A water-saving device for a faucet includes a hose and a control assembly connected to the hose and adapted to be located upstream of the faucet. The control assembly includes a housing, a plunger, an operation unit connected to an end portion of the plunger, and a biasing unit disposed in the housing. The housing has inlet and outlet ports, a passage in fluid communication with the inlet and outlet ports, and a valve seat disposed in the passage. The plunger has a valve portion to be seated on the valve seat. The biasing unit moves the valve portion to a closing position in which the valve portion is seated against the valve seat, and the operation unit moves the valve portion to an open position in which the valve portion is moved away from the valve seat.
