Red Seal Plumbing Practice Exam

The main types of interceptors are designed to collect:

1. Dust, Pollen, Mites

2. Grease, Oil, Solids

3. Plastics, Metals, Glass

4. Water, Air, Soil

The correct answer is: Grease, Oil, Solids

Interceptors are designed to collect materials that would otherwise cause harm or damage in a particular system. Dust, pollen, and mites are typically too small to cause significant issues, so interceptors are typically not designed to collect them. Plastics, metals, and glass are also not commonly collected by interceptors, as they are inert materials that do not pose a threat. Water, air, and soil are typically not collected by interceptors either, as they are essential components of most systems and are not considered harmful. Therefore, the main types of interceptors are designed to collect materials that can cause harm or damage, such as grease, oil, and solids.
