Air Trapped In Hot Water Pipes

Airlocks happen when there s trapped air in the hot water or central heating system preventing the hot water from circulating properly.

Air trapped in hot water pipes. The main cause of an air lock in pipes is when pockets of air are trapped by the flowing water preventing the free flow of water. Air in hot water pipes only when the issue appears to be coming from the hot water pipes only it s an indication that you have air in your water heater. Don t forget the shower baths the washing machine and the dishwasher in the kitchen. In this guide we ll take you through the steps to clear the air from the system so that the water can flow normally again.

This is especially true of well fed systems and the trapped air will often replenish over a couple hours. After you turn on all the cold and hot water faucets in your house you should also flush your toilets to clear out the air trapped in your pipes. After a short time the water should begin to run smoothly from all the faucets. Turn on all the hot and cold water taps.

Also cold water pipes have less pressure compared to the hot water pipes. Let the water from all faucets and appliances run for 10 15 minutes until you no longer hear sputtering and spitting from your faucets. The idea is to get all water in your house to freely flow so turn on your washing machine and let it run through a rinse cycle and make sure that you remember to turn on your dishwasher as well. Air trapped inside infeed water pipes is common.

Don t be alarmed as the gurgling is normal given what you ve just done to the system. An airlock in the pipes will either prevent hot water from leaving the taps or leave your radiators cold. Sputtering faucets irregular water flow and vibrating pipes may indicate that you have air in your water lines. Air usually gets trapped at high points in your water supply system and to force.

Homeowners with heating systems that rely on boilers to warm water in radiators also encounter trapped air. This lack of spurting is the tell tale sign that your water system is now free of air bubbles. When air collects in parts of the pipeline without moving the water may be blocked by the air so that no water flows or it may circulate past the pockets of air by flowing underneath these pockets. Air in the pipelines air may be found in water pipelines mainly as large stationary pockets or as large or small moving bubbles.

The water will begin to run through them gurgling out at first. The pressure in the hot water pipes doesn t force the blockage out. You can now turn off all the remaining faucets in the house. As a result it s mainly hot water pipes that are affected by air locks.

The water will flow out for a very short while.
