1. What is the primary purpose of a plumbing trap?
A. Filter solids from water
B. Prevent sewer gases from entering the building
C. Maintain water pressure
D. Control water temperature
Answer: B
Rationale: A trap holds water that forms a barrier to stop sewer gases from entering occupied
spaces.
2. What is the minimum water seal depth required for a standard residential trap?
A. 25 mm
B. 50 mm
