Another method for fixing an airlock in kitchen sinks is to blast it out with two taps at once. First, undo the pipe on the faucet with the highest water pressure. This will prevent water from rushing out the bottom. Repeat the process until you have an airlock-free kitchen sink. If you're unable to remove the airlock in the sink, you may want to consider a new installation or a plumbing job.

Regardless of where your kitchen sink is located, it may be necessary to call a plumber if you can't find a simple way to fix the problem yourself. You can also try to locate the AAV by inspecting your sink's water pressure and temperature. The airlock can be caused by a buildup of debris or dirt. Once you know the cause, you can determine how to fix an airlock and avoid wasting more money on a plumber.
