ABSTRACT:
A manifold for use with a hand held pump spray device allowing the spray head to draw simultaneously from two separate reservoirs containing two different fluids such that the spray heads raise a mixture of the two fluids in a predetermined ratio. The manifold includes at least one ball check valve arrangement in the suction line to the chemical concentrate reservoir, the ball check valve being normally biased to a closed position. The check valve presents the pumping of the concentrate when the diluent reservoir is spent and further prevents cross contamination between the fluids in the two reservoirs due to syphoning.
