A good touch sensitive kitchen faucet will never turn on by itself. They can be used on any type of sinks including metal ones. In the dawn of touch sensitivity in faucets, they had a number of problems including turning on too often by accident. In modern faucets, these problems are eliminated. It is wise, however, not to rely on just any touch sensitive faucet out there. There are cheap faucets without even name or brand that offer you a bunch of advanced features. If you buy one of them, it′s a gamble. In my opinion, the safest way to go is finding a brand whose touch sensitive faucets have proved to be reliable. The information available online can help a lot. User ratings, comments and reviews can give you a better idea about the quality. Be aware though that even the best faucet won′t work as expected if installed on a metal sink with insufficient insulation. In this case, the sink itself can become a "continuation" of the faucet, and it will turn on just by touching the sink. The problem will be gone when the faucet is installed with a proper insulation.
Cartridge Faucet - this washerless faucet is identified by the narrow metal or plastic cartridge inside the faucet body; and it is available in both single and double handled cartridge designs. Cartridge faucets have a hollow cartridge insert that lifts and rotates to control the flow and temperature of water. Dripping at the spout occurs when the cartridge seals wear out. Leaks at the base are caused by worn o-rings.
Compression Style Faucets - this design is used for many double-handle faucets and is the old-fashioned style faucet (when shutting the faucet off, you usually can feel the rubber washer being squeezed inside the faucet.) Compression faucets have separate controls for hot and cold water and can be identified by the threaded stem assemblies inside the faucet body. Compression faucets all have washers or seals which control water flow and need to be replaced regularly over time. The replacement parts are inexpensive and easy to replace.
You may wonder what to do with a touch sensitive faucet when you want to clean it or just push its spout out of the way. What if the faucet keeps turning on and off all the time? A good faucet will distinguish a "touch" from a "grip" or "push". A "touch" from the point of view of the faucet is a short contact. You need to remove your hand in a fraction of a second for the faucet to react. If the hand stays longer, the faucet identifies it as a "grip" and does nothing. Smart touch recognition systems are present in all the touch faucets of acceptable quality. A faucet without the ability to recognize a touch is really not worth having. In my research on the touch faucet supply, I was not able to find a single one without this functionality. I′m sure that even if there are any at all, they would never be able to earn high customer points or positive comments. Knowing that, you don′t even have to dive deep into manuals and descriptions. It is enough to search for a particular faucet on your favorite online vendor site to see how others have rated it. Touch faucets without touch recognition cannot be considered quality products. If there are such for sale, they won′t be able to earn positive feedback.
