Clearing an airlock in a plumbing system requires a few straightforward steps. First, turn off the main water supply to reduce pressure. Open the faucet closest to the airlock, then gradually reopen the main water supply. This should force the air out through the faucet. If that doesn’t work, attach a hose to the problematic faucet and another working one, creating a direct connection. Turn both on, allowing water from the working faucet to push the air back and out of the system. Remember to proceed with caution and consider consulting a professional if you're unsure.
