Kitchen Faucet Parts Under Sink

When your kitchen faucet starts leaking or malfunctioning, it can be a major inconvenience. While some faucet problems can be fixed with a quick tightening of the screws, others may require more extensive repairs. If you're not familiar with the parts of a kitchen faucet, it can be difficult to know where to start. This guide will provide you with an overview of the most common kitchen faucet parts under the sink, so you can better understand how your faucet works and how to fix it if necessary.

Faucet Body

The faucet body is the main part of the faucet and houses the other components. It is typically made of brass or stainless steel and has a hole for the spout and handle. The faucet body is also where the water supply lines connect.

Spout

The spout is the part of the faucet that dispenses water. It can be fixed or swiveling, and it may have a sprayer or aerator attached. The spout is typically made of brass or stainless steel, and it is held in place by a nut or screws.

Handle

The handle is the part of the faucet that you use to control the flow of water. It is typically made of plastic or metal, and it is attached to the faucet body by a screw or cartridge. The handle may have a single lever or two separate handles for hot and cold water.

Cartridge

The cartridge is a small, cylindrical device that controls the flow of water in the faucet. It is made of plastic or ceramic, and it is located inside the faucet body. The cartridge has two seals that prevent water from leaking, and it is held in place by a screw or clip.

Valve Seat

The valve seat is a small, flat surface that the cartridge seals against to stop the flow of water. It is typically made of brass or stainless steel, and it is located inside the faucet body. The valve seat may have a washer or O-ring to prevent leaks.

Aerator

The aerator is a small device that attaches to the end of the spout and mixes air with water to create a more forceful stream. It can also help to reduce splashing. The aerator is typically made of plastic or metal, and it is held in place by a screw or clip.

Sprayer

The sprayer is a small, handheld device that attaches to the end of the spout and dispenses water in a spray pattern. It is typically used for rinsing dishes or cleaning the sink. The sprayer is typically made of plastic or metal, and it is held in place by a screw or clip.
