Req 5a — Clearing a Drain or Trap

A sink that drains slowly is giving you an early warning. Somewhere in the path below the fixture, hair, grease, soap residue, or debris is narrowing the flow. Clearing a drain or trap teaches you to think about plumbing as a path water has to travel, not just as a hole in the sink.

What a Trap Does

The trap is the curved section below many drains. It holds a small amount of water that blocks sewer gases from coming back into the room. Because it is low and curved, it is also a common place for debris to collect.

Start With the Least Invasive Fix

Depending on the situation and your supervising adult’s guidance, you may start with:

• Clearing visible debris at the drain opening
• Using a plunger correctly
• Opening and cleaning a trap
• Reassembling and testing for leaks afterward

This requirement teaches you to prepare before loosening anything. Water always comes out faster than many beginners expect.
