Ask AI: The supply and drainage subsystems of a plumbing system are interrelated and often overlap. true or false

**True.** The supply and drainage subsystems of a plumbing system are interrelated and often overlap. While the **supply subsystem** delivers fresh water to fixtures and appliances, and the **drainage subsystem** removes wastewater, their pipes typically run in close proximity and sometimes even share pathways through walls, floors, and ceilings. Both subsystems often connect at the same fixtures (such as sinks, toilets, and showers), making coordination and integration essential during installation and maintenance. Proper planning ensures they function efficiently together, preventing cross-contamination and leaks.
