A post-mix beverage dispensing system has a structure for flushing the dispensing valve and its nozzle of syrup using diluent water from the water supply; the dispensing valve has a nozzle, syrup and water valves and an actuator for the syrup and water valves, a mounting block for the dispensing valve has water and syrup ports with inlets and outlets and normally closed disconnect valves in the outlet enabling removal of the dispensing valve from the block, a flush connector goes across the bottom of the block and is fluidly connected into the water and syrup ports, a normally closed flush valve is in the connector and has an external pushbutton actuator for opening the valve for connecting the water port to the syrup port to flush the syrup port disconnect valve, flow control, syrup valve and nozzle with water, and there is structure to prevent flow of flush water into the syrup supply line. A method of flushing a post-mix valve has the steps of connecting the water line to the syrup line and flushing the syrup valve and nozzle with water from the beverage water supply. An alternative flush valve has structure for neutralizing the syrup pressure so that syrup pressure cannot open the flush valve if and when water pressure drops, and a lever type flush actuator behind the dispensing actuator lever enables easy flushing by squeezing the two levers together with the thumb and finger of one hand.

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. A method of flushing a post-mix beverage dispensing system comprising the steps of: (a) concurrently opening a syrup valve and water valve in a syrup line and water line respectively, both lines leading to a dispensing nozzle; (b) connecting the water line to the syrup line at a connecting point upstream of the syrup valve; (c) operating a discrete flush lever underneath the dispensing valve to connect the water and syrup lines by squeezing the flush lever and a dispensing lever together with the thumb and a finger of one hand, to connect the water and syrup lines; (d) precluding reverse flow of syrup in the syrup line; (e) propelling all syrup from the connection point to the nozzle out of the nozzle with a flow of flushing water from the water line via the connection point; (f) flushing the syrup valve and nozzle with a further flow of the flushing water; and (g) then disconnecting the water line from the syrup line so that syrup can again be supplied to the nozzle, which has just been flushed and cleaned with water from the water supply line, by releasing the squeeze upon the flush and dispensing levers.
