Understanding Pressure Tanks

Pressure tanks play an essential role in well water systems, maintaining consistent water pressure and ensuring efficiency. There are various types of pressure tanks, each designed for specific functions. Learning how these tanks operate will help you make informed decisions regarding their maintenance and replacement.


Types of Pressure Tanks

There are mainly three types of pressure tanks available:

  1. Bladder Pressure Tank This consists of a rubber bladder that separates air from water. When water enters, it compresses the air, maintaining steady pressure.

  2. Diaphragm Tank Similar to the bladder tank, it uses a flexible diaphragm instead of a bladder. This design provides better water quality since the diaphragm prevents direct contact between water and the air.

  3. Air-Over-Water Tank Features no separating membrane. It allows air and water to coexist in the same space. However, this design can lead to water quality issues if not maintained properly.


Choosing the right tank depends on factors such as budget and maintenance requirements. At Excel Mechanical, we can assist you in selecting the best option tailored to your specific needs.


How Pressure Tanks Work

Pressure tanks operate on a simple principle. They store water and compress air to create pressure in your system.

  • Water enters the tank from the well pump, pushing against the air pocket.

  • Pressure builds up until it reaches the set limit, typically between 50 and 60 psi.

  • When you turn on a faucet, the compressed air forces the water out, delivering a consistent flow.


A pressure gauge attached to the system allows you to monitor the tank pressure. Regular maintenance is crucial to extend the tank's lifespan and optimize performance.

Installation and Maintenance

Proper installation and routine maintenance are crucial for ensuring the longevity and efficiency of your well pressure tank. Focusing on these aspects can prevent costly repairs and improve the overall performance of your water system.


Proper Installation Techniques

When installing a well pressure tank, it's vital to follow specific guidelines to ensure a successful setup. First, choose a location that provides easy access for maintenance and repairs. Ensure the area is clean and dry, as moisture can lead to corrosion.

Next, connect the tank to your well pump properly. Ensure all fittings are tight to prevent leaks. Adjust the pressure switch setting to achieve the desired cut-in and cut-off pressure. Typically, the cut-in pressure is set around 28 psi, while the cut-off pressure is often around 50-60 psi.


Finally, consider utilizing the services of professionals like Excel Mechanical. Our team is committed to delivering top-notch quality and tailored solutions for your HVAC and plumbing needs.


Routine Maintenance Procedures

Regular maintenance is essential for extending the life of your well pressure tank. You should frequently check the pressure switch for signs of wear. An unresponsive switch might require replacement, ensuring it can effectively control water flow.


Additionally, monitor the air pressure in the tank. The air pressure should be about 2 psi lower than the cut-in pressure. This can be checked by turning off the pump and draining the water from the tank.


Furthermore, inspect the tank for rust and corrosion. Address any issues quickly to prevent further damage. Scheduling periodic check-ups with Excel Mechanical helps maintain optimal performance, maximizing the value of your investment.


Common Issues and Troubleshooting

Addressing common issues with well pressure tanks is essential for maintaining optimal performance. Familiarizing yourself with potential problems and their troubleshooting steps can help ensure consistent water pressure and system reliability.
