Why Air Gets Trapped in Water Pipes

There are several reasons why air can get into your pipes. Be it during repair, maintenance, or old plumbing, it is aggravating when it makes noise. You must know why air traps happen to avoid them in the future.

Repairs and Installations

Once the plumbing is completed, the air tends to get into the pipes. It may leak when water is switched off during repair. When the water is restored, the air trapped passes through the system, producing noise.

Old and Loose Plumbing

Ageing pipes or loose fittings have a greater likelihood of trapping air. Older pipes develop tiny cracks through which the air may get through. This is prevalent in houses having an antique plumbing system in London.

Fluctuating Water Pressure

The air can also be trapped in the system due to changes in the water pressure. When the pressure is extremely high or low, it will push the air into the pipes. This tends to create a greater noise when you switch on the taps.

Water Supply Interruptions

Wholesome interruption in the supply of water can lead to the influx of air in your pipes. A sudden switch of the water flow may cause air in the piping, whether it is the maintenance work in your neighborhood or an interim problem in the local water system.

How to Remove Air from Your Water Pipes

When your pipes are making a noise then it is probably caused by trapped air in the system. Fortunately, you can easily take the air out of your pipes and regain a steady and noiseless flow of water. The following is a step-by-step process of doing so.

Turn On All the Taps in Your Home

The initial process of clearing air in your pipes is by running all the taps. Start with the tap that is most distant from your water source, such as the one in the upstairs bathroom. Switch it to its full and leave it for a few minutes. This will assist in pushing the entrained air out of the system to allow the water to flow easily.

Flush Your Toilets to Help Release Air

Flushing your toilets may seem unrelated, but it can help release trapped air, especially in homes with complex pipework. Whenever you give it a flush, water is pushed down to the pipes, pushing out the air in the pipes. It is an easy trick, which may at times assist in clearing the system.

Bleed Your Radiators

If your home has radiators, trapped air can not only affect your plumbing but also the heating system. To empty your radiators, a radiator key is needed to unscrew the valve at the top of it, and slowly empty them. Allow the air to escape until water starts to flow continuously. This will assist in avoiding a noisy radiator and in making your heating system efficient.

Check for Leaks in the Plumbing

In the event that air is still trapped in the pipes despite the best of your efforts, there is a possibility of a hidden leak in the system. Inspect visible plumbing for any leaks or dampness, or water pooling. When you discover a leak, it should be repaired immediately so as to leave no more air to accumulate.

Call a Professional Plumber for a Thorough Inspection

In case the air does not clear or the noises continue to exist, it is time to refer to a professional plumber. The plumber will inspect your system properly, with the aid of special equipment, to bleed the pipes or to install air vents. Our team is here to help you through. We often arrive within a few hours and get everything back to order again.

Why You Should Remove Air from Your Pipes Quickly

While air in your water pipes might seem like a minor issue, ignoring it can lead to bigger problems down the road. That is why you should take care of the air in your plumbing as soon as possible.

Eliminate Low Water Pressure

Water pressure can be lowered by air in your pipes. Weak showers or low pressure may be experienced, and this is a result of blocked or uneven water flow. By removing the air promptly, you can restore steady pressure and avoid frustration.

Avoids Damage to Your Plumbing

When you leave air in your pipes too long, it may damage them. The air getting trapped may result in water hammer, giving your pipes a bang. With time, this may loosen the fittings of pipes or lead to leaks.

Prevents Damage to Your Plumbing

The noise is the most evident indicator of air in your pipes. Annoying sounds are gurgling, rattling, and knocking. The solution will help you have the quiet flow of water and make your home more peaceful.

Stops Unwanted Noises

If you have radiators, trapped air can affect your heating. Air pockets may prevent proper heat-up of radiators, and your home will not be as comfortable. Eliminating air makes your heating system run efficiently.

Keeps Your Heating System Working Properly

Leaving air in your pipes is something that should not be ignored, as it might cause larger plumbing problems in the future. Such minor issues as noisy pipes may become significant problems when not addressed promptly. It is much better to deal with it now than pay for expensive plumbing repairs in the future.
