Si le niveau de l'eau de drainage (3) monte et un couvercle de prévention de lavage à contre-courant disposé sur une surface supérieure du commutateur (14) flottant bloque l'intérieur du tube de passage (12), coupant ainsi la section inférieure (1b) à partir de la section supérieure (1a), de l'air comprimé est introduit dans la section inférieure (1b) à partir d'une partie (7) de réservoir d'air comprimé. L'eau de drainage (3) est amenée à s'écouler de manière forcée à travers un tuyau de drainage (4) vers un tuyau de ramification d'eau de drainage horizontal (5) par l'intermédiaire de la pression d'air de l'air comprimé.
