Submersible Well Pump Replacement Cost

Submersible pumps sit down inside the well casing and are the standard for the large majority of residential wells. Because replacing one means pulling the full drop-pipe and wire assembly, cost tracks depth closely — here's what that looks like by horsepower and by depth.

By horsepower (at a typical 150 ft depth)

Horsepower	Pump unit	Labor	Total installed
0.5 HP	$400–$700	$825–$1,650	$1,225–$2,350
0.75 HP	$500–$900	$825–$1,650	$1,325–$2,550
1 HP	$600–$1,200	$825–$1,650	$1,425–$2,850
1.5 HP	$900–$1,800	$825–$1,650	$1,725–$3,450
2 HP	$1,200–$2,500	$825–$1,650	$2,025–$4,150

By depth (at 1 HP)

Well depth	Pump unit	Labor	Total installed
50 ft	$600–$1,200	$600–$1,200	$1,200–$2,400
100 ft	$600–$1,200	$600–$1,200	$1,200–$2,400
150 ft	$600–$1,200	$825–$1,650	$1,425–$2,850
200 ft	$600–$1,200	$1,050–$2,100	$1,650–$3,300
300 ft	$600–$1,200	$1,500–$3,000	$2,100–$4,200
400 ft	$600–$1,200	$1,950–$3,900	$2,550–$5,100

What moves the price beyond this table

• Pressure tank — if yours is old or waterlogged, replacing it alongside adds $800–$1,500 but saves a second service call.
• Control box — for 3-wire pumps, a worn or corroded box adds $150–$600 and is worth replacing alongside the pump.
• Well casing diameter and access — a narrow or hard-to-reach wellhead can add labor time not captured in a national average.
• Local labor rates — well contractor rates vary meaningfully by region; these ranges are national.
