If you’re finding air in well water lines, you’re not alone. In fact, this is a pretty common problem well users face every day. Although it may not seem like a big deal, you should still be concerned about it and get rid of it.
In this article, we’re going to explain the causes of air in well water lines and how you can get rid of it.
Let’s get started.
What Causes Air in Well Water Lines?

First of all, let’s look at what causes air in well water lines.
Well water is naturally under pressure. When the pump pulls water from the well, the water’s natural weight pushes it up through the pump and the pipes. This pressure is called “head pressure.”
Head pressure is essential because it ensures that water flows through the pipes and into your home.
Now, when you’re drawing water from your well, the water level in the well drops. This, in turn, decreases the water’s head pressure.
As the head pressure decreases, the air is drawn into the well. This air is naturally present in the water.
Some of the air that’s drawn into the well is pushed out of the well and up through the pipes. This causes your water to be “air-filled.”

Other Causes of Air in Well Water Lines
There are other causes of air in well water lines.
Airlock
One of the most common causes is an airlock. An airlock is caused when air gets trapped in the pipes. This happens when the pipes are filled with water.
The airlock prevents water from flowing through the pipes. As a result, the water level in the well drops.
When the water level in the well drops, air is drawn into the well. This air is then pushed out of the well and up through the pipes.
Leak in the pipes
Another common cause of air in well water lines is a leak in the pipes. When there’s a leak in the pipes, water flows out of the pipes. This, in turn, decreases the water level in the well.
When the water level in the well drops, air is drawn into the well. This air is then pushed out of the well and up through the pipes.
Get Rid of Air in Well Water Lines
Now that we know what causes air in well water lines, let’s look at how to get rid of it.
The first thing you need to do is identify the source of the air.
Air is coming from an airlock
If the air is coming from an airlock, you can simply purge the air from the pipes. To do this, turn on a faucet and let the water run until the air is purged from the system.
Air is coming from a leak in the pipes
If the air is coming from a leak in the pipes, you’ll need to repair the leak. Once the leak is repaired, the water level in the well will increase. This, in turn, will increase the water’s head pressure.
As the head pressure increases, the water will push the air out of the system.
If you can’t identify the source of the air, you can simply wait for the water level in the well to increase. As the water level in the well increases, the water’s head pressure will increase.
As the head pressure increases, the water will push the air out of the system.
Conclusion
Air in well water lines is a common problem well users face every day. Although it may not seem like a big deal, you should still be concerned about it and get rid of it.
