Cartridge Faucet - this washerless faucet is identified by the narrow metal or plastic cartridge inside the faucet body; and it is available in both single and double handled cartridge designs. Cartridge faucets have a hollow cartridge insert that lifts and rotates to control the flow and temperature of water. Dripping at the spout occurs when the cartridge seals wear out. Leaks at the base are caused by worn o-rings.
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 decision may be tough at times. But it does not have to be like buying a pig in a poke. With a little research, you can find a lot of useful feedback from existing users about how the touch sensitivity works in different kitchen faucets. Some faucets have tens, if not hundreds, of reviews on the largest online vendor websites like Amazon. The number of reviews and the ratings given can be a good indication of the quality of the faucet. You can see if there are a lot of people having issues with the touch sensitivity in a particular faucet.
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.
