Airlock in a water supply is primarily caused by trapped air within the pipes, which can block the flow of water, creating a vacuum. This can occur after maintenance work, a significant drain of the system, or when the supply is first turned on. To resolve an airlock, you can often use a method such as running the taps in your home for a few minutes to allow the trapped air to escape, or more effectively, by connecting a hose between a working tap and the affected tap, and running water through it to push the air back into the main supply.
