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.
The faucets with detachable spray wands have become extremely popular during the last decades. But there is always some doubt whether the pull-out wand will have a snug enough fit into its dock. If the wand does not sit very well, the faucet loses a lot. It can be beautifully designed, but if the spray head does not sit where it should, the whole faucet will look cheap and inferior. That is why the leading manufacturers of kitchen faucets have done their best to secure the wand firmly in its place.
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.
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.
