Ready to Install a New Pressure Tank?
Talk to a local plumber about sizing and installing the right tank for your well system.
Call 1-844-853-7355Larger tanks cost more both to purchase and install. A 20-gallon tank is straightforward to handle alone. An 86-gallon tank is heavy and awkward, often requiring two people and more time to position and connect.
A pressure tank in an open basement installs quickly. A tank in a crawl space, closet, or utility room with limited access takes longer and costs more in labor. Some difficult installations require partial disassembly of surrounding fixtures.
If the new tank uses a different connection size or the existing piping is corroded and needs replacement, additional plumbing work adds $100-400 to the total. Always ask the plumber to inspect the surrounding pipe condition before starting.
A new installation where no pressure tank previously existed requires running new pipe connections and sometimes relocating or adding shutoff valves. This adds $150-400 compared to a straight tank swap.
Pressure tank replacement is one of the most beginner-friendly well system repairs. You save $100-300 in labor by doing it yourself. The job requires basic plumbing skills, a pipe wrench, Teflon tape, and a tire gauge.
Steps: shut off pump, drain system pressure to zero, disconnect old tank at the fitting, thread new tank on with Teflon tape, set pre-charge to 2 PSI below cut-in, restore power, test. Total time: 45-90 minutes.
Hire a plumber if: the tank is in a difficult location, the surrounding piping needs work, or you are not comfortable with plumbing connections.
Always size correctly before purchasing. The most common and costly mistake is replacing a failed tank with the same undersized model that caused the problem. Use our free sizing calculator to get the right size for your pump GPM and pressure switch settings. For general guidance on maintaining your private well system, see the EPA's private wells overview.
A brand new installation where no tank previously existed typically runs $400-900 total, higher than a straight swap because it requires running new pipe connections and often adding shutoff valves. If piping modifications are also needed, total cost can reach $600-1,200.
Most plumbers price pressure tank installation as a separate job with its own labor estimate rather than bundling it into a standard service call fee, since the work involves draining the system, disconnecting old lines, and pressure testing the new tank. Expect a dedicated quote rather than a flat trip charge.
Yes, for a straightforward tank swap in an accessible location. It is one of the most beginner-friendly well system repairs, requiring basic plumbing skills, a pipe wrench, Teflon tape, and a tire gauge, and saves $100-300 in labor. Hire a plumber if the tank is in a tight space, the piping needs work, or you are not comfortable with plumbing connections.
Yes. Larger tanks like an 86-gallon model are heavy and awkward to maneuver, often requiring two people and more time to position and connect than a 20-gallon tank, which adds to the labor portion of the bill even before counting the higher tank price itself.
Replacing a failed tank with the same size and model that caused the original problem. If the old tank was undersized, swapping in an identical one just sets up the next short-cycling failure. Always confirm the correct size for your pump's GPM and pressure switch setting before buying, rather than matching what was already installed.
An undersized tank causes low pressure, short cycling, and early pump failure. Check yours free in 2 minutes.
