Which fitting is used to secure a wall-mounted toilet?

• A. Carrier Fitting
• B. Flange
• C. Elbow
• D. Cap

Answer: (A)

A wall-mounted toilet is secured to the structure with a carrier fitting, which is a subframe installed inside the wall that bears the toilet’s weight and provides the mounting bolts to attach the toilet to the wall. This carrier sits behind the wall and carries the load, while the waste outlet connects through the wall to the drain. The other options don’t provide this in-wall support: an elbow is just a pipe bend, a cap closes an opening in a pipe, and a flange is the drain connection used for floor-mounted toilets rather than the wall-mounted securing system. So the carrier fitting is the component designed specifically to secure a wall-mounted toilet.
