It is quite obvious that the touch feature is powered by electricity. Sometimes people ask whether the faucets need to be connected to the mains. They think it might be dangerous. Others mistrust the very idea of electricity and water being together in a faucet. In fact, the touch sensitive faucets are powered by a set of four or six 1.5 V batteries. The voltage reached by such a pack does not exceed 9 volts, which is considered safe voltage even by the strictest regulations. The electricity, however weak, never comes in contact with water. In a typical touch sensitive faucet, water runs inside pipes made from non-conductive materials. So there is no threat whatsoever that could be attributed to the use of electricity in touch sensitive faucets.
Second - Disassemble the Faucet: The same basic principals apply to all faucet types when starting to take a faucet apart for repair or replacement. Keep all parts and layout in the order you take them apart. This will help you both put the faucet back together and identify the parts to be replaced. See below for specific variations in faucet dis-assembly.
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.
Ball-style Faucet - this washerless faucet has a single handle and is identified by the hollow metal or plastic ball inside the faucet body which controls water temperature and flow. Many have a rounded cap with knurled edges located under the faucet handle. Dripping at the faucet spout is caused by worn valve seats, springs, or a damaged ball. Leaks around the base of the faucet are caused by worn o-rings.
