The system works through a "flap" obtained with a particularly worked emission hole. During the irrigation cycle, the door rises and guarantees a regular water output, at the end of the irrigation cycle, the door returns to the rest position, closing the emission hole and, as a result, blocking any sludge and dirt infiltrations.
