Will an airlock clear itself?

What causes air locks in 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. Also, cold water pipes have less pressure compared to hot water pipes; as a result, it’s mainly hot water pipes that are affected by air locks.

Can you get airlock in cold water pipes?
Air locks almost never happen in mains cold water pipes.

Inadequate flow from a hot water tap supplied by a combi boiler is also very unlikely to be caused by an air lock.
What are the symptoms of air in a water system?

What are the warning signs of water hammer?
The most evident warning sign of water hammer is the noise. It sounds like a loud, abrupt BANG or a THUG. It can often be accompanied by rattling in the piping. Typically, it happens more than once as the supersonic pressure wave bounces back and forth in the piping system.

Does air in pipes make noise?
Trapped air is one of the causes of noisy plumbing, ranging from a vibrating sound to repetitive jack-hammer noises. Once air gets trapped in the circuit, especially in higher pipes, apart from draining the system and reconnecting the water supply with open faucets, it can be difficult to eliminate.
What can cause water pipes to vibrate and make noise?
