Pressure Tank Repair & Replacement
A lot of what looks like a failing well pump is actually a tired pressure tank — and it's usually a cheaper fix.
Request ServiceThe pressure tank is the part of your well system most homeowners have never thought about — until it fails, at which point it can look exactly like a pump problem. Inside every pressure tank is an air-filled bladder that keeps water pressurized between pump cycles. When that bladder ruptures or the tank loses its air charge, the tank fills entirely with water, a condition called waterlogging.
A waterlogged tank forces the pump to cycle on and off far more than it should — sometimes every few seconds — which is exactly the kind of stress that burns out a perfectly good pump motor. Catching a tank problem early protects the pump; catching it late usually means replacing both.
Pump or tank? A few tells
Rapid, repeated cycling — the pump kicking on and off every few seconds even with no water running anywhere in the house — is one of the more reliable signs the tank has waterlogged rather than the pump itself failing. A healthy tank should let the pump cycle a moderate, predictable number of times per day.
Pressure that pulses or fluctuates between strong and weak, rather than staying steady, also points toward the tank. A pump that's simply worn out tends to show up as a slow, steady decline in pressure over weeks or months rather than sudden pulsing.
Repair or replace?
A tank's air charge can sometimes be restored if the bladder itself is still intact — a quick check with a tire-pressure-style gauge at the tank's air valve tells us which situation we're dealing with. If the bladder has actually ruptured, the tank needs to be replaced; there's no reliable repair for a torn bladder.
Replacement tanks get sized to your household's water demand and pump cycling needs, not just swapped for whatever was there before — an undersized tank leads right back to short-cycling.
A healthy pressure reading
Most residential systems are set to run between 40 and 60 PSI. The gauge on top of your tank or pressure switch is worth glancing at occasionally — a reading well outside that range, even before other symptoms show up, is worth having checked.

Frequently asked questions
How long do pressure tanks last?
Most bladder-style pressure tanks last 10-15 years depending on water quality and how much the system cycles. Acidic groundwater, common in parts of the Piedmont, can shorten that lifespan.
What does a waterlogged tank sound like?
The clearest sign is the pump switching on and off rapidly and repeatedly, sometimes every few seconds, even when nothing in the house is using water.
Can I fix a pressure tank myself?
Checking the air charge at the top valve with a standard tire gauge is something many homeowners can do safely. Diagnosing a ruptured bladder and replacing the tank involves shutting down and draining the system correctly, which is easy to get wrong.
Will a bad pressure tank damage my pump?
Yes — that's the main reason to address it early. A waterlogged tank forces the pump to short-cycle, and short-cycling is one of the most common causes of premature pump motor failure.
