The tank that protects your pump
The pressure tank is the quiet workhorse of a well system. It holds a cushion of pressurized water so that every time you open a tap, water flows without the pump kicking on for a single glass. That cushion is what lets the pump rest between draws. When the tank fails, the pump loses its buffer and starts cycling on and off rapidly, which is the fastest way to wear out a pump motor. A $1,000 tank problem, left alone, becomes a $1,800 pump problem.
That is why pressure tank service is one of the most valuable calls a well owner can make. It is often the real cause behind symptoms people blame on the pump, and it is cheaper to fix. This site connects Ocala and Marion County homeowners with local well pros who check the tank before condemning the pump.
Signs your pressure tank is failing
A pressure tank holds a charge of air above the water. Over time that charge can leak out, leaving the tank waterlogged, meaning full of water with no air cushion left. The symptoms are distinctive:
- The pump short-cycles. It clicks on and off every few seconds when you run water. This is the classic waterlogged-tank symptom and the most damaging to the pump.
- Pressure surges or stutters. Water pressure that pulses instead of holding steady points to a lost air charge.
- The tank feels full and heavy. A healthy tank has an air pocket; a waterlogged one is heavy all the way up and sounds solid when tapped.
- Rapid pressure drop. Pressure that falls the instant you open a tap, then triggers the pump immediately, means the tank is no longer storing a reserve.
- Water around the base or rust. A cracked bladder or a corroded tank shell that is leaking is at the end of its life.
A pressure tank typically lasts 5 to 15 years per PVC Fittings Online, shorter than the pump in many cases. If your tank is in that age range and the pump is short-cycling, the tank is the first thing to check.
Repair or replace the tank
Not every tank problem means a new tank. Sometimes the air charge has simply bled down and can be recharged to the correct pressure, or the pressure switch that works with the tank needs adjusting or replacing. A pro checks the air charge and the bladder first. If the bladder has ruptured or the tank shell is corroded or leaking, replacement is the fix, because a failed bladder cannot be repaired.
When replacement is needed, HomeGuide's 2026 data puts the job at $800 to $1,500 including the tank and labor, averaging around $1,000, with labor by itself running $250 to $500. Tank size matters: a larger tank costs more up front but lets the pump run less often, which extends the pump's life. A pro sizes the tank to your pump and household demand rather than just matching whatever was there.
| Pressure tank service | Typical cost (HomeGuide 2026) |
|---|---|
| Recharge air / adjust pressure switch | Often part of a service-call diagnosis |
| Labor to replace the tank | $250 to $500 |
| Full tank replacement, tank plus labor | $800 to $1,500 (avg $1,000) |
Why fixing the tank protects the pump
Short-cycling is not a cosmetic problem. Every time a pump starts, the motor draws a heavy surge of current and the components take a jolt. A pump designed to start a few dozen times a day may cycle hundreds of times a day when the tank is waterlogged. That accelerated wear is exactly how a pump that should last 8 to 15 years fails in far less. Replacing a $1,000 tank to save an $1,800 pump is one of the clearest value calls in well ownership, which is covered further on our pump replacement page.
If your pump is clicking on and off constantly, do not wait. It is one of the few well problems where a delay directly shortens the life of the most expensive component in the system. A quick tank diagnosis, whether it ends in a recharge, a switch, or a new tank, is cheap insurance. See our well pump repair page for the related switch and valve repairs that often go with a tank service.
Frequently asked questions
How much does it cost to replace a well pressure tank in Ocala?
HomeGuide's 2026 data puts a full pressure tank replacement at $800 to $1,500 including the tank and labor, with an average around $1,000 and a minimum of about $450. Labor by itself runs $250 to $500. Tank size and the condition of the switch and fittings affect the final price.
Why does my well pump turn on and off constantly?
The most common cause is a waterlogged pressure tank that has lost its air charge, so the pump has no reserve to draw from and cycles rapidly. A failing pressure switch can cause the same thing. Both are cheaper to fix than the pump, and fixing them protects the pump from the wear that rapid cycling causes.
Can a pressure tank be repaired, or does it need replacing?
Sometimes the air charge can be recharged to the correct pressure, or the pressure switch needs adjusting or replacing, and no new tank is needed. But if the internal bladder has ruptured or the tank shell is corroded or leaking, the tank has to be replaced, because a failed bladder cannot be repaired.
How long does a well pressure tank last?
PVC Fittings Online reports a typical well pressure tank lasts 5 to 15 years. That is often shorter than the pump, so a short-cycling pump on an older tank usually points to the tank as the culprit. Age plus short-cycling is the signal to have it checked.
Is a bad pressure tank really bad for the pump?
Yes. A waterlogged tank makes the pump start hundreds of times a day instead of a few dozen, and every start puts a heavy surge on the motor. That accelerated wear can cut a pump's life dramatically, which is why replacing a roughly $1,000 tank to protect a roughly $1,800 pump is such a clear value call.
What size pressure tank do I need?
The right size depends on your pump's output and how much water your household draws at once. A larger tank costs more up front but lets the pump run less often, which extends pump life. A local pro sizes the tank to your system rather than just matching whatever tank was there before.
