What is the diameter required for shower waste outlets in Illinois Plumbing Code practice?

1 1/2 inches
2 inches
2 1/2 inches
3 inches

The correct answer is: 2 inches

The correct answer is the requirement for shower waste outlets to have a diameter of 2 inches. This size is specified in the Illinois Plumbing Code to ensure that adequate drainage is provided for shower installations. A 2-inch diameter allows for sufficient water flow and helps prevent blockages from hair and soap residues, which are common in shower settings. By using a width that balances effective drainage with appropriate sizing for the typical discharge from a shower, this requirement helps maintain plumbing systems' performance and longevity. In contrast, a smaller diameter could result in slower drainage and increased chances of clogs, while larger diameters may be unnecessarily excessive for the flow rates of showers, leading to increased costs and complications in installation without significant benefits.
