Abstract: The present invention relates to a water-saver faucet to prevent wastage of water by allowing the user to pre-measure and use the desired quantity of water. The water saver faucet has a spout integral with faucet body. A knob is attached to a sliding shaft situated at the front end of the faucet body. A water pipeline is attached to other end of the faucet body. Seal assemblies are provided within the faucet body for sealing or releasing the flow of water. A graduated measuring vessel, attached to the faucet body, enables the user to directly pre-measure the quantity of water that will flow out of the water saver faucet. An air vent valve, provided on top of the graduated measuring vessel, facilitates the in/out flow of water through the graduated measuring vessel. An adopter facilitates the assembly of the graduated measuring vessel and the faucet body.
