How much does a pressure tank replacement cost?

Pressure tank replacement costs depend on tank size and your system's pressure requirements, but most residential replacements are a straightforward, same-day job. A technician can give you a firm, written estimate after a quick assessment of your current setup.

How long does a pressure tank last?

A quality pressure tank typically lasts 10 to 15 years, though waterlogged tanks or ones exposed to high mineral content can fail sooner. Well-X-Trol tanks, which K & K stocks and installs, carry a 7-year manufacturer's warranty. Regular pressure checks can help catch a failing tank before it causes bigger problems.

What size pressure tank do I need?

Pressure tank sizing depends on your pump's flow rate, household or business water demand, and how often you want the pump to cycle on and off. An undersized tank causes the pump to short-cycle and wear out faster, while an oversized tank adds unnecessary cost. K & K's technicians size each tank to match your specific pump and system rather than defaulting to one standard size.

Should I repair or replace my pressure tank?

K & K Well Drilling replaces pressure tanks rather than attempting piecemeal repairs, since a tank that's waterlogged, rusted, or losing its air charge is typically nearing the end of its service life across the board. Replacing it outright with a quality tank sized correctly for your system is more reliable than a temporary fix.

Pressure Tank Installation & Replacement Across Northern Illinois

K & K Well Drilling, Inc. has installed and replaced well pressure tanks for homeowners and businesses since 1961. A properly sized pressure tank keeps water flowing evenly between pump cycles, and a failing one is one of the most common reasons for weak, surging, or inconsistent water pressure.

What Does a Pressure Tank Do?

A pressure tank stores pressurized water so your pump doesn't have to switch on every time you turn on a faucet. Without a functioning tank, the pump would cycle on and off constantly, which shortens its lifespan and causes uneven water pressure throughout the house. Most residential tanks use a rubber bladder or diaphragm to separate the stored water from a cushion of compressed air, and that air charge is what pushes water through your pipes between pump cycles. A failing tank often shows up as a pump problem even when the pump itself is fine, which is why tank condition is one of the first things a technician checks during a pressure complaint.

Pressure Tanks for New Well Construction

If you're drilling a new well, a properly sized pressure tank is part of the system from day one, not an afterthought. K & K includes tank selection and installation as a standard part of every new well drilling and pump installation project, so you're not left sourcing and sizing a tank separately after the fact. We size the tank to your pump's flow rate and expected household or business demand before it's ever installed, which helps avoid the short-cycling and premature pump wear that come with an undersized tank.

Signs Your Pressure Tank Needs Replacing

If you already have a well system, watch for these signs that your existing pressure tank is failing:

• Pressure that surges and drops repeatedly, even with a healthy pump.

• The pump short-cycling, turning on and off in rapid bursts.

• Visible rust, corrosion, or moisture pooling around the tank.

• A waterlogged tank that feels heavier than it should or sounds full of water when tapped.

• A noticeable drop in water pressure throughout the house.

Signs Your Pressure Tank Needs Replacing

K & K Well Drilling fully stocks and installs Well-X-Trol pressure tanks. In our experience, the manufacturer, Amtrol, Inc., produces one of the most dependable tanks on the market, backed by an industry-leading 7-year manufacturer's warranty. We install Well-X-Trol as our standard recommendation for most residential and commercial installations. Tank size is matched to your pump's flow rate and your household or business water demand, an undersized tank causes premature pump wear, while an oversized one adds unnecessary upfront cost without a meaningful benefit.
