Parts of a Tap or Faucet An In Depth Guide

Table Of Contents:


Understanding the various parts of a tap or faucet is crucial for homeowners, DIY enthusiasts, and anyone interested in home maintenance or renovation.

Whether you're planning to repair, replace, or simply curious about how taps operate, this guide will provide you with a comprehensive overview of the components that make up a tap.

At Tapron UK, we believe in empowering our customers with knowledge to make informed decisions about their plumbing fixtures.

The Anatomy of a Tap

  1. Handle(s): Taps can have one or two handles. Single-handle taps allow for easier control of both water temperature and flow with one lever. Dual-handle taps feature separate handles for hot and cold water, offering precise temperature adjustment.

  2. Spout: The spout is the part of the tap where water flows out. Its design can vary widely, from traditional curved shapes to modern, straight lines, affecting both the tap's look and the water's flow pattern.

  3. Valve: The valve controls water flow through the tap. Types of valves include ball, disc, cartridge, and compression valves, each with its own mechanism for regulating water flow and temperature.

  4. Aerator: Located at the tip of the spout, the aerator mixes air with water to produce a smoother flow, reduce splashing, and increase efficiency by limiting water use.

  5. O-Rings: O-rings are small rubber rings that seal the joint between different parts of the tap to prevent leaks. They are found in various locations, including around the valve and under the handle.

  6. Cartridge: In single-handle taps, the cartridge is a cylindrical part that moves within the valve body to control the mix of hot and cold water and regulate flow.

  7. Escutcheon Plate: This is a decorative plate that covers the hole in the sink or wall through which the tap is installed. It also helps to prevent water from leaking into the hole.

  8. Supply Lines: These are the hoses or pipes that connect the tap to the home's water supply, delivering hot and cold water to the faucet.

  9. Washers: Washers are used in compression valve taps to create a water-tight seal that prevents leaks. They can wear out over time and may need to be replaced.

  10. Mounting Hardware: This includes nuts, bolts, and screws used to secure the tap in place on the sink or countertop.

Common Tap Types and Their Components

  • Ball Faucets: Utilize a single handle that moves over a ball-shaped cap right above the base of the faucet spout.
  • Disk Faucets: Characterized by a single lever on top of a wide cylindrical body.
  • Cartridge Faucets: Can have either a single or double handle that moves up and down to regulate flow and left and right to control temperature.
  • Compression Washer Faucets: The oldest type of faucet, typically featuring two handles that compress a rubber washer to control water flow.
