- Short cycling
- Leaking or rusted tanks
- Lost air charge
What a pressure tank does
Your pressure tank holds a reserve of water under air pressure. When you open a faucet, the tank supplies water first, and the pump only starts when the pressure drops to the switch’s cut-in setting. That lets the pump run in longer, less frequent cycles, which is easier on the motor and the pressure switch.
Most modern tanks have a rubber diaphragm or bladder that keeps the air and water apart. Amtrol’s Well-X-Trol is a familiar example. Older homes may still have a plain steel tank where air and water mix, which slowly loses its air over time.
Signs your pressure tank is failing
- Short cycling: the pump starts and stops every few seconds while water runs. You can often hear the pressure switch clicking.
- Pressure that swings up and down quickly at the faucet or shower.
- Water coming out of the air valve on top of the tank. That usually means the diaphragm or bladder has failed.
- Rust, sweating, or a leak at the bottom or seams of the tank.
- A tank that sounds solid all the way to the top when tapped. A healthy tank sounds hollow near the top.
Why it matters: Amtrol lists rapid pump cycling and low system pressure as signs a tank needs attention. Every start puts wear on the pump motor and switch contacts, so a bad tank can shorten pump life.
How pre-charge is checked
Bladder and diaphragm tanks are filled with air at the factory, called the pre-charge. Amtrol’s guidance is to set it about 2 psi below the pressure switch’s cut-in pressure, measured with the pump off and the water pressure drained to zero. For example, a 40/60 switch would typically pair with a tank pre-charge around 38 psi.
If you’re comfortable doing it, the check works like this: switch the pump breaker off, open a faucet until the water stops and the gauge reads zero, then use a tire gauge on the air valve at the top of the tank. Don’t remove any covers or touch the pressure switch.
If water comes out of the air valve, or the tank won’t hold air, stop. The bladder has likely failed and the tank usually needs to be replaced. Adding air won’t fix that for long.
Repair or replace?
| Situation | Typical outcome |
|---|---|
| Pre-charge is low, bladder intact | Recharge to the correct pressure and look for the cause of the loss |
| Water at the air valve or a tank that won’t hold air | Replace the tank |
| Rusted, sweating, or leaking tank shell | Replace the tank |
| Old steel tank that keeps waterlogging | Replace with a diaphragm or bladder tank, or service the air control |
| Tank is fine but the pump still cycles | Check the pressure switch, check valves, and leaks elsewhere |
When a tank is replaced, contractors often replace the tank tee, pressure gauge, and pressure switch at the same time because they’re inexpensive and already disconnected. Tank size also matters. A contractor sizes the tank to your pump’s flow rate so the pump gets an adequate run time each cycle.
What does a pressure tank replacement cost?
We don’t publish local prices. As a national reference, HomeAdvisor lists pressure tank replacement at roughly $500 to $1,000. Tank size, brand, and whether other parts are replaced at the same time all affect the final price. Your contractor should quote it before starting work.
Pressure tank FAQ
How long does a well pressure tank last?
It depends on the tank, water quality, and how hard the system works. Watch for the warning signs above rather than going by age alone, and have the pre-charge checked if your pump starts cycling more often.
Can I just add air to my pressure tank?
On a bladder or diaphragm tank, adding air only helps if the bladder is intact and the pre-charge was simply low. If water comes out of the air valve, the bladder has failed and the tank needs replacing.
What is a waterlogged pressure tank?
It means the tank has lost its air cushion and is mostly full of water. Without that air, there is almost no stored water, so the pump turns on and off every few seconds. This is called short cycling.
Why is my pressure tank making the pump click on and off?
Rapid clicking is the pressure switch turning the pump on and off. The most common cause is a tank that has lost its air charge, but a failing switch or a leak in the plumbing can do it too.
