Claim One:
1. A method of flushing at least part of the syrup components in a post-mix carbonated beverage dispensing system with carbonated water comprising the steps of: a. concurrently opening a syrup dispensing valve and carbonated water valve in a pressurized syrup line and pressurized carbonated water line respectively, both lines leading through a respective discrete opened disconnect valve to a dispensing nozzle; b. selectively and intermittently connecting the carbonated water line to the syrup line at a connecting point upstream of the syrup disconnect valve by opening a normally closed flush valve; c. precluding reverse flow of syrup in the syrup line by checking against reverse syrup flow upstream of the connection point; d. propelling all syrup from the connection point to the nozzle out of the nozzle with a displacing flow of carbonated flushing water from the carbonated water line via the connection point; e. flushing the syrup disconnect valve, syrup dispensing valve, and the nozzle with a further flow of the carbonated flushing water; f. concurrently flushing a syrup flow control in the syrup line with the carbonated flush water; g. concurrently flushing a disconnect valve in the syrup line and between a valve body and mounting block, with the carbonated flush water; h. disconnecting the carbonated water line from the syrup line by closing the flush valve so that syrup can again be supplied to the nozzle, said nozzle, syrup dispensing valve, syrup flow control, and syrup disconnect valve having been completely flushed of syrup and cleaned with carbonated water from the carbonated water supply line; i. neutralizing syrup pressure upon the normally closed flush valve so that if and when syrup pressure exceeds the carbonated water pressure the syrup pressure cannot open the flush valve; and j. discretely operating a discrete and dedicated mechanical flush actuator on the dispensing valve, said flush actuator being mechanically connected to said flush valve for mechanical operation of said flush valve in response to manual and mechanical operation of the flush actuator.
