Wall-hung water closets must be supported by what type of structure?

Wall-hung water closets require a robust supporting structure that can accommodate their weight and provide stability. Metal carriers are specifically designed for this purpose, as they are engineered to support the load of the toilet while also ensuring secure installation to the wall. These carriers are typically made from sturdy materials like steel, providing the necessary strength and durability. Furthermore, metal carriers often include adjustable features to maintain the appropriate height and alignment, which is critical for ensuring proper function and aesthetics of the installation.

On the other hand, while wooden beams and brick walls can provide structural support, they may not offer the specialized design and adjustability required for wall-hung toilets. Plastic supports, while lightweight and potentially useful in some applications, generally lack the necessary strength to adequately support the weight and stresses exerted by wall-hung fixtures, leading to potential safety concerns or failures. Therefore, utilizing metal carriers is the best practice to ensure safety and reliability in installations of wall-hung water closets.
