What You Need to Know About Ever-Reliable Pressure Tanks

A pressure tank is an important aspect of good maintenance for homes and commercial spaces. By minimizing rapid cycling of the pump and sustaining water pressure throughout the system, pressurized well tanks increase the lifespan of your well. A correctly sized pressure tank will meet your household's water needs while also protecting your pump from short cycling.

Pressure tanks keep the water pressure in a given facility consistent and, more significantly, protects the well pump's life. Water is needed from your well every time a faucet is switched on, or when someone takes a bath, or even when one uses the flush. The pressure tank carries enough water to meet these demands. This prolongs the period between the pump turning on and the pump turns off. 

How does the pressure tank work?

The main purpose of a pressure tank is to induce pressurized air to your water system so the pumped water will run immediately and stop in the same manner when you turn the controls on and off. When water is pumped from the well into the pressure tank, the air in the tank is compressed until it reaches a predefined pressure, usually 40 to 60 pounds per square inch. When a faucet is turned on, air pressure in the tank pulls water through the pipes until it reaches the predetermined trigger pressure, which is normally 20 to 40 psi. This activates the water pump, which subsequently draws water into the house and tank. When the faucet is turned off, pressure increases until the faucet is turned back on. The drop is the amount of water delivered by the pressure tank between when the pump goes down and when it restarts. Thus, you can put it simply like this:

Step 1: Normal State of the Water System

This is when the water system is not in use. Thus, the faucet is turned off, the flush is not in use, and the water is not welled. In this state, there is a buildup of air pressure inside the pressure tank.

Step 2: Turning on the Faucet

Once a control such as a faucet or a flush is activated, your well will pump the water to the pipes. However, when we think about it, we will be needing a lot of water to crawl into vertical pipes going into the top floor of a facility. This is where the pressure tank helps. The pressure inside the tank drives the water into the pipes.

Step 3: Turning off the faucet

When the faucet is turned off, the water that was cut from pouring will draw back into the pipes. The pressure tank will then produce pressurized air once again to aid the next activity.
