Which of the following is NOT a component of the tap housing?

The tap faceplate is indeed not a component of the tap housing. The tap housing primarily consists of structural elements that support the operational parts of the tap. Seizure screw mechanisms, right-angled input ports, and threaded mounting taps are integral to its function as they facilitate the connection and secure the tap in place. The tap faceplate, on the other hand, serves a different role, typically as an external cover or finishing piece that protects the internal mechanisms and provides aesthetic appeal, but it does not contribute structurally to the tap housing itself. Understanding the distinction among these components is essential for grasping how tap systems are assembled and function effectively.
