When you are trying to remove air from your noisy water pipes, your main goal is to flush all of your water pipes well. The way to remove air noise from pipes is to speed up the moving water, which will push the air out of the faucets along with the rushing water. Noisy water pipes caused by air will sound like vibrating and rapid ticking. The sound can be loud and annoying. By increasing the water's velocity in the pipes for a short time, you can quiet those noisy pipes.
Turn on every faucet in the home. This includes the washing machine, outside spigot, and bathroom faucets.
Flush all toilets a few times, allowing the water to rush through those pipes as well.
Listen for water bubbles to pass through the faucets. This may sound like hissing or popping.
Run the water a few minutes more, allowing plenty of water to flush through the pipes once all sounds of air passing through has ceased.
Shut the water off at each faucet. Start at the lowest faucet, such as the washing machine or outside spigot. Continue shutting off each faucet one by one, working your way upward until all faucets have been turned off. Your noisy water pipes should now be much quieter, and you should only hear the sound of rushing water when the water is used.
