Petroleum-contaminated soil surrounds a planned water-service route. Which material and routing issue needs approval?
- AA thinner pipe wall
- Material suitability and an approved protective routing or method
- COnly the pipe's exterior color for the described plumbing system and documented site conditions
- DHigher water temperature
Why B is correct
The best answer is: Material suitability and an approved protective routing or method. Some contaminants can permeate or degrade piping and joining materials. Site conditions, manufacturer limitations, health protection, replacement soil, sleeving, or rerouting require design and authority review. The transferred field condition applies the same plumbing design, installation, service, or safety principle to a different project setting. The alternatives omit a prerequisite, conflict with the approved method, or fail to control the stated sanitation or physical hazard.
