There may be a number of well-grounded reasons for not having touch sensitive faucets in your kitchen. The most widespread one is by far the price that is much higher for touch faucets than for their non-sensitive versions. Some other reasons might be affection for traditional ways, firm determination not to spoil yourself and your family with too effortless ways or plain reluctance to mess with batteries when they need to be changed.
To disassemble unscrew the setscrew and pull off handle. Though these faucets are washerless, they do have inlet and outlet seals that may leak, or sediment may build up inside the inlets and cause leaks. After removing the escutcheon cap, lift out the cylinder and clean the neoprene seals and cylinder openings. Be sure the faucet is in the "open" position when replacing seals.
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.
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.
