Abstract: A manifold (88) for use with a hand held pump spray device (10) allowing the spray head (12) to draw simultaneously from two separate reservoirs (16, 18) containing two different fluids such that the spray head (12) raises a mixture of the two fluids in a predetermined ratio. The manifold (88) includes at least one ball check valve arrangement (82, 116, 120) in the suction line (104) to the chemical concentrate reservoir (18), the ball check valve (116) being normally biased to a closed position. The check valve (116) prevents the pumping of the concentrate when the diluent reservoir (16) is spent and further prevents cross contamination between the two fluids in the two reservoirs (16, 18) due to syphoning.
