To fix an airlock, start by turning off the main water supply and then open the highest faucet (tap) in the house. Proceed to open the lowest faucet (possibly outside or in the basement) to let water back through the system, which often clears the airlock. If this doesn’t work, attach a hose to the problematic faucet and another working one, then open both to allow water to run through and dislodge the air. Remember to turn back on the water supply and check if the problem is resolved.
