How it works
Well pump replacement runs $1,200–4,500: the pump itself is $500–1,100, but depth is the price driver — pulling and resetting hundreds of feet of pipe needs a pump rig and crew, billed by depth.
The economic move: if the pump is 10+ years old and the rig is already on site, replace the pressure tank, drop pipe, wire and controls too. Each of those failing a year later means paying the pull/set labor all over again.
Match horsepower to depth and demand: 1/2 HP suits wells under ~150 ft with normal household use; deeper wells and irrigation need 3/4–1.5 HP. Undersized pumps run constantly and die young; oversized ones short-cycle.
Frequently asked questions
How much does well pump replacement cost?
$1,200–2,500 for shallow wells, $2,500–4,500 for deep ones. Pump: $500–1,100. Pull/set labor: $600–1,600 by depth. Extras (tank, wire, pipe): $500–1,500.
How long do well pumps last?
Submersible: 10–15 years. Jet pumps: 8–12. Hard water, sediment, short-cycling and lightning shorten life. A 12-year-old pump owes you nothing — replace proactively.
What are signs my pump is failing?
Flickering water pressure, pump running constantly, air sputtering from taps, tripped breakers, or steadily declining flow. Any two together = call a well pro.
Submersible vs jet pump?
Submersible (in the well): efficient, quiet, lasts longer — standard for wells over 25 ft. Jet (above ground): cheaper, easier to service, only for shallow wells.
Can I pull the pump myself?
Under 100 ft with help and a pump-puller tool, maybe. Deeper: no — hundreds of feet of water-filled pipe weigh hundreds of pounds and need a rig. This is pro work.
Should I replace the pressure tank too?
If it is 10+ years old or waterlogged (pump short-cycles), yes — $400–600 while the crew is there. A bad tank kills new pumps fast.
What size pump do I need?
Depth + household demand: 1/2 HP to ~150 ft, 3/4 HP to ~250 ft, 1+ HP deeper or with irrigation. Your well pro sizes from the well log — ask for it.
Does homeowners insurance cover it?
Sudden failure (lightning strike): often yes. Wear and tear: no. A $200 whole-house surge protector is cheap pump insurance.
How do I find my well depth?
The original well log (often filed with the county/state), the well cap tag, or your well company's records. Depth matters for every quote — find it before calling.
What maintenance does a well need?
Yearly: water test (bacteria, nitrates), check pressure tank precharge, inspect the cap seal. Every 3–5 years: pro inspection. Keep chemicals and septic 50–100 ft from the wellhead.
