ABSTRACT:
A faucet includes a valve body having inlet conduits and an outlet. There is a valve control element within the valve body to control flow from the inlet conduits to the outlet. A vacuum breaker hub is mounted on the valve body and forms a chamber with the exterior of the valve body. The valve body outlet opens into the chamber. There is a vacuum breaker system on the hub which includes a plurality of openings in the hub communicating with the chamber. There is a flexible valve element on the inside of the hub which normally closes the openings. There are ribs within the chamber, extending inwardly from the hub which ribs are on opposite sides of the vacuum breaker openings to preclude the flow of fluid from the valve body outlet to the area of the chamber about the flexible valve element.
