A faucet is a tool for delivering normal water from a domestic plumbing system. It could consist of the following components: spout, handle(s), lift up fishing rod, cartridge, aerator, mixing chamber, and drinking water inlets. If the handle is turned on, the valve opens and manages water flow adjustment under any temps or water condition. The faucet body is constructed of brass, though die-cast zinc and chrome-plated plastic are being used also.

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

Faucets must comply with water conservation laws. In america, bathroom basin faucets are now limited by 2 gal (7.6 L) of drinking water per minute, while shower and tub faucets are limited by 2.5 gal (9.5 L).

Faucets run an average of eight minutes per capita each day (pcd), regarding to a report by the American Water Works Relationship Research Basis completed in 1999 that was based on normal water use data gathered from 1,188 residences. In daily pcd use indoor drinking 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 fixtures, faucets migrated up to second at 11 gal (41.6 L) pcd. Tap use was 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 beyond your home and is lower for individuals who have an programmed dishwasher.The making process for faucets has become highly programmed, with computers controlling the majority of the machines. Efficiency and efficiency have thus advanced over the years.

Production and efficiency have increased over the years. The basic process consists of 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, followed by packaging and inspection. The faucet industry has also been influenced by environmental regulations, which have required special processes to be developed.
