This device for determining whether screening constructions of buildings are waterproof belongs to the branch of civil engineering. This device can be used for testing various constructions (walls, windows and roofs) to see if they are waterproof. The device consists of perforated pipe for water spilling, both ends of which are connected to a water feeding outlet, which has a mounted meter, through flexible hoses and a connective element in the shape of the letter "Y". Additionally, the device has a regulated air ventilator, the airflow of which directs the water flow and gives wind pressure to both the water flow and the tested construction. |
