Will an airlock clear itself?
An airlock will not clear itself. It acts like a restriction in the pipes and the only way to clear it is by blasting water at high pressure through it. Water pipes are hardly ever straight and that is why an airlock will not clear on its own, as it occupies the highest point of the pipes.
Can airlock cause no hot water?
What happens when you get an airlock in a pipe? If air gets trapped in your central heating or hot water system, this can stop hot water from circulating, causing radiators to stop heating up and hot water taps to stop running.
What causes an air lock?
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.
Why does my hot water keep getting air locked?
Causes of an Air Lock
Air lock occurs in plumbing systems when pockets of air in a pipe trap the water in the pipe, not allowing the water to flow freely through the pipe. This problem usually occurs in hot water pipes, since the water pressure from the hot water tank won’t force the air blockage out of the way.
