If you depend on a well to supply your home with fresh water, you trust that it will work faithfully year-round. But its functionality is chiefly dependent on its pressure tank. If something were to go wrong with this vital component, then it could impact the water supply system at large. Here’s what you need to know about how well pumps use pressure tanks.

What Is the Role of the Pressure Tank?

Well water supply systems rely on several key parts to ensure successful delivery to your home. One of those is the water well pump, which is situated adjacent to the well casing. Its role is to transfer the water to the pressure tank so that it can ultimately reach your home. The tank, meanwhile, is designed to reserve enough water to supply your home consistently. That prevents the pump from running continuously, thereby helping it last longer.

The tank contains air, which becomes compressed when water is pumped inside. At this stage, the water must reach a certain preset pressure of pounds per square inch (psi), at which point the pump can turn off safely. Usually, that ranges between 40 and 60 psi. Whenever you need water inside your home, the pressure lowers. The water must reach another preset range, usually between 20 and 40 psi, at which point the pump starts again. At a bare minimum, the pressure in the tank needs to be just as high as the pressure that the appliance or fixture you’re using requires.

What Are Some Common Concerns?

When it works properly, the pressure tank contributes to a well-tuned water supply system. In addition to regulating the pressure, it protects the pump from premature failure. If you suspect that it’s not working properly, it’s important to act promptly. A common problem is an imbalance of water and air within the tank. When there is too much fluid and not enough air, pressure levels will fluctuate and force the pump to cycle frequently.

You can check this by turning off the breaker to the pump, then turning on a faucet in the home to drain the water from the tank. Check the air valve cap for signs of a leak. If there’s a leak, you may need a tank replacement. You can also check the pressure at this stage; if it needs to be adjusted, you can add or remove air until it reaches just 2 psi under what the system requires. If your normal setting is between 40 and 60 psi, it should read 38 psi when you’re done filling it up.
