A faucet is a tool for delivering drinking water from a domestic plumbing system. It could consist of the next components: spout, handle(s), lift up fishing rod, cartridge, aerator, mixing chamber, and normal water inlets. If the handle is fired up, the valve opens and control buttons the circulation adjustment under any temperature or normal water condition. The faucet body is usually made of brass, though die-cast zinc and chrome-plated plastic are also used.

Nearly all personal faucets are dual-control or single cartridge faucets. Some single-control types use a metal or plastic core, which operates vertically. Others use a metal ball, with spring-loaded plastic seals recessed in to the faucet body. The less expensive dual-control faucets contain nylon cartridges with rubber seals. Some faucets have a ceramic-disc cartridge that is a lot more durable.

Faucets must comply with water conservation regulations. In the United States, bathtub basin faucets are now limited to 2 gal (7.6 L) of water per minute, while tub and bathtub faucets are limited by 2.5 gal (9.5 L).

Faucets run an average of eight minutes per capita each day (pcd), matching to a report by the North american Water Works Association Research Basis completed in 1999 that was predicated on normal water use data accumulated from 1,188 residences. In daily pcd use indoor water use was at 69 gal (261 L), with faucet use third highest at 11 gal (41.6 L) pcd. In residences with water-conserving accessories, faucets migrated up to second at 11 gal (41.6 L) pcd. Faucet use was strongly related to home size. The addition of teens and adults increases water use. Tap use is also adversely related to the number of persons working outside the home and is lower for individuals who have an computerized dishwasher.The manufacturing process for faucets is becoming highly automated, with computers handling most of the machines. Efficiency and efficiency have thus increased over time.

Output and efficiency have improved over time. The basic process contains forming the main body of the faucet (some-times including the spout if no swivel is needed), applying a finish, and then assembling the many components, accompanied by presentation and inspection. The faucet industry in addition has been impacted by environmental regulations, which have required special processes to be developed.
