How to Get Air Out of Water Lines

Air trapped in your water lines can cause annoying sputtering faucets, uneven water pressure, and even damage to your plumbing system. If you’ve noticed any of these signs, it’s essential to address the issue before it worsens. Below, we’ll explore the signs of air in water pipes, the possible causes, and how to remove the air to restore proper water flow.

Signs of Air in Water Lines

Air in your water lines often makes itself known with a few telltale signs:

• Sputtering faucets: When you turn on the tap, and the water sprays unevenly or “spits,” air could be present in the pipes.
• Irregular water pressure: If the water pressure fluctuates between weak and strong bursts, trapped air could be the culprit.
• Noisy pipes: Hearing gurgling or banging noises from your pipes could indicate that air is trapped in the system.
• Cloudy water: Small air bubbles can cause water to appear cloudy when you first turn on a faucet.

Causes of Air in Water Lines

There are several reasons air might enter your water lines:

• Recent plumbing repairs: If you’ve had work done on your plumbing, air could have been introduced into the system.
• Water supply interruptions: A temporary shut-off from your water supplier can allow air to enter the pipes when the water is turned back on.
• Leaky pipes: A crack or gap in your plumbing can let in air as water flows
• Water well system: For those using a well, air might enter the pipes through a malfunction in the system, such as issues with the pump or pressure tank.

How to Remove Air From Water Lines

Here’s a simple process you can try to get the air out of your water lines:

1. Turn off your main water supply valve. Locate your home’s main water valve and shut off the water supply to prevent more air from entering.
2. Open all faucets. Turn on all the hot and cold faucets in your home, starting with the one on the highest floor and working your way down to the lowest. Don’t forget to flush the toilets as well.
3. Run water for several minutes. Once all faucets are open, turn the main water supply back on. Allow the water to run for several minutes. This process should push out the trapped air.
4. Check for improvements. Turn off each faucet, starting with the lowest and working your way back up. Check to see if the sputtering has stopped and if water flow is back to normal.

When to Consult a Plumber

If you’ve followed these steps but still notice signs of air in your water lines, it may be time to consult a professional plumber. Persistent issues could indicate more severe problems, such as leaks in your system, or problems with your water heater or well pump. A professional can identify the root cause and provide a long-term solution.
