Faucet manufacturers make several types of replacement kits for ball-type faucets; some kits have only the springs and neoprene valve seats, while better kits also have the cam and cam washer.
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.
Pullout faucets have a spray head that pulls out towards you, whereas a pull-down faucet has a spray head that pulls down toward the bottom of the sink. Both options help you clean the sink and wash produce or water plants. The pull-outs are the fastest growing in popularity of any faucet in the industry with good reason, they are the perfect combination of style and function. A button or toggle control makes it easy to go from aerated stream to spray. Look for one that swivels 360 degrees for easy access to all areas of your sink.
A good touch sensitive kitchen faucet will never turn on by itself. They can be used on any type of sinks including metal ones. In the dawn of touch sensitivity in faucets, they had a number of problems including turning on too often by accident. In modern faucets, these problems are eliminated. It is wise, however, not to rely on just any touch sensitive faucet out there. There are cheap faucets without even name or brand that offer you a bunch of advanced features. If you buy one of them, it′s a gamble. In my opinion, the safest way to go is finding a brand whose touch sensitive faucets have proved to be reliable. The information available online can help a lot. User ratings, comments and reviews can give you a better idea about the quality. Be aware though that even the best faucet won′t work as expected if installed on a metal sink with insufficient insulation. In this case, the sink itself can become a "continuation" of the faucet, and it will turn on just by touching the sink. The problem will be gone when the faucet is installed with a proper insulation.
