How to Remove Air from Water Pipes: Step-By-Step Guide

Plumbing is something a lot of us take for granted until something goes wrong! If you’ve started hearing strange sounds coming from your water pipes, it could indicate trapped air. These sounds vary from persistent rattling to prolonged vibrations from within your walls.

Beyond the new noises coming from your pipes, your faucets may also start exhibiting some unusual behavior. If your taps are spluttering or releasing water in an irregular stream, this can also indicate trapped air in your pipes.

Most of the time, trapped air won’t cause significant damage to your plumbing. However, the repetitive knocking sounds and spluttering water can quickly get frustrating.

How Does Air Get into Water Pipes?

There are many ways air may get into your pipes. More commonly, air can get in following the installation of new pipes or alteration to your plumbing. Work like this doesn’t even have to happen in your own home for it to affect your pipes. If your neighborhood has recently had plumbing work, that can also cause air bubbles to enter your household pipes.

Air bubbles may also form following repeated heating, as evaporated water cannot escape your pipes properly. Ordinarily, due to the constant flow of water through your pipes, air bubbles will rise to the top of your system. This can make them somewhat stubborn to remove, but it is a relatively simple process when you know what you are doing.

Why is it Important to Remove Air from Water Pipes?

Most of the time, the air within your water pipes will not cause significant damage to your plumbing. It is only air, after all. However, trapped air can cause irritating problems such as:

  • Excessive noise coming from your walls
  • Reduced water pressure, resulting in weaker flow (especially noticeable in showers)
  • Spluttering faucets or inconsistent output
  • Rusting and corrosion in extreme cases
  • And more!

It is impossible to say for certain how trapped air may affect your plumbing system specifically. That said, it is not something you want to live with. If you feel confident that you may be able to fix this issue yourself, you can follow our step-by-step guide below!

  1. Turn Off Your Main Water Supply

There should be a valve or switch somewhere in your home that allows you to turn off your water supply. You need to do this first otherwise anything you do afterward is pointless. They often look circular or star-shaped and are made from metal, similar to what you would see on a garden hose.

If you can’t locate your main water valve or it just will not budge when you attempt to turn it off, do not force it. You may cause more damage than you intend to, and that will only add to your problems. It may have calcified over time, which will require professional assistance.

  1. Twist All of Your Faucets So They Run Water

Next, turn on all of your taps to allow water to flow through every faucet in your home. Make sure that you don’t turn the pressure too high. You just need to make it so the water is free-flowing enough to escape, it doesn’t need to be a high-pressure operation.

It is not just your faucets that need attention either. Turn on your dishwasher, shower, and washing machine too. Essentially, anything that uses water needs to be turned on. You should complete this in order of water sources closest to the main valve, ending with the furthest source.

  1. Wait for All Faucets to Stop Running and Flush Toilets

Wait for all water sources to run dry. How long this takes depends entirely on how much water your house was holding prior to turning the main valve off. You should flush the toilets at this point too (every single one of them). Keep flushing until there is no water available.

  1. Turn the Main Water Supply Back On

Once all your water sources have run dry, it is time to turn your main water supply back on. Once the valve is twisted, water should begin to flow through your faucets again. You should keep the water flowing for ten to fifteen minutes. Only stop once a steady stream has been achieved.

You should also flush your toilets, run your washer, and dishwasher once again. At this point, you should not hear any noises coming from your pipes. The lack of noise and a steady stream from your faucets indicate that the trapped air has been effectively removed.

  1. Turn All Faucets Off Again in the Correct Order

Just as you turned all of your faucets on in a particular order, you must turn them off in the reverse order. Start with the faucet furthest from your water supply valve and work your way back. Once you have completed this final step, you should be done!

If the problem persists, you may need to contact a professional to take a look. Loud thumps or bangs followed by no further noise are most likely to indicate water hammer, not trapped air. This can be much more serious and will require an expert’s opinion.
