How far can the vertical piping distance be when installing a floor outlet type toilet piping?

10 inches
15 inches
20 inches
25 inches

The correct answer is: 20 inches

The correct answer indicates that when installing a floor outlet type toilet piping, the maximum vertical distance for the piping is set at 20 inches. This stipulation is crucial in maintaining proper function, as it ensures adequate drainage and prevents issues related to waste backup or insufficient flow. In plumbing codes, specific measurements are provided to ensure plumbing systems operate efficiently and safely. A 20-inch maximum vertical distance strikes a balance, allowing for flexibility in installation while still adhering to best practices for slope and gravity drainage. Maintaining this distance is key to preventing potential problems such as clogs or misalignments that could arise with greater vertical distances. This standard is designed to promote long-term efficiency and reliability in toilet plumbing systems.
