David for Model Number 79641172211 Does the float assy. AP4436884 act as a backflow preventer? If not is there a backflow preventer in this model?
Answer David, No, the 4769ER4001B Float assembly is not a backflow device. The float was originally designed to control the suds that may develop in the tub and escape through the vent system. It has since been eliminated by the manufacturer. The dispenser assembly basically serves as a backflow preventer.
