Save up to 70% of your water consumption with this ingenious automatic, touch-free Auto Spout. Easy to install, it simply attaches on to your existing tap. The infrared sensors mean that there is no need to turn taps on and off; when you want to wash your hands just move them under the Auto Spout and this will activate the water-flow, making it not only convenient but also a hygienic alternative to a conventional tap. Comes with full instructions. It requires 4 x AAA batteries which are not included. This is suitable for most modern taps but will not work with pull-out faucets, showerheads, or taps that have a square outlet.
