Uncontrolled operation is the main fear that makes people who would otherwise have chosen a touch sensitive faucet decide to have a non-sensitive one. It is easy to believe that such faucets are not suitable for families with young children or pets that stay in the kitchen.
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.
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.
To disassemble unscrew the bonnet from the faucet, using slip-joint pliers. Remove the valve stem, keeping in mind this has reverse threads, so unscrew it by turning it clockwise. Older compression faucets may have corroded handles that can be difficult to remove. Most hardware stores and rental centers have a specialty tool called a Handle Puller which makes the job easier.
