WC bowl servicer jets pre-mixed foamed service water onto top of bowl water having thickwalled foam bubbles to conserve foam effect for up to one minute.
A layer of foam (SCHAUM) on top of the bowl water (WASSER) has bubbles of 10-20 mm diameter whose thicker walls preserve the foam for one minute at most, with a foam layer standing 20-200 mm in height. The foamer is connected to the service water line connection (BRAUCHWASSERANSCHLUSS), using a valve (SCHALTVENTIL) to direct the water through a mixer valve (MISCHVENTIL) where added foamer (SCHAUMMITTEL) from its container (SCHAUMBEHALTNIS) leads the mixture through a mixing sector (MISCHSTRECKE) whence foam is ejected via nozzle (SCHAUMD
