Single hole faucets, also known as single-handle faucets or monobloc faucets, are a popular choice for modern kitchens and bathrooms. Characterized by their sleek design and single lever control, they offer a minimalist aesthetic and ease of use. But beneath the surface lies a complex mechanism that requires careful handling during disassembly. Understanding the components and how they interact is crucial for a successful disassembly.

The Anatomy of a Single Hole Faucet

Before diving into the disassembly process, let’s familiarize ourselves with the key components of a typical single hole faucet:

* **Handle:** Controls the water flow and temperature.
* **Set Screw:** Secures the handle to the faucet body.
* **Decorative Cap/Cover:** Conceals the set screw and adds to the faucet’s aesthetic appeal.
* **Cartridge Nut/Retaining Clip:** Holds the cartridge in place.
* **Cartridge:** The heart of the faucet, controlling the mixing of hot and cold water.
* **Faucet Body:** The main structure of the faucet.
* **Water Supply Lines:** Connect the faucet to the hot and cold water supplies.
* **O-Rings and Seals:** Prevent leaks between components.
