A bathtub mixer tap is a plumbing fixture designed to provide both hot and cold water, allowing users to control the temperature and flow for bathing. Understanding its components is essential for proper installation, maintenance, and efficient operation.
The valve body is the main structure of the tap, typically made of brass or other corrosion-resistant metals. It houses the internal mixing mechanism and connects to the hot and cold water supply lines. The valve body is designed to withstand water pressure and provide long-term durability.
The mixing cartridge or ceramic disc cartridge is the core component responsible for blending hot and cold water. When the handle is moved, the cartridge adjusts the ratio of hot to cold water, allowing precise temperature control. Ceramic discs are preferred for their durability and smooth operation, reducing leaks and wear over time.
The spout directs water from the mixer tap into the bathtub. Some spouts are fixed, while others swivel to provide flexibility. In taps with a shower attachment, the spout may include a diverter that redirects water to a hand shower or overhead shower.
The handle or lever allows the user to control water flow and temperature. Single-lever handles combine both functions into one control, while dual-handle designs separate hot and cold adjustments. The handle connects directly to the cartridge inside the valve body.
Additional components include O-rings and seals, which prevent leaks at connection points, and mounting hardware, which secures the tap to the bathtub or wall. Some mixer taps also feature diverters, allowing water to be switched between the spout and showerhead efficiently.
