Preventative Well Pressure Tank Maintenance in Lewistown, MT
While our primary service is well pressure tank replacement, DFV Plumbing also emphasizes the importance of preventative maintenance for your well system in Lewistown, MT. 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.
Constant Pressure System Conversion in Lewistown, MT
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-Style Pressure Tank Replacement in Lewistown, MT
Most modern well pressure tanks are bladder-style, separating air and water for optimal efficiency. When the bladder fails, you'll experience symptoms like short-cycling of the well pump. DFV Plumbing carefully replaces these bladder-style tanks across Lewistown, MT, ensuring proper pre-charge pressure and system integration for long-lasting performance.
Well-Rite Pressure Tank Installation in Lewistown, MT
Well-Rite pressure tanks are a common choice known for their reliability and durable construction, featuring heavy-duty steel shells and high-quality butyl diaphragms. At DFV Plumbing, we frequently install Well-Rite tanks as part of our well pressure tank replacement services in Lewistown. These tanks are designed to provide consistent water pressure and reduce pump cycling, extending the life of your well pump. We ensure proper sizing and installation of Well-Rite tanks, adhering to manufacturer specifications for full performance and warranty validity.
Pressure Tank Sizing and Upsizing in Lewistown
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 usable 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.

Bladder Pressure Tank Replacement in Lewistown
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 simple 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 confirm the pump runs a full cycle. Most bladder tank swaps take about two to three hours.

Frequently Asked Questions About Well Pressure Tank Replacement in Lewistown
The cost for well pressure tank replacement in Lewistown, MT usually ranges from $800 to $2,000. This depends on the tank size, brand, system complexity, and any additional components like pressure switches or gauges that might need replacing. We provide a detailed, upfront quote after a complete on-site assessment.
Regular maintenance for a well pressure tank involves checking the air pressure in the tank at least once a year, ensuring it's properly pre-charged. You should also listen for frequent pump cycling and visually inspect the tank for any signs of corrosion or leaks. We can include this check during regular well system servicing.
A new well pressure tank mainly helps maintain consistent water pressure and reduces pump cycling. If your current low pressure is due to a failing or undersized tank, a replacement will definitely improve the consistency and feel of your water flow. However, if the issue is with the well pump itself or a clogged pipe, other solutions might be needed.
A typical well pressure tank replacement generally takes between 2 to 4 hours. This includes disconnecting the old tank, installing the new one, and testing the system to ensure proper operation and correct pressure.
It depends on your pump's flow rate and the drawdown needed for at least a one minute run time. We calculate this on site instead of guessing from the old tank.
DFV 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.
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.
Some handy homeowners do, but mistakes with tank sizing, pre-charge and switch wiring are frequent. A wrong setting can cause the same short cycling that ruins the pump.
