A dispensing apparatus for dispensing a chemical product mixed with water is connected to a water supply through a line pressure diverter which relieves pressure in downstream of the water supply when the dispensing apparatus is not activated. Pressure is diverted by diverting the flow of water from a water supply to a second outlet port on the diverter. The line pressure diverter permits a dispensing apparatus to be installed on conventional water supply faucets without substantial modification thereto, and without causing damage to any pre-existing backflow prevention devices installed on the water supply.

[ What is claimed is:] [1.] A dispensing apparatus comprising:(a) a chemical product dispenser for dispensing a chemical product mixed with a diluent, the chemical product dispenser including a diluent inlet line for receiving a flow of diluent from a diluent supply, and a control valve for controlling the flow of diluent to the dispenser; and(b) a line pressure diverter, interposed between the diluent inlet line of the chemical product dispenser and the diluent supply, for diverting line pressure from the diluent supply when the control valve of the chemical product dispenser is closed, wherein the line pressure diverter includes:(1) an inlet, in fluid communication with the diluent supply;(2) a first outlet, in fluid communication with the inlet and the diluent inlet line of the chemical product dispenser; and(3) a second outlet, in fluid communication with the inlet through a pressure relief means for diverting diluent to the second outlet when pressure downstream of the diluent supply exceeds a predetermined level, wherein the pressure relief means includes a fulcrumed diverter member pivotally connected within the line pressure diverter to pivot between first and second positions, wherein when the control valve is not activated the diverter member pivots to the first position to place the inlet in fluid communication with the second outlet, and wherein when the control valve is activated the diverter member pivots to the second position to block the flow of diluent to the second outlet.
