Claim 18:
19. A method of producing ozone with an ozone production system, the method comprising:
providing a plurality of washing machines;
generating ozone, via an ozone generator, for supply to each one of the plurality of washing machines;
supplying ozone, from the ozone generator to each of the plurality of washing machines, via an ozone supply conduit;
locating a respective venturi, for each one of the plurality of washing machines, along a water supply conduit between a water source and an inlet into the respective washing machine, and connecting the ozone supply conduit to each respective venturi for supply of ozone thereto;
permitting water to flow through the respective venturi, from the water source into the respective washing machine, so that such water flow creates a negative pressure within the ozone supply conduit;
locating at least one sensor so as to detect the negative pressure within the ozone supply conduit; and
connecting the at least one sensor to a control box, coupled to the ozone generator, to control ozone production of the ozone generator depending upon the negative pressure detected within the ozone supply conduit by the at least one negative pressure sensor/switch.
