When we wash vegetable or dish, the water can not be controled by ourselves because the faucet is fixed. Don't worry, I have found a kind of faucet which can be changed the length of tub and the direction of the water by your needs. It is Pull-down faucet.
Pull-down faucet gives homeowners the convenience of a faucet and a spray nozzle without having to drill extra holes. Its toggle control makes it easy to change from stream to spray. The pull-down hose reaches 24 inches and swivels 360 degrees. It also has a water-saving flow rate of 2.2 gallons per minute.
