Have you ever wondered how that refreshing flow of water makes its way from deep within the earth to your tap? It’s all thanks to the intricate web of well water systems that bring this essential resource to your home. At the heart of this system lies the often-overlooked hero: the water well pressure tank. 

This unassuming piece of equipment plays a crucial role in maintaining steady water pressure, reducing pump cycling, and ensuring a reliable water supply to your household. In this article, we’ll take a closer look at the art of installing a pressure tank for your well water, guiding you through the process step by step. 

So, whether you’re seeking to upgrade your well system or embarking on a new installation, buckle up as we plunge into the world of well pressure tank installation.

Installing a Water Well Pressure Tank

Well pressure tanks, also known as well water tanks or pressure storage tanks, are a crucial component of well water systems. They help maintain water pressure and reduce the need for the well pump to cycle frequently. 

Here’s a rundown of the installation process:


  • Well pressure tank
  • Pressure switch
  • Pressure gauge
  • Tee fittings and pipes
  • Pipe wrenches
  • Teflon tape or pipe thread sealant
  • Pipe cutter or hacksaw
  • Pipe fittings (elbows, unions, and pipe nipples)
  • Wrenches and pliers
  • Pipe supports and hangers
  • Electrical wiring and connectors (if needed)


  1. Choose location: Select a suitable location for the pressure tank. It should be indoors or in a weatherproof enclosure to protect it from the elements. The location should also allow easy access for maintenance.
  2. Shut off power and water: Turn off the power to the well pump and shut off the water supply from the well.
  3. Install tee fitting: Install a tee fitting into the main water line after the well pump. This tee fitting will accommodate the pressure tank, pressure switch, and pressure gauge.
  4. Mount the pressure tank: Mount the pressure tank on a stable surface using appropriate brackets. Ensure the tank is level and adequately supported.
  5. Connect pipes and fittings: Attach pipes and fittings to connect the tee fitting to the pressure tank’s inlet and outlet ports. Use pipe wrenches to tighten the connections. Apply Teflon tape or pipe thread sealant to the threads of the fittings to prevent leaks.
  6. Install pressure switch and gauge: Attach the pressure switch to the tee fitting using appropriate fittings. The pressure switch controls when the well pump turns on and off based on water pressure. Install the pressure gauge on the tee fitting to monitor the system’s water pressure.
  7. Electrical connections: If the pressure switch requires electrical connections, follow the manufacturer’s instructions to wire it to the pump control box.
  8. Pressure tank precharge: Before turning on the well pump, set the pressure in the tank to the desired precharge pressure. This is typically a few psi below the pressure switch’s “cut-in” pressure.
  9. Turn on power and water: Turn on the power to the well pump and open the water supply valve from the well.
  10. Check for leaks: Carefully inspect all connections for any signs of leaks. If you notice any leaks, turn off the pump and address the issue before proceeding.
  11. Adjust pressure settings: Adjust the pressure switch settings if needed to ensure the pump cycles on and off at appropriate pressure levels.
  12. Testing: Open faucets and fixtures to let water flow and observe the pressure tank’s performance. The tank should fill and pressurize as needed, and the pump should turn on and off as the pressure changes.
  13. Final checks: Double-check all connections, ensure there are no leaks, and confirm that the system is functioning correctly.

Remember, well pressure tank installation may vary depending on the specific manufacturer’s instructions and the design of your well water system. If you’re not familiar with plumbing and electrical work, seek the assistance of a professional plumber or well system technician to ensure proper and safe installation.

Replacing a Well Water Pressure Tank 

A well water pressure tank may require replacement due to factors such as age-related wear and deterioration, ruptured bladder, internal corrosion leading to leaks, or diminished performance in maintaining consistent water pressure. 

Over time, accumulated sediment and mineral buildup can affect the tank’s functionality, causing it to lose its ability to store and deliver water effectively.

Replacing a well water pressure tank becomes necessary when these issues compromise the system’s efficiency, potentially leading to reduced water pressure, frequent short cycling, a waterlogged tank, and overall decreased performance of the well water system.

The process for replacing a well pressure tank is quite similar to the installation process, albeit with some variations. Here’s how you would go about replacing a well pressure tank:

  1. Prepare and gather tools: Collect the necessary tools and materials, including the new water pressure tank, pressure switch, pressure gauge, pipes, fittings, wrenches, Teflon tape or pipe thread sealant, and any other items you’ll need.
  2. Turn off power and water: Shut off the power to the well pump and turn off the water supply from the well.
  3. Drain the system: Open faucets to drain any water from the plumbing system and relieve pressure.
  4. Disconnect old tank: Disconnect the pipes and fittings from the old pressure tank. Use wrenches to loosen and remove any connections.
  5. Remove old tank: Carefully remove the old pressure tank from its mounting brackets or supports.
  6. Install the new tank according to the instructions in the previous section.

Well Pressure Tank PSI Settings

The PSI (pounds per square inch) of a well pressure tank directly impacts the performance of your well water system. The PSI essentially represents the pressure at which water is stored within the tank.

A well pressure tank typically has two important pressure settings: the “cut-in” pressure and the “cut-out” pressure. The cut-in pressure is the minimum pressure at which the well pump should start, while the cut-out pressure is the maximum pressure at which the pump should stop.

Setting the right pressure settings for your pressure tank is essential for optimal functioning. The cut-in pressure is usually set a few PSI below the desired water pressure for your household. This ensures the pump starts when the pressure drops slightly, replenishing the tank and maintaining consistent water pressure. 

The cut-out pressure is set to a point where the pump stops once the tank reaches its maximum pressure capacity. Finding the right balance between these two settings is crucial to preventing excessive cycling of the pump, which can lead to wear and higher energy consumption.

The specific pressure settings depend on factors such as your household’s water demand, the capacity of the entire tank, and the characteristics of your well pump. It’s recommended to consult the manufacturer’s guidelines for the pressure tank and the pump to determine the appropriate PSI settings. 

Additionally, monitoring and adjusting the pressure settings periodically, especially after a new installation or replacement, can help fine-tune the system for optimal performance and efficiency while ensuring a reliable and consistent water supply.


Regular maintenance of a well pressure tank is vital to keeping your well water system functioning smoothly. Just like any other piece of equipment, pressure tanks can face wear and tear. Regular checks help catch issues, like leaks, corrosion, or pressure imbalances, preventing them from turning into bigger problems that could disrupt your water supply. 

Checking the pressure settings also ensures that the tank and pump work harmoniously, reducing energy consumption and prolonging the lifespan of the system. 

By enlisting professional help, you’re not only safeguarding the health and efficiency of your well water system but also ensuring that the intricate components are handled with the care and precision they require, allowing you to enjoy a consistent and reliable water supply without unnecessary risks or disruptions.
