Why Your Well Pressure Tank Problems Need Immediate Attention
When your pressure tank not working leaves you with inconsistent water pressure or no water at all, you’re dealing with a critical component in your well system. A malfunctioning pressure tank doesn’t just inconvenience your daily routine—it can damage your well pump and waste energy.
Quick Solutions for Common Pressure Tank Issues:
- Low air pressure – Check and adjust air charge to be slightly below the pump’s cut-in pressure
- Waterlogged tank – Replace tank if water comes from the air valve (indicates a ruptured bladder)
- Faulty pressure switch – Clean contacts or replace if burnt or corroded
- Bad check valve – Replace the valve to stop water from draining back into the well
Your pressure tank stores pressurized water and controls when your well pump turns on and off. When it fails, your pump cycles too frequently, leading to premature wear and higher energy use.
Most pressure tanks last for many years, but issues can develop earlier due to sediment buildup, chlorine damage, or simple wear and tear. The good news is that many pressure tank problems have straightforward fixes you can handle yourself with basic tools and safety precautions.
However, some issues require professional attention—especially anything involving electrical components or pump replacement.
Common Signs Your Well Pressure Tank is Not Working
Your well pressure tank quietly works behind the scenes to deliver steady water pressure. But when this essential component starts failing, it sends out clear warning signals.
The most obvious red flag that your pressure tank not working properly is fluctuating water pressure. You might be in the shower when the pressure drops to a trickle, then surges back moments later. This frustrating dance of weak and strong water flow, often accompanied by spitting faucets that spray air with water, tells you the tank isn’t maintaining the steady air cushion needed to push water consistently.
Another telltale sign is pump short-cycling—when your well pump turns on and off much more frequently than normal. A healthy pressure tank should provide a good amount of water flow before your pump needs to kick in. If you notice your pump firing up very frequently instead, that’s a strong signal the tank has lost its ability to hold proper air pressure or water volume.
Listen carefully around your pressure tank area, too. Unusual clicking noises often indicate the pressure switch is rapidly flipping between “on” and “off” because it can’t maintain stable pressure. This constant switching puts unnecessary stress on your entire system.
You might also experience water hammer—jarring banging sounds in your pipes when you suddenly turn off a faucet. A properly functioning pressure tank absorbs these shock waves. When the tank fails, that energy has nowhere to go, causing your pipes to vibrate violently and potentially leading to damage.
Finally, take note of your energy usage. A malfunctioning pressure tank forces your pump to work overtime, cycling constantly or running far more than it should. All that extra pump activity translates directly into higher energy consumption.
Recognizing these warning signs early can save you from bigger headaches. A failing pressure tank doesn’t just inconvenience your daily routine—it can damage your well pump and create significant repairs throughout your water system. If you’re experiencing any of these symptoms, it’s time to investigate what’s happening with your tank.

How to Troubleshoot Your Well Pressure Tank: A Step-by-Step Guide
When you’re dealing with a pressure tank not working properly, a little detective work can prevent bigger problems down the road. Think of it as a health checkup for your well system. But before we start, let’s talk about safety.
Safety First: Preparing for Inspection
Working with well systems means dealing with both pressurized water and electricity. Taking a few simple safety steps upfront will keep you out of trouble.
Turn off the power first—this is non-negotiable. Head to your electrical panel and flip the circuit breaker that controls your well pump to the “off” position. The pump could kick on unexpectedly while you’re working.
Next, depressurize the entire system. With the power off, open any faucet connected to your well and let it run until the water stops. This drains your tank and water lines, removing all built-up pressure.
Don’t forget your protective gear—slip on some work gloves and safety goggles. It might seem like overkill, but you never know when you’ll encounter unexpected splashes or sharp edges.
How to Check and Adjust the Air Pressure
Checking your pressure tank’s air charge is like taking its vital signs; it tells you whether you’re dealing with a simple fix or something more serious. Most pressure tank problems start with incorrect air pressure.
Start by making sure your tank is completely drained of water. With the power off and a faucet open until it stops, you’re ready for an accurate reading. Now, find the air valve—it looks just like the valve stem on a car tire and is usually on top of the tank or along the side.
Grab a standard tire pressure gauge and press it firmly onto the valve stem. The ideal pressure for an empty tank is slightly below your pump’s cut-in pressure. The cut-in pressure is the point at which your well pump turns on to refill the tank. You can determine this by watching your pressure gauge during a normal pump cycle.
If your reading is too low, you can add air using a compressor or a bicycle pump. Go slowly and check frequently. If you have too much pressure, just press the pin in the center of the valve stem to release air until you hit your target.
Diagnosing a Waterlogged Tank and Other Issues
Beyond air pressure, a few simple tests can tell you whether your tank is failing. These checks might seem old-school, but they’re effective.
Tap the tank gently with your knuckles from top to bottom. A healthy, empty tank should give you a hollow sound throughout. If you hear a dull thud, especially toward the bottom, you’re likely dealing with a waterlogged tank where the internal bladder has failed.
The definitive test for waterlogging is to check the air valve for water. When you press your tire gauge against the valve stem, only air should come out. If you see water instead, the internal bladder that separates air from water has ruptured, and the tank needs replacement.
Don’t forget to give your pressure switch a visual once-over. This box, usually mounted on a pipe near your tank, controls your pump. With the power still off, look for obvious trouble signs like burnt contacts, corrosion, or damage. Sometimes what looks like a pressure tank problem is actually a faulty pressure switch.
These diagnostic steps will give you a clear picture of what’s happening with your pressure tank, helping you decide if it’s a quick fix or something more serious.
Common Pressure Tank Problems and How to Fix Them
Now that you know how to safely troubleshoot your system, let’s tackle the most common culprits behind a pressure tank not working properly. The good news is that some of these fixes are surprisingly straightforward.
Fix #1: Incorrect Air Charge
This is the most common issue—and thankfully, often the easiest to resolve. Think of your pressure tank like a tire that’s gone a bit flat. It still works, but not very well.
When your tank has low air pressure, you’ll notice your well pump becomes hyperactive, turning on and off frequently. Your water pressure will feel inconsistent—strong one moment, weak the next. You might even hear your faucets spitting air along with water.
The ideal pressure for your empty tank should be slightly below your pump’s cut-in pressure. This gives the compressed air enough force to push water through your pipes effectively.
Recharging your tank is simple. After following the safety steps—power off, tank drained—check the air pressure with a tire gauge. Too low? Use an air compressor or bicycle pump to add air until you hit the target. Replace the valve cap, restore power, and your pump should settle into a calmer rhythm.
An overcharged tank is also problematic. Too much air pressure reduces the tank’s water storage capacity and can make your system less efficient. If your gauge shows you’ve added too much, simply release some air from the valve until you’re back in the right range.
Fix #2: A Waterlogged Tank
This is a more serious problem. A waterlogged tank means the internal bladder—the flexible membrane keeping air and water separate—has failed. It’s like trying to use a broken balloon to hold air.
The symptoms are hard to miss. Your pump will short-cycle almost constantly, creating a cycle of brief water pressure followed by immediate drops. When you tap the tank, it’ll sound solid instead of hollow. The definitive test? Press the air valve, and if water sprays out instead of air, you have your answer.
What causes bladder failure? Sometimes it’s simply age—the bladder wears out after years of service. Sediment from iron and manganese can coat and stiffen the bladder, making it brittle. Chlorine damage from well shocking or continuous treatment can also cause it to fail prematurely.
Unfortunately, a ruptured bladder isn’t something you can patch up. The tank needs replacement. When the bladder fails, your pressure switch goes haywire, rapidly switching on and off. This constant stress can quickly damage your well pump, making tank replacement urgent. For more insight into why prompt repairs matter, check out our article on Why Timely Well Pump Repair Matters.
Fix #3: A Faulty Pressure Switch
Your pressure switch is the brain of your well system, telling your pump when to work and rest. When this component gets confused, it can mimic pressure tank not working symptoms.
A bad pressure switch creates distinctive problems. Your pump might run constantly, never getting the signal to shut off, which leads to excessive water pressure and energy use. Or, it might not turn on at all, leaving you with no water. Sometimes you’ll get that familiar short-cycling, but the tank itself checks out fine. You might even hear rapid clicking from the switch.
Main culprits cause switch problems. A clogged sensor tube—the small tube connecting the switch to your water line—can get blocked with sediment, preventing accurate pressure readings. Burnt contacts inside the switch can become pitted over time, especially from short-cycling, preventing consistent electrical connections.
When should you clean versus replace? If you suspect a clogged tube, you can carefully remove the switch (power off and system depressurized!) and clear it out. Tapping the switch gently can sometimes free stuck contacts temporarily. However, if the contacts look visibly burnt or pitted, or if cleaning doesn’t solve the problem, replacement is your best bet. Since this involves electrical work, don’t hesitate to call a professional if you’re not comfortable with wiring.

Fix #4: A Failing Check Valve
Here’s a sneaky one. While technically part of your pump system, a failing check valve can make you think your pressure tank not working when it’s actually fine.
A check valve prevents water from flowing back down into your well. When this valve fails, water your pump worked hard to push into your tank slowly drains back where it came from.
The symptoms are telltale: your pump runs constantly because it can never maintain pressure. The pressure slowly drops as water sneaks back into the well, triggering your pump to start again. You might notice low water pressure or complete water loss after periods of non-use, like overnight. Your pressure gauge will show a complete loss of pressure right after the pump shuts off.
Check valves hide in different places depending on your system. A foot valve sits at the bottom of your well’s drop pipe, common with submersible pumps. Jet pumps might have theirs closer to the pump. Some systems include another check valve on the discharge line before the pressure tank.
Diagnosing and replacing check valves, especially foot valves deep in a well, requires specialized equipment to pull the pump. This is typically a job for experienced professionals. For more information on pump-related services, visit our More info about Pump Services page.
When to Call a Professional for a Pressure Tank Not Working
Sometimes the DIY approach has its limits. While we encourage homeowners to understand their well systems, there comes a point where calling a professional is essential. Knowing when to make that call can save you from significant mistakes and dangerous situations.
Tank lifespan is a big factor. Most pressure tanks last for many years. If yours is approaching or past that milestone, replacement is often a better long-term solution than repeated repairs.
The difference between repairable and replacement issues is straightforward. A faulty pressure switch or incorrect air pressure can often be fixed. But when a tank is waterlogged because the internal bladder has ruptured (when water sprays from the air valve), there’s no fixing it. The tank must be replaced.
Here’s where things get serious: electrical work risks. Many pressure tank not working issues involve electrical components like pressure switches or pump wiring. Water and electricity are a dangerous combination. Unless you have extensive experience with high-voltage systems, electrical repairs should always be left to professionals with the proper training and safety equipment.
The importance of professional diagnosis can’t be overstated. What looks like a pressure tank problem could be something else entirely—a plumbing leak, a failing pump, or low water levels in your well. A professional has the diagnostic tools and experience to identify the real culprit.
We’ve seen cases where homeowners replaced a perfectly good pressure tank due to a misdiagnosis. A trained technician performs comprehensive tests, ensuring you’re not replacing parts unnecessarily or missing a more serious underlying issue.

Frequently Asked Questions about Well Pressure Tanks
When homeowners call us about their well systems, we often hear the same concerns. Pressure tanks can seem mysterious until something goes wrong. Let’s clear up some of the confusion with answers to common questions.
Why is my well pump running constantly?
A constantly running pump is working too hard and using excess electricity. This problem often points back to your pressure tank not working as it should, though a few other culprits might be to blame.
Waterlogged pressure tanks are the biggest offenders. When the internal bladder fails, your tank loses its air cushion. The pressure drops the instant you use water, and your pump scrambles to keep up by running non-stop.
Your pressure switch might also be the troublemaker. If its electrical contacts are burnt or the sensing tube is clogged, it might not tell the pump to shut off.
Don’t overlook sneaky leaks. Even a small drip in your plumbing or a failing check valve that lets water drain back into the well can keep your system from holding pressure. Your pump ends up trying to fill a system that’s constantly losing water.
Sometimes the problem is deeper. If your well’s water level has dropped, your pump might be pulling in air, making it impossible to build proper pressure.
How do I know what my pressure switch setting is?
Understanding your pressure switch settings helps everything run smoothly. The easiest way to find out is to watch your pressure gauge during a normal cycle. Turn on a faucet and watch the gauge. The moment your pump kicks on, note that pressure reading—that’s your cut-in pressure. When it shuts off, that’s your cut-off pressure.
Most homes run on common pressure settings designed to provide good water pressure while protecting your plumbing.
Here’s the crucial part: your empty pressure tank’s air pressure should be set slightly below your cut-in pressure. This relationship is what makes the system work harmoniously.
Can a faulty pressure tank damage my well pump?
Absolutely. A failing pressure tank can lead to the failure of your well pump. We’ve seen this happen countless times, and it’s often preventable.
A healthy pressure tank acts as a shock absorber for your well pump, storing pressurized water to handle small demands without starting the pump. When your pressure tank not working correctly, your pump loses this protection.
Short-cycling becomes the pump’s worst enemy. Instead of running for a steady cycle periodically, a pump with a bad pressure tank might start and stop an excessive number of times a day. Every startup creates electrical and mechanical stress.
The constant starting can overheat the motor, burn out electrical components, and put tremendous strain on the pump’s internal parts. A pump that should last for many years might fail much sooner under this abuse.
Your pressure tank isn’t just a storage container—it’s your pump’s bodyguard. When that bodyguard fails, your pump takes a beating that significantly shortens its life. Maintaining your pressure tank is really about protecting your well pump.
Conclusion
