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.
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.
Second - Disassemble the Faucet: The same basic principals apply to all faucet types when starting to take a faucet apart for repair or replacement. Keep all parts and layout in the order you take them apart. This will help you both put the faucet back together and identify the parts to be replaced. See below for specific variations in faucet dis-assembly.
Disc Faucet - a top-quality fixture, the disc faucet has a single handle and is identified by the wide cylinder by the faucet body. The cylinder contains a pair of closely fitting ceramic discs that regulate the water flow: a movable upper disc turns or lifts and lowers against a fixed lower ceramic disc. Most ceramic disc faucets don′t drip or leak because they′re made to be almost maintenance free. Dripping at the spout occurs when the neoprene seals or cylinder openings are dirty. If the faucet continues to leak after cleaning, then install a new cylinder.
