A pressure tank is the buffer between a well pump and every opened fixture: it releases stored water before the pump starts again. The useful sizing number is drawdown at the home’s pressure-switch setting, not simply the tank volume printed on the label.

A pressure tank works with your well pump to maintain consistent water pressure throughout your plumbing system. Pressure tanks store pressurized water and reduce how often your well pump turns on and off.

When you turn on a faucet, the tank releases stored water first before the pump kicks in to refill it. This system protects your pump from excessive wear while ensuring you have water pressure when you need it.

The tank contains a bladder or diaphragm that separates water from compressed air to maintain proper pressure levels. Tank size and pre-charge pressure are the most important factors when choosing a pressure tank.

The tank must be large enough to meet your household’s water demands without causing the pump to cycle too frequently. Pre-charge pressure should match your system’s cut-in pressure to work properly with your pressure switch.

Buying Guide

Tank size on the label isn’t the number that decides how your pump behaves — drawdown is. Drawdown is the volume of water a tank actually releases before the pump has to switch back on, and it moves with pre-charge pressure as much as with gallons: among the 20-gallon tanks in this list, the Red Lion RL20A is factory pre-charged to 20 psi and posts a 7.2-gallon drawdown at a 30/50 psi switch setting, while the Amtrol WX-202 is pre-charged to 38 psi and posts 6.2 gallons at that same switch setting. Every tank here uses a bladder or diaphragm to keep that pre-charged air separated from your water, and that pre-charge has to be matched to your own pressure switch’s cut-in point, not left at the factory number — get it wrong and the tank does less of the work, so your pump short-cycles more and wears out sooner.

Tank Size

Compare usable drawdown rather than nominal gallons. The page’s two 20-gallon examples illustrate the difference: the Red Lion RL20A lists 7.2 gallons at 30/50, while the Amtrol WX-202 lists 6.2 gallons at the same switch setting.

Pressure Rating

Match the tank to the pump switch, commonly 30/50 or 40/60. The first number is cut-in pressure, when the pump starts; the second is cut-out pressure, when it stops and the tank is full again.

Construction Materials

Steel tanks offer a lower-cost shell but need protection against corrosion, while fiberglass avoids rust at a higher purchase price. Composite construction is another corrosion-resistant option; compare the protective lining and service access as well as the exterior material.

Pre-Charge Pressure

Set the air pre-charge to the pressure switch’s cut-in arrangement before putting the tank into service. Leaving a 20 psi or 38 psi factory setting unchanged when the switch calls for something else reduces drawdown and can bring back short cycling.

Warranty and Certifications

Compare the 5-10 year warranty range shown here with the parts actually covered, then check the applicable NSF drinking-water standard. Pump compatibility still depends on pressure range and connection layout, not brand name alone.

Frequently Asked Questions

How do pump flow and pressure-switch settings determine pressure-tank drawdown?

Start with the pump’s flow rate and the peak demand from fixtures and appliances that may run together. Then compare tank drawdown at the actual cut-in and cut-out settings so the pump gets an adequate rest between starts.

The pump’s flow rate determines the minimum tank size you need. A 10 GPM pump typically requires at least a 20-gallon tank.

Your pressure switch settings affect tank performance. Higher pressure differentials allow smaller tanks to work effectively.

Adding a margin above the calculated size can help prevent undersizing issues as water usage grows.

How often should I replace my well pump pressure tank for optimal performance?

Most pressure tanks last 8 to 12 years with proper maintenance. Actual lifespan depends on cycling frequency, water quality, and bladder design.

The bladder inside typically fails before the tank itself. Steel tanks may develop rust after 6 to 8 years in areas with high humidity.

Annual checks for wear are a common maintenance step. That includes testing air pressure and inspecting for corrosion.

Water quality affects tank life significantly. Hard water or high iron content can reduce the lifespan by 2 to 3 years.

Can you explain how to properly set up a new pressure tank in a well pump system?

Set up begins with turning off power to the pump and draining the old system. Safety comes first in any installation.

The new tank needs proper air pressure before connecting to water lines. A common target is 2 PSI below the pressure switch cut-in pressure.

The tank should sit on a level, stable surface near the pressure switch. It also needs to remain accessible for future maintenance.

All connections require pipe thread compound or Teflon tape. Leak checks should happen before restoring power to the system.

What are the signs that indicate my pressure tank may be failing and requires attention or replacement?

Short pump cycles are one of the most common early warning signs. The pump turns on and off rapidly instead of running steadily.

Water hammering in pipes indicates bladder failure inside the tank. You might hear banging sounds when faucets turn off quickly.

Waterlogged tanks lose their ability to maintain pressure. The gauge drops quickly after the pump stops running.

Rust stains around the tank base suggest internal corrosion. This typically means the steel tank needs immediate replacement.

How does the quality of different brands like Amtrol and Water Worker compare for well pressure tanks?

Amtrol tanks use a heavy-duty butyl rubber bladder that resists bacteria growth. That material is commonly marketed as longer-lasting than standard rubber versions.

Water Worker tanks feature a polypropylene liner that prevents corrosion. Their steel construction typically handles higher pressures well.

Amtrol tanks cost 15% to 20% more than Water Worker models. The price difference reflects the premium bladder materials used.

Amtrol’s Well-X-Trol residential tanks carry a 7-year limited warranty, while Water Worker’s residential tanks carry a 5-year warranty. Choice should come down to pressure rating, drawdown capacity, and tank dimensions.

What is the process for troubleshooting common issues with well pump pressure tanks?

Troubleshooting usually starts with checking the air pressure in the tank using a tire gauge. Low air pressure causes many performance problems.

The pressure switch may need adjustment if cycles are too short or long. Check the cut-in and cut-out pressures during operation.

Inspect all pipe connections for leaks that reduce system pressure.

A waterlogged tank may require bladder replacement or complete tank replacement. One common check is tapping the tank sides and comparing hollow and solid sections.
