Multiple Choice

Which installation characteristic helps prevent sewer blockage buildup?

Maintaining a steady, uniform flow along the sewer run is what helps prevent solids from settling and forming blockages. When the pipe is installed with a consistent slope and cross-section, the wastewater velocity stays in a range that keeps solids in suspension and carried downstream. Any abrupt change—like a sudden step in invert elevations, a change in diameter, or misaligned joints—can create low-velocity pockets or eddies where sediment can deposit, leading to buildup. Material and wall thickness matter for durability and roughness, but they don’t control the ongoing flow conditions as directly as a uniform installation does, which is why uniformity is the best choice for preventing blockages.
