水龍頭按閥芯來分，可分為橡膠芯(慢開閥芯)、陶瓷閥芯(快開閥芯)和不銹鋼閥芯等幾種。影響水龍頭質量關鍵的就是閥芯。使用橡膠芯的水龍頭多為螺旋式開啟的鑄鐵水龍頭，現在已經基本被淘汰；陶瓷閥芯水龍頭是近幾年出現的，質量較好，現在比較普遍；不銹鋼閥芯是近才出現的，更適合水質差的地區。

Faucets can be classified by valve core, including rubber core (slow opening valve core), ceramic valve core (fast opening valve core), and stainless steel valve core. The most critical factor affecting the quality of faucets is the valve core. Rubber core faucets are mostly cast iron faucets with spiral opening, which have been basically phased out now; Ceramic valve core faucets have emerged in recent years with good quality and are now quite common; Stainless steel valve cores have only recently emerged and are more suitable for areas with poor water quality.

　　水龍頭是一個控制水的流止的閥門。英國盥洗盆或是浴缸的水龍頭通常是冷、熱分離的兩端。在美國以及其他，大多是混合式水龍頭。后者是在冷、熱水混和后才出水，因此可以控制不同的溫度來用水。而水龍頭主要原料為銅與鋅合金。

A faucet is a valve that controls the flow of water. The faucet of a British washbasin or bathtub is usually separated from the hot and cold ends. In the United States and other countries, most are hybrid faucets. The latter only releases water after mixing cold and hot water, so different temperatures can be controlled to use water. The main raw materials for faucets are copper and zinc alloys.

　　如果單獨安裝水龍頭，自來水不一定是熱的或是冷的。通常熱的水龍頭一般有一個紅色指示燈或是符號，而冷水龍頭一般有一個藍色或綠色指示燈或是符號。在英語為母語的，水龍頭也經常標有一個“H”或“C”代表熱或冷。大多數住宅房、商業和工業屋門前都有個水龍頭，他們都配有一個內孔為四角型的開關，以免路人亂用水。

If a faucet is installed separately, the tap water may not be hot or cold. Usually, hot faucets have a red indicator light or symbol, while cold water faucets usually have a blue or green indicator light or symbol. In native English speaking countries, faucets are often marked with an "H" or "C" to represent hot or cold. Most residential, commercial, and industrial houses have a faucet in front of their door, which is equipped with a square shaped switch to prevent passersby from using water indiscriminately.
