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.
One of the first things to know before shopping for a faucet is your hole configuration. Most sinks come with holes drilled to receive the faucet and sometimes accessories such as a sprayer, soap dispenser, hot beverage or filtered water faucet. One hole sinks are for single-control faucets, three hole are for single-control faucets with a sprayer and/or accessories and four holes are for single-control or two-handle sinks with various accessories. If you have an under-mount or apron front sink the holes are drilled into the countertop behind the sink.
If you have never held a wrench in your hand, you probably do need a plumber to help you with the installation. But if you know how to connect an end of a pipe to the supply, you can do all the things on your own. Every faucet that is worth your attention will come with detailed instructions. But the process is highly intuitive, too. Basically, the lower part of the faucet comes through the installation hole on your sink or counter-top, hot and cold water pipes connected and the faucet fastened with nuts from beneath.
But when there are small children, the touch function comes in particularly handy. It is easier for them to get the water they need without asking adults for help. They don′t need to reach the handle and operate it. All they need to do is to tap somewhere on the faucet. It is not likely either that they would leave the water running. It has been found that children often find it fun to tap on the faucet to turn the water off.
