Pressure tanks help maintain consistent water pressure while reducing wear on well pumps and water systems. By storing pressurized water for everyday use, these tanks support smooth operation and reduced pump cycles throughout the home. Lowe’s offers pressure tank systems in multiple capacities, configurations and materials.


Benefits and Key Features of Pressure Tanks

  • Consistent Water Pressure: Pressure tanks help deliver a steady flow of water to faucets, showers and appliances throughout the home.
  • Reduced Pump Cycling: Pressure storage tanks help decrease how often a pump turns on and off, which can help extend pump life.
  • Improved System Efficiency: Storing pressurized water allows the system to respond quickly to household demand.
  • Residential and Commercial Use: Pressure tank systems are available in multiple capacity sizes to support different water usage requirements.
  • Flexible Installation Options: Vertical and horizontal pressure tanks can fit different installation spaces.
  • Thread-Size Selections: They’re available in multiple connection sizes to match existing plumbing and pump system requirements.
  • Material Choices: Steel, stainless steel and carbon steel pressure tanks offer durability options for different applications.
  • System Components: Tanks with pressure relief valves offer added system protection and performance.


How to Choose Pressure Tanks

  • Determine Tank Capacity: Match tank size to your household water demand and pump specifications.
  • Choose the Right Configuration: Select vertical or horizontal tanks based on your available installation space.
  • Verify Connection Requirements: Confirm thread-size compatibility before purchasing a replacement or new tank.
  • Consider Material Preferences: Compare steel, stainless steel and carbon steel options based on durability and operating conditions.
