How Does the Faucet Look Like in Your House?


As we know, water is indispensable in our daily life. How do you get the water? In ancient times, people may go the river side, using different vessels to carry water to home. Nowadays, we don't need to pay so much effort. We could get the water as soon as we open the water faucet, or the taps.

A tap http://www.ecvv.com/company/l-guardtire/products.html, which is also called spigot and faucet in the U.S., is a valve controlling release of liquids or gas. In the British Isles and most of the Commonwealth, the word is used for any everyday type of valve, particularly the fittings that control water supply to bathtubs and sinks. In the U.S., the term "tap" is more often used for beer taps, cut-in connections, or wiretapping. "Spigot" or "faucet" are more often used to refer to water valves, although this sense of "tap" is not uncommon, and the term "tap water" is the standard name for water from the faucet.

Water for baths, sinks and basins can be provided by separate hot and cold taps. This arrangement is common in older installations, particularly in public washrooms and utility rooms or laundries. In kitchens and bathrooms, mixer taps are commonly used. In this case, hot and cold water from the two valves is mixed together before reaching the outlet, allowing the water to emerge at any temperature between that of the hot and cold water supplies. Mixer taps were invented by Thomas Campbell of Saint John, New Brunswick and patented in 1880.

For baths and showers, mixer taps frequently incorporate some sort of pressure balancing feature so that the hot or cold mixture ratio will not be affected by transient changes in the pressure of one or the other of the supplies. This helps avoid scalding or uncomfortable chilling as other water loads occur (such as the flushing of a toilet). Rather than two separate valves, mixer taps frequently use a single, more complex, valve controlled by a single handle. The handle moves up and down to control the amount of water flow and from side to side to control the temperature of the water. Especially for baths and showers, the latest designs do this using a built in thermostat. These are known as thermostatic mixing valves, or TMVs, and can be mechanical or electronic. There are also faucets with color LEDs to show the temperature of the water.

There is a kind of beer taps. Beers brewed and served in the traditional way (typically cask ale) do not use artificial gas. Taps for cask beer are simple on-off valves that are hammered into the end of the cask. When beer is served directly from the cask, as at beer festivals and some pubs, it simply flows out of the tap and into the glass. When the cask is stored in the cellar and served from the bar, as in most pubs, the beer line is screwed onto the tap and the beer is sucked through it by a hand-operated low-pressure pump on the bar.
