Well pressure tank replacement cost: $500–$1,800 installed
Replacing a well pressure tank costs $500–$1,800 installed, on the national rates we compiled for a 20 to 44 gallon tank and switch. A plumber-installed replacement runs $800–$1,800 all-in, while drillers in New York, New Mexico and Arizona list starting prices near $500. Labor alone runs $200–$500, and a difficult install can reach about $3,500.

What the price covers
A replacement means draining and disconnecting the old tank, setting the new one, setting its air charge to match the pressure switch, and reconnecting the plumbing. Water Well Drilling Weatherford in Texas prices tank replacement at $800–$1,800 installed and a new pressure switch at $150–$300. It puts difficult installs, like a tank in a tight crawlspace or one that needs new piping, at up to about $3,500.

Published prices by state
Drillers who publish a tank price tend to list a lower floor than plumbers do, because they often replace the tank on a call that is already on site. Each figure below is one company's or one contract's price, not a state average.

|---|---|---|
| Arizona (Kingman) | $500–$1,200 | A-1 Arthur's Well Service |

| New Mexico (Santa Fe) | $500–$1,800 | Boylan Water Well Service, 2026 |
| Ohio (Mount Gilead), tank and switch | $500–$2,000 | K & B Water Well Drilling |

Tank size and price
A bigger tank stores more water between pump starts and costs more to buy and set. The clearest size comparison we found is a 2023 Minnesota state contract, which priced an installed 34 gallon tank at $1,000 and a 62 gallon tank at $1,450. Most residential replacements in the published prices above are 20 to 44 gallon tanks.
Replacing the pump at the same visit
One supplier puts a pump and tank done together at $2,500–$5,000 or more. If the pump is old and the tank has failed, pricing both on one call saves a second trip. See the well pump replacement cost guide for the pump side, and the quote checklist for what an itemized quote should show.

In a new well
On a new well the tank and switch are one line of the system. The calculator prices them with the state band where one exists and the national $500–$1,800 band elsewhere.

Common questions
How much is a pressure tank without installation?
The equipment is the cheaper part. Bob Vila lists pressure tanks at $100 to $700, and labor on a replacement runs $200 to $500 on one supplier's figures. The installed total of $800 to $1,800 for a plumber's job also covers fittings, a switch where needed, and setting the air charge.
Should the pressure switch be replaced with the tank?
Many installers replace them together, since the switch sits on the same fittings and has to be set to match the new tank's air charge. A pressure switch alone runs $150 to $300 installed on one Texas driller's price list, so it adds little to a tank job that is already under way.
Why do quotes for the same tank differ so much?
Access and who does the work. Drillers in Arizona, New York and New Mexico list replacements from about $500, while plumbers run $800 to $1,800 all-in. A tank in a tight crawlspace or one that needs new piping can reach about $3,500, on one Texas driller's figures.
