Ultimate Guide on 8 Parts of a Faucet: Names, Functions & Diagram

Overview of Faucet Parts

A faucet is a crucial part of plumbing systems, distributing water through its spout. Some important faucet parts are a handle, lift rod, cartridge, aerator, mixing chamber, and water inlets. Faucet bodies are usually made of brass, but die-cast zinc and chrome-plated plastic are also used. All parts of a faucet are manufactured precisely and assembled to make a faucet a working assembly.

When you turn the handle, the valve opens, allowing control over water flow and temperature. Residential faucets typically have single or dual-control cartridge designs. Some single-control types use a vertical metal or plastic core, while others use a metal ball with spring-loaded rubber seals. Cost-effective dual-control faucets often have nylon cartridges with rubber seals. Alternatively, certain faucets use a durable ceramic disc cartridge for longer life.

Parts of a Faucet and Their Functions

Faucet Body

A faucet body is like the heart of a faucet in plumbing systems. It houses important parts that control water flow and temperature, such as the valve, handle, and spout. These elements allow users to manage water activation, temperature, and flow direction.

Faucet bodies come in various styles, from simple and practical to detailed and decorative. They can be made of different materials like metal, brass, chrome, or plastic, depending on the desired look and application. Faucet bodies are essential in plumbing fixtures, impacting both how the faucet works and how it looks.

Choosing the right faucet body design is crucial for a smooth water supply in every household. Among the options available, the single-hole design is universal. It combines hot and cold water in a one-piece casting with one or two handles.

Adjusting Ring

An all-purpose seal made of versatile materials engineered to securely seal any faucet’s joints and prevent leaks or water damage.


The term spout refers to the part of the faucet from which water flows. It is the open end or nozzle through which water is distributed.

The design and shape of the spout can vary depending on the type and style of the faucet. Some faucets have a straight spout, while others may have a curved or angled spout. The spout is an important part of a faucet, as it determines the direction and flow of water when the faucet is turned on.


The aerator is a small yet powerful part of modern faucets. It is crafted from fine mesh; it divides water flow into tiny streams, injecting air to enhance water quality.

This device boosts oxygen levels, saves water by controlling flow, and minimizes splashing. It provides an eco-friendly solution for households and businesses, maintaining a high-pressure feel while reducing waste.


The faucet handle is the primary method of controlling water in sinks and showers. It is often located on top of the faucet. It allows you to regulate the temperature and pressure of the water by spinning it or moving it up and down.

Handles can be one piece or separate for hot and cold water. In a one-piece handle, we can allow the flow of hot and cold water by moving the handle up and down or moving left or right. In brief, the faucet handle is essential for simply controlling the flow of water in plumbing fixtures.


A faucet valve, also known as a tap, is a crucial part of plumbing systems. It controls the flow of liquids, usually water, in places like kitchens and bathrooms. It lets us do tasks like handwashing and dish cleaning.

Faucet valves have a basic design with a handle or knob for users to open or close the valve, regulating water flow. There are different types of faucet valves, like compression, ball, cartridge, and ceramic disc valves, each with its way of controlling flow, each with pros and cons.

Faucets come in various styles and materials to match both looks and function. Some have extra features like temperature control and water-saving mechanisms. Choosing the right faucet valve depends on factors like your plumbing system, how you plan to use it, and personal preferences.

A faucet mount is a simple water filtration system that easily attaches to a standard kitchen faucet. It helps to enhance drinking and cooking water quality. It reduces impurities and improves taste without requiring complex plumbing adjustments.

Comprising a housing, filter cartridge, and a switch, faucet mounts offer easy switching between filtered and unfiltered water. The filter cartridge is crucial for eliminating contaminants like chlorine.

Cost-effective and practical, faucet mounts provide clean, filtered water without the need for a separate pitcher or complex under-sink setup. However, their effectiveness varies by brand and model. Regular maintenance, such as timely filter cartridge replacement, is essential for optimal performance.

Cold and hot Water Supply

These are the supply lines of the cold & hot water to the faucet’s body.
