Delta shower faucets typically consist of the following parts: the handle, the cartridge, the escutcheon, the supply tubes, and the showerhead. Each of these components plays a crucial role in delivering water to your shower. When one of these parts malfunctions, it can cause your faucet to stop working entirely.
