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.
If a cat touches your touch sensitive faucet, it will, most likely, be too long a contact for the faucet to turn on. A canary landing on the faucet won′t activate it either. Well, how likely is a situation when your kitten would be sitting there and touching the faucet with its paw? Situations of this kind are extremely unlikely to happen. But even if they do once in a while, a good faucet has a built-in system that turns the water off automatically after a certain period of inactivity. It is usually configured somewhere between 3 and 5 minutes. So even if the faucet gets turned on by some unusual circumstance, the loss from that will be rather insignificant.
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.
One of the first things to know before shopping for a faucet is your hole configuration. Most sinks come with holes drilled to receive the faucet and sometimes accessories such as a sprayer, soap dispenser, hot beverage or filtered water faucet. One hole sinks are for single-control faucets, three hole are for single-control faucets with a sprayer and/or accessories and four holes are for single-control or two-handle sinks with various accessories. If you have an under-mount or apron front sink the holes are drilled into the countertop behind the sink.
