Abstract
A dispenser suitable for dispensing multiple solutions to, preferably, multiple utilization points. A laundry washing system (18) according to the invention includes a dispenser (20) which dispenses a plurality of cleaning solution to a plurality of washing machines (72) through a single common conduit (25). Conduit (25) is flushed after dispensing one solution but before dispensing a second chemically incompatible solution. A preferred dispenser (20) is capable of servicing multiple laundry machines (72) using a first-in first-out approach wherein the machines request service from a control system (74) which temporarily disables any "late-comers" until the appropriate solution can be dispensed to the machine (72) making the first, or highest priority, request.
