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.
But even if the children forget to turn the water off, all touch sensitive faucets from reliable manufacturers come with security systems that turn the water off automatically after a certain period of inactivity.
Important: After making repairs to a disc faucet, it is imperative the handle in the ON position, then open the shutoff valves slowly. The ceramic discs can be cracked by the sudden release of air from the faucet. Once the water is running steadily, it is safe to close the faucet.
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.
