Your shower drops to a trickle. Your pump kicks on every thirty seconds. The pressure gauge swings up and down for no obvious reason. If any of that sounds familiar, your pressure tank is probably the problem.
Across the private well country of southeastern Pennsylvania, from the farmland outside Boyertown and Oley in Berks County to the rolling hills around Chester Springs in Chester County, a failing pressure tank is one of the most common well system complaints we hear. It’s also one of the most disruptive, since it usually shows up as “no water” rather than a polite warning light. The good news is that most pressure tank problems are diagnosable, and quite a few are fixable without replacing the whole tank.
This guide walks well owners across Bucks, Chester, Montgomery, Berks, Delaware, and Lehigh counties through the most common pressure tank problems, how to troubleshoot them yourself, and how to know when it’s time to call in a professional.
In this guide:
What Does a Pressure Tank Actually Do?
Your pressure tank sits between your well pump and your home’s plumbing. It stores a reserve of pressurized water so your pump doesn’t have to switch on every single time someone opens a faucet or flushes a toilet.
Most homes we service throughout Bucks, Chester, Montgomery, and Berks counties rely on private wells, especially in the townships where public water never reached, like the countryside around Oley and Exeter Township in Berks County, or the farmland surrounding Chester Springs and Honey Brook in Chester County. In those areas, a pressure tank isn’t a minor accessory. It’s doing constant, daily work, which is exactly why it tends to be one of the first components to show wear.
5 Common Water Pressure Tank Problems in Southeastern PA
These five issues account for the overwhelming majority of pressure tank service calls we run across the region, whether that’s a rural property in Montgomery County or a well-fed home in the Lehigh Valley near Macungie or Alburtis.
1. Short Cycling
Short cycling is when your pump turns on and off rapidly, sometimes every few seconds. It’s the single most common pressure tank problem we see, and it puts real strain on your pump motor.
The usual cause is a failed bladder inside the tank. Once the bladder tears or loses its seal, water fills the entire tank and there’s no air cushion left to work with. The pump ends up firing constantly just to hold pressure. Left alone, short cycling can burn out a pump, which turns a relatively simple tank repair into a much bigger well system job.
2. Waterlogged Tank
A waterlogged tank is closely related to short cycling. It happens when the air charge inside the tank is lost, usually because the bladder has failed or the air valve, called a Schrader valve and similar to the one on a car tire, is leaking.
If you tap on the side of your tank and it sounds completely solid from top to bottom, with no hollow section near the top, that’s a strong sign it’s waterlogged.
3. No Water or Very Low Pressure
If you’re getting little to no water pressure, the tank may not be the first thing to fail, but it’s usually involved somewhere in the chain. A tank that’s lost its pre-charge air won’t push water through your system the way it should.
Other causes of low pressure include a failing well pump, a clogged sediment filter, or a pressure switch that isn’t triggering the pump correctly. Because these issues overlap so much, figuring out the actual source matters before you spend money on the wrong repair.
4. Pressure Switch Problems
The pressure switch monitors water pressure and tells your pump when to turn on and off. It’s a small, inexpensive component, but a failing one can mimic full tank failure almost exactly.
Pressure switch contacts corrode and burn out over time, especially in homes with hard water or high iron content, both of which show up regularly in well water tested across Berks, Chester, and Montgomery counties. Replacing a pressure switch is relatively inexpensive, so it’s worth ruling out before anyone assumes the whole tank needs to go.
5. Tank Leaks or Corrosion
Steel pressure tanks rust from the outside in, especially in damp basements, crawlspaces, and utility rooms, which describes a lot of the older farmhouses and mid-century homes scattered across rural Bucks and Montgomery counties. A small leak around the tank’s fittings or at its base is a warning sign worth taking seriously.
Corrosion that reaches the inside of the tank can affect your water quality directly. If you notice rust colored water alongside a leaking tank, get it looked at promptly rather than waiting for it to get worse.
Not Sure What’s Actually Wrong?
A quick inspection can tell you whether you’re looking at a switch, a bladder, or a full tank replacement, before you spend money guessing.
Bladder-Style vs. Older Galvanized Tanks
The type of tank sitting in your basement matters a lot for how these five problems play out. Older homes throughout Delaware and Montgomery counties, in particular, sometimes still have the original style of tank installed decades ago.
Bladder-Style (Captive Air) Tanks
A flexible bladder physically separates the air charge from the water, so the pre-charge stays put for years. Not repairable once the bladder fails. The tank itself has to be replaced.
Older Galvanized (Non-Bladder) Tanks
Common in homes built before the 1980s. Air and water share the same space, and the tank needs periodic manual draining to restore the air charge. More prone to waterlogging over time.
How to Troubleshoot Your Pressure Tank
You can run a basic check yourself before calling anyone. Here’s a simple process to work through.
Check the pressure gauge. Look at the gauge on your tank while the system is idle. A healthy system typically holds pressure between 40 and 60 PSI, depending on your settings. If the gauge reads zero or swings erratically, something’s off.
Check the air charge. Turn off power to your pump at the breaker. Open a faucet and let the pressure bleed down to zero. Then use a tire pressure gauge on the Schrader valve, usually on top of the tank. The air pressure should read about 2 PSI below your pump’s cut-in pressure. If you get water instead of air, the bladder has likely failed.
Listen to your pump cycles. Time how long the pump runs between cycles. A healthy pump should run at least one to two minutes per cycle. If it’s cycling every few seconds, you’re dealing with short cycling.
Tap the tank. With the system pressurized, tap along the side. You should hear a hollow section, air, in the upper portion and a fuller sound, water, in the lower portion. If the whole tank sounds solid, it’s likely waterlogged.
If these steps point to a bladder failure, or you’re just not sure what you’re looking at, that’s the right moment to call in a well tank and pump professional rather than keep guessing.
Troubleshooting mistakes to avoid
Repair vs. Replacement: How to Decide
Not every pressure tank problem means you need a new tank. Here’s a simple way to think through the decision.
| Situation | Likely Action |
|---|---|
| Pressure switch failure | Replace the switch |
| Low air charge, bladder intact | Recharge air via Schrader valve |
| Failed bladder, tank under 5 years old | Evaluate warranty; possible repair |
| Failed bladder, tank 7+ years old | Replacement usually makes more sense |
| Corrosion or an external leak | Replacement recommended |
| Short cycling with possible pump damage | Replace tank and assess pump |
Bladder-style tanks, the most common type installed today, are not typically repairable once the bladder fails. The tank itself has to be replaced. The good news is that a well-sized replacement tank, properly installed, should give you 10 to 15 years of reliable service.
Tank sizing matters too. An undersized tank makes your pump work harder and shortens its life. If your current tank was undersized to begin with, replacement is also a chance to right-size the system for your household’s actual water demand, something our well tanks and well pumps team walks through with every homeowner before recommending a replacement.

Water Tank Maintenance Tips for Southeastern PA Well Owners
Pressure tanks don’t need much attention, but a little routine care goes a long way toward avoiding a mid-winter emergency.
If it’s been a while since your last test, our annual well water check-up guide covers what a full inspection actually looks at. This matters just as much for newer wells in growing pockets of western Montgomery County as it does for the older private systems around Quakertown and New Hope in upper Bucks County, where well water testing tends to turn up its own local quirks.
When to Call a Professional
Some pressure tank work is straightforward. Recharging the air pressure, for example, is something a handy homeowner can usually do safely. But there are situations where it’s worth bringing in a licensed well service professional instead of continuing to troubleshoot on your own.
For well owners across southeastern Pennsylvania, our well tanks and well pumps team handles diagnosis, pressure switch replacement, and full tank replacements, and because Dierolf also handles residential plumbing and water treatment, a real technician can flag a related issue, like iron buildup affecting your pressure switch, that a tank-only specialist might miss. If you’re weighing a home purchase on a well, our guide on buying a home with a well in Bucks County covers what to check before closing, pressure tank included.
A pump that’s been struggling for a while is worth a second look too. Our article on the signs your well pump may be failing breaks down when the pump itself, not just the tank, is the real culprit.
According to the Pennsylvania Department of Environmental Protection, private wells aren’t regulated or routinely tested by the state, which means well system maintenance, pressure tank included, is entirely on the homeowner. Penn State Extension offers similar guidance for well owners looking to understand their system before calling for service.

FAQs
How do I know if my pressure tank bladder has failed?
The clearest sign is getting water, instead of air, from the Schrader valve when you check the air charge with the system depressurized. Short cycling, a waterlogged sounding tank, and erratic pressure at the tap are also strong indicators. If any of that sounds like your system, fill out the form on this page and we’ll take a look.
Can I recharge my pressure tank myself?
Yes, if the bladder is still intact. Turn off the pump, bleed pressure to zero, then use a tire pump to add air through the Schrader valve until you reach the correct pre-charge pressure, typically 2 PSI below your cut-in setting. If you get water from the valve instead of air, the bladder has failed and recharging won’t fix it.
How long does a pressure tank last?
Most bladder-style pressure tanks last 10 to 15 years with proper maintenance. Tanks in homes with corrosive water, meaning low pH or high iron, which is common in pockets of Berks and Chester counties, tend to wear out faster. Annual air charge checks and staying on top of your water quality can stretch that lifespan.
What causes a pressure tank to short cycle?
Short cycling is almost always caused by a failed or waterlogged bladder. Once the air cushion is gone, the pump has to switch on constantly just to hold pressure. A faulty pressure switch can cause the same symptom in some cases, which is why a proper diagnosis matters before replacing parts.
Is short cycling bad for my well pump?
Yes. Every time your pump starts, it draws a surge of electricity and puts mechanical stress on the motor. Frequent short cycling significantly shortens pump life. If your pump has been short cycling for weeks or months, it’s worth having a professional check whether it’s already been damaged.
How much does pressure tank replacement cost in Pennsylvania?
Costs vary based on tank size, installation complexity, and whether other components, like the pressure switch or the pump itself, need attention at the same time. We use project-based pricing and give an honest, specific assessment after actually seeing your system. Fill out the form on this page to get a straight answer for your setup.
When should I replace my pressure tank instead of repairing it?
If the bladder has failed, replacement is almost always the right call, since bladder-style tanks aren’t repairable. The same goes if the tank shows corrosion, is more than 10 years old, or was undersized for your home to begin with. Replacement is also a chance to right-size the tank and potentially extend your pump’s life.
A failing pressure tank rarely fixes itself. The sooner you catch the problem, the less likely it is to take your pump down with it.
