An airlock in pipes will either prevent hot water from leaving the taps or leave your radiators cold. Airlocks happen when air gets trapped in the hot water or central heating system. This then prevents hot water from circulating properly. Airlocks happen when air is trapped in the system. This air forms a blockage which gets in the way of the hot water as it makes its way to the taps or the central heating system. An airlock in the hot water system will prevent water from coming out of the affected tap.

While an airlock in the central heating system will result in some, or all, of your radiators failing to heat up properly. There are 2 ways to remove air from the hot water system and we talk you through them both below. The first way to clear an airlock, involves attaching a hose pipe to the hot and cold taps at a sink. Then, turn the cold tap on so that the water flows through the hose pipe and into the hot water tap.

This flow of cold water into the hot water tap should clear the airlock. Step 1: At 1 of the sinks in your home, use the hose pipe and duct tape to connect the hot water tap outlet with the outlet of the cold water tap. If not, then you might want to try the second method. Step 2: Turn on all taps, beginning with the top floor and then working your way downstairs, and wait until the water stops flowing. Following these steps should force any trapped air out of the system, allowing the hot water to flow again.
