Pressure tanks

What is a pressure tank

The biggest function of the pressure tank is to regulate the stops/starts of the well pump, which allows it to have a longer life.


The reservoir is one of the core parts of the well pump system. It is so important that often when a tank fails the system breaks down and sometimes the pump has to be replaced due to too much starting demand.  

The air contained  in the tank  exerts a  pressure on the diaphragm and the water with power towards the piping of the residence.

What is the difference between a bladder tank and a diaphragm tank?

Balloon tank (bladder)

They are made to last 5 to 10 years in most brands such as Well-mate or Burcam Flotec etc.

The result of using a balloon is that the reservoir lasts less and encourages the proliferation of bacteria in the balloon since it never empties completely. Balloon tanks also lose more air pressure than other models and require much more maintenance (6 months). The balloon tends to stretch and split causing the system to fail. They are often considered ‘entry level’ generally and less expensive.

Diaphragm tanks

On the other hand, diaphragm tanks are much more solid, their construction allows them to empty completely which gives more drinkable water and they lose much less air and require almost no maintenance (1 year). They are made to last 15 years in most brands such as Well-X-Trol or Well-Rite. We install and recommend this type of tank.

When to replace a pressure tank?

Due to its importance, the replacement of the tank should be done to prevent its breakage in its 15th year. It is always better to have a tank in good condition, it prevents more expensive pump breakage.

If your tank is heavy with water when you move it, it is faulty. It needs to be replaced.

If your tank has rust like the examples here, it’s time to replace it to prevent water damage.

How do I know if my tank is defective?

Here are 6 quick ways to see if your tank needs replacing

  1. There is water coming out of the air valve.
  2. When the pressure in the house is at zero the tank is heavy and you can hear water inside when you move it.
  3. The pump often starts as soon as you take in water it starts and stops just as quickly (the normal cycle should last between 30 sec. and 60 min., the longer the better)
  4. The water is dirty when the pump starts.
  5. There is zero psi in the reservoir and it is full, due to full stretching of the balloon, we recommend replacement.
  6. The tank leaks, presence of rust, cracks or apparent defect.

Best pressure tanks

Two brands come to mind (Well-Rite product from Flexcon) or (Well-X-Trol product Amtrol).
Which one to choose? the answer is simple, with either you’ve been in business for a minimum of 15 years.

How long can a pressure tank replacement take?

The real answer is: it may vary from installation to installation, an average of 1.5 hours is realistic.

Should I hire a professional for tank installation?

The answer is yes because we will do the calibration well and we manage the warranty returns for a minimum of 5 to 7 years, you will have peace of mind.

Does my faulty tank affect the life of my well pump?

YES, however it is difficult to say how much time the pump has lost in its life, we can still make sure it is working properly.


It is recommended to calibrate and check the tank at least once a year. To learn more about maintaining your pumping system, please see our Tank Calibration page.

Visually inspect the tank and its connection to the system piping for any signs of water leaks or corrosion on outside the tank or connection.

Troubleshooting Tips

How to identify a lack of pressure

When we talk about a lack of pressure, we must identify whether the lack is ”constant” or ”intermittent”. =>A constant lack of pressure: in most cases affects the entire house and we do not see an increase in pressure. Example:
