Pressure Switch Replacement in St. Charles, MO
The pressure switch tells the pump when to start and stop, typically at 30/50 or 40/60 psi. Pitted contacts, insect nests and a clogged sensing nipple are frequent causes of failure in well houses. We replace worn switches with Square D or similar models and clean or replace the nipple below it. A low-pressure cutoff switch can also be added to stop the pump if the well runs dry. We set the switch to match your new tank's pre-charge.

Emergency Pressure Tank Replacement in St. Charles, MO
A ruptured tank can leave you with no water or a pump that never shuts off, which can burn up the motor fast. If the pump is running nonstop, turn off its breaker and call (816) 330-2338. We carry standard tank sizes and fittings for same-day replacement. Once water is restored, we test the pump's amp draw to make sure it was not damaged. Fast action can save you the cost of a new pump.
Pressure Tank Sizing and Upsizing in St. Charles
Many older systems have a tank that is too small for the pump, so the motor starts every time someone washes their hands. Tank size is based on drawdown, which is the available water stored between cut-out and cut-in pressure. For example, a 10 gallon per minute pump usually needs at least 10 gallons of drawdown for a one minute run time. That often means an 80 to 119 gallon tank rather than the 20 gallon unit that came with the home. Upsizing is one of the best ways to extend pump life.
Preventative Well Pressure Tank Maintenance in St. Charles, MO
While our primary service is well pressure tank replacement, FGV Plumbing also stresses the importance of preventative maintenance for your well system in St. Charles, MO. Regular checks of your pressure tank's air charge and overall condition can help identify potential issues before they lead to a complete failure. During a maintenance visit, we can top off the air charge, inspect for early signs of corrosion or leaks, and advise on steps to maximize the lifespan of your current tank, potentially delaying the need for replacement.
Bladder-Style Pressure Tank Replacement in St. Charles, MO
Most modern well pressure tanks are bladder-style, separating air and water for better efficiency. When the bladder fails, you'll experience symptoms like short-cycling of the well pump. FGV Plumbing carefully replaces these bladder-style tanks across St. Charles, MO, ensuring proper pre-charge pressure and system integration for long-lasting performance.
Constant Pressure System Conversion in St. Charles, MO
A constant pressure system pairs a variable speed drive like the Franklin SubDrive or Grundfos SQE with a smaller pressure tank. The pump speeds up or slows down to hold a set pressure, so showers do not fade when a sprinkler kicks on. These systems cost more, often $2,500 to $5,000, but they end pressure swings. They also cut down on hard starts on the motor. We explain whether your well and pump are good candidates.
Bladder Pressure Tank Replacement in St. Charles
Bladder tanks hold water inside a flexible butyl bag surrounded by pressurized air. When the bag ruptures, water fills the whole tank, there is no air cushion and the pump short cycles. A quick test is pressing the air valve on top, since water spitting out means the bladder has failed. We replace the tank, set the new pre-charge and verify the pump runs a full cycle. Most bladder tank swaps take about two to three hours.

Diaphragm Pressure Tank Replacement in St. Charles, MO
Diaphragm tanks like the Amtrol Well-X-Trol use a fixed membrane that separates air above from water below. They are tough, but the steel shell can rust through at the base after years of condensation in a hot, damp equipment space. We replace corroded diaphragm tanks and check the stand and fittings under them. The new tank is leveled and supported so it does not stress the piping. This restores steady pressure to every faucet.

Frequently Asked Questions About Well Pressure Tank Replacement in St. Charles
Most well pressure tank replacements cost $900 to $2,200 installed, depending on tank size and whether the switch and tank tee are replaced. Large capacity or multi-tank setups can run $2,500 or more. We give a written price before starting.
We install a variety of trusted well pressure tank brands, including Well-Rite, Flex-Lite, Amtrol, and Goulds. Our technicians can suggest the best brand and model for your specific well system and budget.
While it might seem like a DIY project, well pressure tank replacement involves working with pressurized water, electrical components, and ensuring proper sizing and calibration. It is strongly recommended to hire a professional plumber to ensure safety, code compliance, and proper system function.
Yes, absolutely. A failing well pressure tank often causes the well pump to short-cycle, meaning it turns on and off too often. This constant starting and stopping puts heavy strain on the pump's motor, leading to premature wear and potential failure of the well pump itself.
A like-for-like tank replacement usually does not require a permit in most counties. Electrical changes or new piping may, and we check local rules for you.
Both bladder and diaphragm tanks use an air cushion to pressurize water, but they differ in how the water and air are separated. Bladder tanks have a replaceable rubber bladder that holds the water, fully isolating it from the air. Diaphragm tanks use a fixed rubber diaphragm. Bladder tanks are often preferred for their longevity and ease of maintenance.
FGV Plumbing offers a solid warranty on both the well pressure tank itself (as per manufacturer's warranty) and our installation labor. We stand behind our work to ensure your full satisfaction and peace of mind.
On average, a well pressure tank can last between 5 to 10 years, though some high-quality tanks can last longer. Factors like water quality, proper initial installation, and regular maintenance can significantly impact its lifespan.
