When can SDR 35 be used inside a building?

• A. Storm Drain
• B. Vent Pipe
• C. Water Line
• D. Waste Line

Answer: (A)

SDR 35 PVC is a relatively thin-walled pipe designed for underground storm drainage and non-pressurized drainage within a building. It’s chosen for storm sewer paths because it’s economical for gravity-driven water and is approved for storm drainage contexts, including interior storm lines. It isn’t used for potable water, vent piping, or sanitary waste lines inside a building because those applications require pipes with different wall thicknesses, material properties, and code approvals to handle pressure, gases, temperatures, and potable-water safety. So the best fit inside a building is for a storm drain, where the pipe carries stormwater rather than drinking water or wastewater.
