Maintaining the correct air pressure in your bladder tank is essential for the proper functioning of your well system. A well-maintained pressure tank ensures consistent water pressure, reduces pump cycles, and extends the life of your well pump. However, when the pressure in the tank is too high or too low, it can lead to problems such as low pressure, rapid cycling, or even a ruptured bladder.
For homeowners in New Milford, Litchfield County, and Upper Fairfield County, understanding how to maintain the correct air pressure is key to ensuring that your well pump operates smoothly. This guide will walk you through the process of checking, adjusting, and maintaining the ideal pressure for your tank, helping you avoid costly repairs and keep your water system functioning properly.
What Is a Bladder Tank and How Does It Work?
A bladder tank, also referred to as a pressure tank, is a crucial part of any well system. Its primary function is to maintain consistent water pressure throughout your home. Inside the tank is a bladder made of rubber that separates the water from the air. The pressure switch regulates the tank’s pressure settings, ensuring the system operates efficiently.
The air pressure in the tank pushes water into your pipes when the well pump is running. As water fills the tank, air in the tank gets compressed, which forces water into your plumbing system when needed. The cut-in pressure is the point at which the well pump kicks on to refill the tank, and the cut-off pressure is the point at which the pump turns off.
Correct pressure settings are vital for ensuring that your well system functions without interruptions, providing you with steady water flow throughout your home. If the well tank’s pressure is incorrect, your pump may cycle too often, leading to short cycling or other performance issues.
Why Is Air Pressure Important for a Bladder Tank?
The air pressure inside your bladder tank plays a significant role in the overall performance of your well system. Maintaining the correct air charge ensures that your system runs smoothly and efficiently, providing consistent water pressure and reducing wear and tear on your well pump. Here’s why proper tank pressure is crucial:
1. Consistent Water Pressure
The air pressure in the bladder tank ensures that your household pressure remains stable. If the pressure in the tank is too low, it may lead to fluctuating water pressure, resulting in weak flow or surges. Maintaining the right pressure setting helps ensure a steady water flow to your taps, showerheads, and appliances.
2. Pump Efficiency
When the tank pressure is set correctly, your well pump will turn on and off only when necessary, reducing the risk of rapid cycling. Frequent cycling due to improper air pressure can cause unnecessary strain on the pump motor, leading to premature pump failure. By maintaining the right air charge, you can ensure that your pump operates efficiently and lasts longer.
3. System Longevity
A well pressure tank with the correct air pressure reduces the wear on the entire system. If the pressure in the tank is not properly calibrated, it can result in waterlogged bladder pressure tanks, pump motor cycling, and even premature tank failure. Regularly checking and adjusting your tank’s pressure helps extend the lifespan of your well system.
How to Check and Adjust Your Bladder Tank’s Air Pressure
Checking and adjusting the air pressure in your bladder tank is a simple process that can save you from costly repairs. Follow these steps to ensure your pressure tank is properly calibrated:
Tools You’ll Need:
- Pressure gauge (or tire pressure gauge)
- Air compressor
- Wrench (for adjusting the air valve)
Step-by-Step Instructions:
- Turn off the power to the well pump: Before beginning, make sure the well pump is off to prevent any accidents while you’re adjusting the tank.
- Drain the tank: Open a faucet to drain the well tank completely. This will help you get an accurate reading of the air pressure.
- Check the air pressure: Locate the air valve (also called the Schrader valve) on top of the bladder tank. Attach the pressure gauge to the valve and check the air pressure. If you don’t have a dedicated air pressure gauge, you can use a tire gauge.
- Adjust the air pressure: If the air pressure is too low, use an air compressor to add air. The ideal pressure setting is usually 2 PSI below the cut-in pressure of your pressure switch. For example, if the pressure switch is set to 40/60 PSI, adjust the tank pressure to 38 PSI.
- Turn the power back on: Once you’ve adjusted the pressure in the tank, turn the well pump back on and check the system to make sure everything is functioning correctly.

Troubleshooting Common Bladder Tank Air Pressure Issues
If your well system is experiencing issues like inconsistent water pressure or short cycling, the pressure tank may be to blame. Here’s how to troubleshoot common air pressure issues:
1. Low Water Pressure
If you’re noticing low water pressure, it may be due to low air pressure in your bladder tank. Add air using an air compressor to restore the correct pressure in the tank.
2. Frequent Pump Cycling
If your well pump is turning on and off too frequently, it could be due to low tank pressure. This is known as short cycling and can put unnecessary strain on your well pump. Adjust the air charge to ensure the pump only cycles when necessary.
3. No Water Flow
If there’s no water coming from your faucets, it could be a sign of a ruptured bladder inside the tank, or there could be a major issue with the air pressure. In this case, you’ll need to inspect the pressure tank or call a professional for repairs.
4. Pump Running Continuously
If the pump is running non-stop, it could indicate that the pressure switch setting is incorrect or the air pressure is too high. Adjust the air pressure or call a technician to inspect the system.
How Often Should You Service Your Bladder Tank?
To ensure that your bladder tank continues to function properly, it’s important to have it serviced regularly. Here’s how often you should check the air pressure in your pressure tank:
1. Annually
It’s recommended to check the air pressure in your bladder tank once a year. Regular maintenance helps to catch any issues early and ensures that the system is running smoothly.
2. Before Selling Your Home
If you’re selling your home, having the pressure tank checked is a good idea. Potential buyers will appreciate knowing that the well system is properly maintained.
3. After Major Repairs
