Total water pump replacement and labor costs can range anywhere from $1,000 up to $4,000 (on the extreme end), says Nate Hommel of Always Pure Well Drilling in Toms River, New Jersey. The cost of the pump generally accounts for 75 percent of the total cost of the job. Here are some examples of cost from Hommel (prices do not reflect tax):
4-inch well pump: ~ $1,000 from Always Pure Well Drilling.
Depending on the area, removing and replacing a well pump takes 45-90 minutes.
Larger well pumps cost more and require more labor to replace. Total job costs can range from $1,000-$3,000 for 4-inch, 6-inch, and 8-inch diameter wells. A replacement job totaling $3,000 would be for a big well system, says Hommel.
Replacing a convertible jet pump (housed above ground): ~ $1,000 from Always Pure Well Drilling.
