What is meant by "drainage slope"?

The term "drainage slope" refers to the angle or gradient at which drainage pipes are installed to facilitate the efficient flow of wastewater. When pipes are sloped correctly, gravity aids in the movement of waste away from fixtures and toward the drainage system, helping to prevent blockages and backups.

A proper drainage slope is crucial; if the slope is too steep, it can cause rapid flow that may not allow solids to be carried along effectively. Conversely, if the slope is too shallow, it can lead to stagnant water and accumulation of debris, which can eventually clog the system. Therefore, understanding and implementing the correct drainage slope is vital for maintaining an effective plumbing system.
