Abstract
A proportioning system includes a cutoff valve, a three-way valve, a check valve and an eductor. The cutoff valve has a cutoff intake port and a cutoff discharge port. The cutoff valve is capable of receiving a carrier fluid from a carrier fluid source and selectively discharging the carrier fluid or inhibiting carrier fluid flow. The three-way valve is capable of receiving a first active fluid and a second active fluid and is capable of selectively discharging a selected one of the first active fluid and the second active fluid, or inhibiting flow from of both the first active fluid and the second active fluid. The eductor is capable of receiving an active fluid when the carrier fluid is passing through the eductor so as to mix the active fluid with the carrier fluid.
