What To Consider When Buy The Well Pressure Tank?

Choosing the right well pressure tank is crucial for maintaining consistent water pressure in your home. This tank acts as a buffer zone, storing pressurized water delivered by your well pump and preventing it from short-cycling (rapid on-and-off cycles) that can damage the pump and lead to pressure fluctuations. With a well-sized and appropriate tank, you’ll enjoy a steady flow of water for your household needs.

This comprehensive guide dives into the essential factors to consider when buying a well pressure tank, ensuring you make an informed decision for your unique well system.

Understanding Well Pressure Tank Functions

Before delving into specific features, let’s establish a foundational understanding of how a well pressure tank functions. A typical tank consists of a steel shell containing a bladder or diaphragm made of rubber or a similar flexible material. The bladder separates the tank into two chambers: an air chamber and a water chamber.

  • Air Chamber: The air chamber pre-charged with air at a specific pressure (typically 35 psi). This compressed air acts as a cushion, pushing water into the house when the pressure drops due to water usage.
  • Water Chamber: The well pump fills the water chamber with pressurized water. As water is used throughout the house, the air chamber pushes water from the tank, maintaining pressure in the system until the pump turns on to replenish the tank.

Key Considerations When Buying a Well Pressure Tank

Here are the critical aspects to evaluate when selecting a well pressure tank:

  1. Size: Undoubtedly the most crucial factor, selecting the appropriate size tank ensures it can store sufficient water to meet your household’s demands and prevent the pump from short-cycling.
  2. Material: Well pressure tanks are primarily constructed from two materials:
  3. Steel: The most common and cost-effective option. They are durable and long-lasting but susceptible to corrosion over time, especially if exposed to moisture. Opt for galvanized steel tanks for better corrosion resistance.
  4. Stainless Steel: A superior choice offering exceptional durability and corrosion resistance. While more expensive than steel tanks, they are ideal for areas with high moisture or for those seeking a long-term investment.
  5. Pre-charged Pressure: The air pressure in the tank when empty. This pressure should be slightly below the pump cut-in pressure (the pressure at which the pump turns on) to allow the tank to deliver water before the pump activates. Consult your well pump manual or a qualified well service professional for the recommended pre-charge pressure for your specific system.
  6. Location: Well pressure tanks can be installed indoors or outdoors. Indoor locations offer protection from the elements but require space and proper ventilation to prevent moisture build-up and potential corrosion. Outdoor installations necessitate a frost-proof enclosure to shield the tank from freezing temperatures that can damage the bladder.
  7. Warranty: A warranty provides peace of mind in case of unforeseen malfunctions. Choose a tank with a reputable manufacturer’s warranty that covers defects in materials and workmanship.

Additional Considerations

  • Automatic Tank Trol (ATT): An optional device that can improve pump efficiency and longevity. An ATT monitors pressure fluctuations and automatically adjusts the pump’s cut-in and cut-out pressures, reducing short-cycling and optimizing tank performance.
  • Water Quality: If your well water contains high levels of iron bacteria, sedimentation, or other contaminants, a pre-filter system may be necessary to protect the tank’s bladder and ensure clean water delivery.

FAQs

How long does a well pressure tank typically last?

With proper maintenance, a well pressure tank can last for 10-15 years.

How do I know if my well pressure tank is malfunctioning?

Signs of a failing tank include: frequent pump cycling, water pressure fluctuations, waterlogged tank (indicating a bladder failure), or air escaping from the tank

Can I replace the bladder in a well pressure tank?

In some cases, it may be possible to replace the bladder in a well pressure tank. However, this can be a complex process, and it’s often more cost-effective to replace the entire tank.

Who should install my well pressure tank?

While some homeowners with experience and plumbing knowledge may feel comfortable installing a well pressure tank themselves, it’s generally recommended to hire a licensed plumber or well service professional. They can ensure proper installation and avoid potential issues that could damage your well system.

How do I maintain my well pressure tank?

Regular maintenance is crucial for extending the lifespan of your well pressure tank. Here are some key maintenance tips:

Check the air pressure: Periodically check and adjust the air pressure in the tank to maintain the recommended pre-charge level. Consult your well pump manual or a professional for the specific pressure for your system.

Drain the tank: Drain the tank annually to remove any sediment that may accumulate and potentially damage the bladder. Follow the manufacturer’s instructions for proper drainage procedures.

Inspect the tank for leaks or damage: Visually inspect the tank for any leaks, cracks, or signs of corrosion. If you notice any damage, it’s best to replace the tank promptly.

What are some additional factors to consider when choosing a well pressure tank?

Here are some additional points to ponder:

Brand reputation: Opt for a well-established brand known for producing reliable and high-quality well pressure tanks.

Replacement parts availability: Ensure replacement parts, such as bladders or pressure gauges, are readily available for your chosen tank model. This will simplify future maintenance and repairs.

Cost vs. value: While cost is certainly a factor, prioritize a tank size and material that best suit your needs. A slightly higher initial investment in a larger or stainless steel tank can translate to long-term savings and peace of mind.

Conclusion

Selecting the right well pressure tank is an essential decision for ensuring a smooth and consistent water flow in your home. By considering the factors outlined in this guide, you can make an informed choice that meets your specific well system requirements. Remember, consulting with a qualified well service professional can provide valuable advice and ensure optimal performance from your well system.
