When are heel or side inlet quarter or closet bends permitted according to the Illinois Plumbing Code?

When connecting to water supply lines
When connecting to gas lines
When the fixture connecting is vented
When the fixture is elevated

The correct answer is: When the fixture connecting is vented

The correct answer is centered around the permissions granted for the use of heel or side inlet quarter or closet bends, specifically highlighting the necessity of venting for the fixtures they connect. According to the Illinois Plumbing Code, these types of bends are utilized to optimize space and improve flow when connecting fixtures to drainage systems. The reason venting is essential in this context is that proper ventilation prevents the creation of a vacuum in the drainage system, which could lead to inefficient drainage or the risk of sewer gases entering the living space. Therefore, when fixtures that utilize heel or side inlet bends are properly vented, it ensures that these connections function safely and effectively, adhering to plumbing standards that promote both performance and health safety. Other choices, such as connecting to water supply or gas lines, are not relevant to the purpose of these specific plumbing components, and elevation of the fixture does not directly relate to the requirements set forth in the code regarding the use of these types of bends. Thus, the focus on venting is crucial for ensuring compliance with plumbing regulations and effective operation of the system.
