Identifying the Type of Faucet

Identifying the type of kitchen faucet is a crucial step before starting any repair work. Each type of faucet has different mechanisms and components, and knowing which type you have will guide you in selecting the right repair techniques and replacement parts.

Compression faucets are one of the oldest types and are commonly found in older homes. They operate using a screw that compresses a rubber washer, creating a seal to stop the flow of water. Compression faucets have separate hot and cold handles, and they tend to develop leaks more frequently due to the wear and tear of the rubber washers. Identifying a compression faucet is straightforward; if your faucet has two separate handles and you feel resistance when turning them off, it’s likely a compression faucet.

Ball faucets are a common type of single-handle faucet. They use a ball joint to control the flow and temperature of the water. The ball mechanism is housed within the faucet body and is operated by a single lever. Ball faucets are prone to leaks due to the wear of the internal seals and springs. Identifying a ball faucet is easy if your faucet has a single handle that moves in a spherical motion to adjust the water flow and temperature.

Cartridge faucets can be either single-handle or double-handle. They use a movable cartridge to control the flow of water. The cartridge can be made of brass, plastic, or ceramic. Cartridge faucets are known for their durability and ease of repair. To identify a cartridge faucet, look for a smooth, consistent action when turning the handle(s) on and off, with no noticeable resistance or grinding.

Disc faucets are a modern and durable type of faucet that uses a pair of ceramic discs to control the flow of water. These faucets are usually single-handle and are known for their reliability and low maintenance. Identifying a disc faucet involves checking for a wide, cylindrical body that houses the ceramic disc cartridge. The handle typically moves in a smooth, up-and-down, and side-to-side motion to control the water flow and temperature.

Once you have identified the type of faucet, the next step is to gather the appropriate replacement parts. Most faucet manufacturers provide detailed diagrams and part numbers for their products, which can be found online or in the product manual. Using these resources can help you find the exact parts needed for your specific faucet model, ensuring a proper fit and a successful repair.
