An improved chemical dispenser includes a plurality of eductors for
drawing chemical into a diluent to produce an effluent, each eductor of
the plurality selectively discharging via a baffle tube into a single
common discharge tube. The effluent flow parameters are insufficient to
cause effluent from a selected eductor to flow into a chemical source
coupled to a non-selected eductor, and are insufficient to draw chemical
from a non-selected eductor into the effluent from a selected eductor.
