Pressure Tank Service in Jesup, GA
Jesup Well diagnoses waterlogged tanks, replaces failed bladder tanks, and correctly sizes pressure systems for Wayne County well owners — stopping the short cycling that burns out pumps prematurely.
Pressure Tank Diagnosis and Replacement in Wayne County, Georgia
The pressure tank is the buffer between your submersible pump and your household plumbing. Its job is to hold a volume of pressurized water so the pump doesn't start every time a faucet opens. When the tank fails — most commonly when the internal bladder ruptures — the pump starts and stops dozens of times per hour. That short cycling destroys pump motors faster than almost anything else. A pressure tank is an inexpensive component compared to a submersible pump replacement; catching a failed tank early pays for itself many times over.
How Bladder Tanks Work and Why They Fail
Modern residential pressure tanks use a rubber bladder to separate the pressurized air charge from the water. When the pump runs, water fills the lower portion of the tank, compressing the air above the bladder. When a faucet opens, the compressed air pushes water out — the pump doesn't need to run until the pressure drops to the cut-in setting. Bladder failure happens when the rubber membrane cracks from age, mineral exposure (Wayne County's iron-rich Floridan Aquifer water is hard on rubber components), or from being over-pressurized. A ruptured bladder means water fills the entire tank and the air cushion disappears entirely.
Diagnosing a Waterlogged Tank
A waterlogged tank has a distinctive signature. Tap the tank with a knuckle from bottom to top — a healthy tank sounds hollow in the upper portion where the air charge sits. A waterlogged tank sounds solid all the way up. The other indicator is pump behavior: a pump starting and stopping every 5 to 30 seconds almost always means a waterlogged tank. Check the Schrader valve on the tank's air stem with a tire pressure gauge — if water sprays out instead of air, the bladder has ruptured and water has reached the air side. Confirming the diagnosis before replacing is important because short cycling has other causes — a pressure switch set with too narrow a differential, or a leak in the system that exceeds pump flow — and those won't be resolved by replacing the tank.

Correct Tank Sizing for Wayne County Wells
The most common pressure tank installation mistake is undersizing. Homeowners and contractors frequently install the smallest tank that fits the budget — a 20-gallon tank for a well with a pump producing 12 GPM. At that combination, the pump cycles far more often than necessary even with a perfect bladder, because the draw volume is too small relative to flow rate. For typical Wayne County residential wells with 1/2 to 1 HP submersible pumps producing 8 to 15 GPM, a 36 to 86 gallon tank provides adequate draw volume to keep pump starts under 6 per hour at design flow. We size replacement tanks to your pump and system — not to what was there before.
Pre-Charge Pressure and Pressure Switch Settings
A correctly sized tank installed with the wrong air pre-charge performs almost as badly as a waterlogged one. The tank's pre-charge should be set 2 psi below the cut-in pressure switch setting — 28 psi for a 30/50 system, 38 psi for a 40/60 system. At the wrong pre-charge, effective draw volume drops dramatically and cycling increases. We verify and set pre-charge on every installation, and confirm pressure switch cut-in and cut-out settings match the system design. If the pressure switch itself is failing, that's addressed at the same visit — see pump repair for pressure switch service.
Why Choose Jesup Well for Pressure Tank Service
Confirm Before Replacing
We verify the tank is actually the problem — not a pressure switch issue, a system leak, or a pump producing too little flow — before recommending replacement. A misdiagnosed tank replacement doesn't fix the actual problem.
Correct Sizing
We size replacement tanks to your pump's flow rate and system pressure range — not to whatever was installed before. Correct sizing prevents premature short cycling even after the bladder is new.
Pre-Charge Set Correctly
Every installation includes setting the tank pre-charge to the correct pressure for your pressure switch setting. An incorrect pre-charge on a new tank produces the same short cycling as a failed old one — we don't leave without verifying.
Pump Protection
A failed pressure tank is one of the leading causes of premature pump failure in Wayne County. Resolving the tank issue early — before the motor burns from short cycling — is always less expensive than a pump replacement.
How Pressure Tank Service Works
Diagnosis
We check the tank's air stem with a pressure gauge, tap-test for waterlogging, observe pump cycling behavior, and verify pressure switch settings. We confirm whether the tank, the pressure switch, or another system factor is causing short cycling before any work begins.
Tank Sizing & Replacement
We select a correctly sized replacement tank based on pump flow rate and pressure switch settings. The system is shut down, pressure relieved, and the old tank is removed and replaced with the new tank using appropriate fittings and valving.
Pre-Charge Setting & System Test
The new tank's pre-charge is set to the correct pressure for your switch settings. The system is pressurized and pump cycle timing is verified — confirming the pump runs for an appropriate duration before cycling off. We leave when the system is operating correctly.

Pressure Tank Service — Frequently Asked Questions
What is a waterlogged pressure tank?
A waterlogged pressure tank is one where the internal bladder has ruptured. Without the rubber membrane to separate air from water, the tank fills entirely with water and loses its air cushion. With no air buffer, the pump must start every time a drop of water is used — causing short cycling that can run 60+ starts per hour and destroy pump motors in months.
How does short cycling damage a well pump?
A submersible pump motor generates heat during startup — the startup current surge is 3 to 6 times running current. A properly sized pressure tank allows the pump to run for 1 to 2 minutes per cycle. A waterlogged tank causes 60 or more starts per hour. Each start generates heat and electrical stress that accumulates. Motors that should last 12 to 15 years can fail in months under severe short cycling conditions.
What pressure setting should my well pressure tank be set to?
Most residential well systems use a 30/50 psi or 40/60 psi pressure switch — pump turns on at the lower number and off at the upper. The tank's pre-charge air pressure should be set 2 psi below the cut-in setting: 28 psi for a 30/50 system, 38 psi for a 40/60 system. An incorrect pre-charge dramatically reduces the tank's draw volume and increases cycling frequency even with a perfectly intact bladder.
How long do pressure tanks last?
A quality bladder pressure tank typically lasts 8 to 15 years. Lifespan depends on water quality — chlorine and high mineral content degrade rubber bladder material, and Wayne County's iron-rich Floridan Aquifer groundwater can shorten bladder life. Maintaining correct pre-charge pressure and preventing extreme short cycling also extends tank life.
What size pressure tank do I need for my well?
Tank sizing depends on pump flow rate (GPM), desired pump run time per cycle, and pressure range. For a typical Wayne County residential well with a 1/2 to 1 HP pump producing 8 to 12 GPM, a 36 to 44 gallon tank provides adequate draw volume to prevent short cycling. Undersized tanks — a very common installation error — force excessive cycling even with a healthy bladder.
Can I replace a pressure tank myself?
Pressure tank replacement involves shutting off pump power, draining system pressure, removing the old tank, and installing the new one with correct fittings. The critical step that is often done wrong is setting the pre-charge to the correct pressure for the system's pressure switch settings. An incorrectly charged new tank produces the same short cycling as a failed old one. We handle replacement with correct sizing, pre-charge setup, and confirmed system testing included.
