Faucets are essential fixtures in every home, playing a crucial role in daily tasks like washing dishes, filling pots, or cleaning hands. They often go unnoticed until something goes wrong. But understanding faucet parts can make maintenance and troubleshooting a breeze.

This guide aims to provide you with everything you need to know about the parts of a faucet, how it works, and how to maintain it. Plus, we'll cover the costs of repairs and whether it's better to DIY or hire a professional.  

Common Sink Faucet Parts and How Do They Work

Understanding the main parts of a faucet is essential for any homeowner. Each component plays a crucial role in how the faucet functions.

Knowing how they work together will help you identify any issues more easily. Here's a breakdown of the common sink faucet parts:

1. Handle

The handle is perhaps the most noticeable part of the faucet. It is used to control the flow of water and sometimes its temperature.

Depending on the design, a faucet may have one handle or two — one for hot and one for cold. The handle connects to the internal mechanism that opens and closes the valve, allowing water to flow when turned.

How it works: When you turn the handle, it moves a valve inside the faucet, controlling the flow of water. Some modern faucets have a lever handle that is easier to use and requires less force.

2. Spout

The spout is the part of the faucet where the water exits. It is typically located at the end of the faucet body. It is shaped to direct the water flow where it's needed, such as into a sink or a basin.

How it works: The spout simply directs the water once the valve is open. Some faucets have adjustable spouts for flexibility, while others may have a fixed spout that stays in one position.

3. Valve

The valve is the core part of the faucet that controls the water flow. It can be found inside the faucet body, and it is responsible for opening and closing the water supply. Depending on the faucet style, the valve may be ceramic, compression, or ball-type.

How it works: When you turn the handle, it rotates or lifts a valve mechanism that either blocks or allows water to flow. Ceramic valves are more durable. Compression valves tend to wear out faster, leading to leaks.

4. Aerator

The aerator is a small and mesh-like device located at the tip of the faucet spout. Its primary function is to mix air into the water flow, which reduces water splashing and conserves water.

How it works: As water passes through the aerator, air is forced into the stream, making the water flow smoothly and efficiently.

This also helps reduce water usage by limiting the amount of water flowing out at any given time.

5. Body

The body of the faucet is the main structure that holds all the parts together. It houses the valve, handle, and other internal components. It is typically made from metals like brass or stainless steel. But it can also be made from other materials like plastic or zinc.

How it works: The body is designed to contain the internal plumbing and mechanisms that allow the faucet to function. It ensures the faucet remains stable and that all components stay in place.

6. Mount and Escutcheon Plate (Deck mount/Wall mount)

The mount and escutcheon plate secure the faucet to the sink or countertop. The mount is the base, while the escutcheon plate is the decorative trim around the faucet.

These faucet parts are especially important for keeping the faucet in place and ensuring a secure installation.

How it works: The mount holds the faucet to the sink or countertop, while the escutcheon plate covers any gaps between the faucet and the surface.

Depending on the faucet design, these parts may be attached to the sink via screws or adhesives.

Some Less-Known Parts of a Faucet

While many people are familiar with the main sink faucet components, several lesser-known parts play a significant role in the faucet's performance and longevity. Here's a look at some of these hidden but important faucet parts:

1. O-rings

O-rings for sinks are small rubber or silicone seals found in various parts of the faucet, such as around the handle or valve. These seals help prevent leaks by creating a watertight seal between moving parts.

2. Cartridge or Stem

The cartridge or stem is the internal mechanism that controls the flow and temperature of water in the faucet. It is located inside the faucet body. It is responsible for regulating the water pressure and the temperature when you turn the handle.

3. Dishwasher Drain Hose

While not part of the faucet itself, the dishwasher drain hose is connected to the faucet through the air gap or directly to the sink drain.

This hose helps divert wastewater from the dishwasher away from the sink. It helps prevent backflow and ensures the wastewater is safely drained.

4. Supply Line Adapters

Supply line adapters connect the faucet to the home's water supply lines. These adapters come in different sizes to fit the specific plumbing in your home. They play a crucial role in making sure the faucet has a steady flow of water.

5. Diverter Valve

The diverter valve is typically found in faucets that have a shower or tub spout attachment. It controls whether water flows out of the faucet or diverts to another outlet, such as a showerhead.

The Materials Used in the Anatomy of a Faucet

When choosing a faucet, it's important to consider the materials used in its construction. The material not only affects the appearance of the faucet but also impacts its durability, resistance to corrosion, and overall performance.
