The new Doc Tech, with exclusive Docol Presence® technology, allows you to turn on and off the water flow with just one touch on any metal part of the product. This means new benefits such as saving time and freedom in kitchen tasks. Simply adjust the single-lever lever once to set the water flow and temperature. The piece also has a blue LED at the base of the vertical cylinder that indicates that the system is activated. The lever can be used to set the water flow and temperature preferences. This function eliminates the need to manipulate these parameters each time you use them, making kitchen tasks more practical, comfortable and hygienic.
