Does anyone know how to detect water leakage in air conditioners? What are the main precautions?

Hello, the following is a summary for you. Who knows how to solve this problem? You can refer to it and hope it will help you. One: The most direct way is to change the door to the side. Two: between the gate and the toilet, set up partitions, such as screens and porches. Third, you can transform the door into a flat sliding door and draw some color pictures on the door. Four: Ordinary doors that cannot be transformed into sliding doors can also be painted on flat plates, making them a visual attraction. Five: Put some geomantic objects in the toilet, such as hanging a "Tiger Head Mahogany Eight Diagrams Mirror" or putting a string of "Five Emperors' Money, Six Emperors' Money/Ten Emperors' Money" on the floor mat.
