Which statement correctly identifies the use of SDR 35 inside a building?

• A. It may be used for Storm Drain
• B. Vent Pipe
• C. Water Service
• D. Waste Line

Answer: (C)

SDR 35 PVC is a drain-waste-vent (DWV) pipe, designed for carrying wastewater under gravity rather than for pressurized water. Inside a building, its typical role is in the waste line that carries used water and sanitary waste from fixtures to the building drain and on to the sewer or septic system. It isn’t meant for potable water service, which requires piping rated for drinking water pressure and compatibility (such as copper, CPVC, or PEX), and it’s not the standard material for vent piping. So the best understanding is that SDR 35 inside a building is used for the waste line, reflecting its DWV purpose.
