What is the function of a trap in a plumbing system?
Correct Incorrect A plumbing trap, usually found beneath sinks, tubs, and showers, holds a small amount of water to act as a barrier against sewer gases entering the home. The trap must be properly vented to work efficiently and should be maintained to prevent clogs. Keeping the trap clear ensures it keeps unpleasant odors out and prevents plumbing issues.
