The system consists of liquid soap dispensers (5, 6) located adjacent to wash basins (3, 4) in a washroom (1) and fed from a storage container (7) in a separate technical compartment (2) accessible to maintenance staff only. The liquid soap is fed through a closed circuit (8) with outward (8a) and return (8b) sections with pump (9) and gravity chamber (10) feeds, the latter operating when the pump is switched off.
