Above ground, with a jet assembly in the well	Deeper wells where a jet is preferred
Hand pump	Above ground, manual	Backup/off-grid access

General guide — your well’s specifics decide

Submersible pumps

Submersible pumps push water up from below the water level and are efficient and quiet because the motor is underwater. They are the default for most drilled wells and can handle significant depth. Because they are down the well, service means pulling the pump — a job for a professional.

Jet pumps

Jet pumps are mounted above ground and use suction. Shallow-well jets work where the water level is near the surface; deep-well jets use a two-pipe system reaching further down. Being above ground makes them easier to access, but suction physics limits how deep a shallow-well jet can lift water.

Depth drives the decision

The static and pumping water levels — how far down the water sits, and how far it drops while pumping — are the key numbers. A professional measures these to recommend a pump type and size.

Sizing comes next

Whatever the type, sizing means estimating your peak flow demand and the total dynamic head the pump must overcome, then matching those to a specific model’s pump curve. Our calculators estimate the targets; a professional confirms against real well data before installation.
