A liquid soap dispensing system comprises a central liquid soap reservoir 12; a plurality of individual soap dispensers (4, Fig 1) arranged to dispense liquid soap to users; a plurality of individual soap reservoirs 7, these reservoirs feeding the dispensers with liquid soap; a liquid soap level detector (11f, 11l) in each individual reservoir 7; and a refill means for feeding liquid soap to a respective one of the individual reservoirs 7 from the central reservoir 12 in response to low liquid soap level detection at the respective individual reservoir. The dispensers may be manual pump action or automated with proximity sensors. Preferably, each individual reservoir has one Full level detector and one Low level detector (11f and 11l respectively). The refill feeding means may be a gravity feed system or a refill pump means. Preferably a control system is included to switch on the pump n response to low level liquid soap detection. |
