Abstract
A flow control assembly for a single lever faucet includes a coupler adapted to operatively connect a handle to a valve stem of a valve assembly. A cam mechanism has a valve stem portion and a handle portion, where the cam mechanism is operatively connected to the valve stem and the cam mechanism engages the valve stem to move the valve stem to a predefined open position in response to the handle being moved from a neutral handle position to a water on position. The coupler provides a biasing resistance that increases resistance to handle movement as the handle is oriented in a position other than a neutral handle position.
