Understanding Well Pump Replacement Cost
A well pump is the heart of your home's water system if you're not connected to municipal water. When your pump fails, you lose all water supply to your home—making prompt replacement essential. Well pump replacement costs $800-$2,500 for most installations, though deep wells can cost $3,500-$5,000+.
Understanding well pump types and their costs helps you budget appropriately and make informed decisions when replacement becomes necessary.
Types of Well Pumps
Shallow Well Jet Pumps
Cost: $200-$500 for pump, $400-$1,000 installed
