How to Get Air Out of a Water Line

Remove Air Blockages From Home Water Lines and Pipes

• 1). Locate the shut-off valve for your home's water lines. Once you have found the shut-off valve, turn off the water flow to your house.
  
  
• 2). Open all faucets in your home. Every shower, bath and sink faucet should be open. Water may drain from the faucets for a moment until the lines have emptied.
  
  
• 3). Allow a adequate amount of time---about five to 10 minutes---for the air bubble to dissipate.
  
  
• 4). Turn the water valve back on to return water flow to your line system.
  
  
• 5). Shut off the faucets in your home to finish the process.
  
  

Removing Air Blockage From Single Faucet

• 1). Slide one end of the garden hose to the affected faucet, and the other to a faucet that is functioning properly.
  
  
• 2). Open both of the sink faucets. The pressure of the water coming from the working faucet will force the air out of the pipe.
  
  
• 3). Let the faucet run for one to two minutes to ensure removal of the air bubble.
  
  
• 4). Shut off the faucets, starting with the faucet with the blockage. Wait a few minutes, then shut off the working valve.
  
  
• 5). Remove the garden hose and test the clogged faucet. If there is still an air bubble, repeat the process.
