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.
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.
For modern faucets, the truth is quite opposite though. The touch function is reliable and under normal conditions always works as expected. These faucets cannot be activated by pets, and they are helpful for families with children.
