What is the meaning of "drainage slope" in plumbing?

Drainage slope refers to the angle at which drainage pipes are installed to ensure that wastewater flows effectively by the force of gravity. This slope is crucial in preventing blockages and ensuring that waste moves smoothly through the plumbing system. When pipes are set at the correct drainage slope, it helps maintain a consistent flow rate, reduces the likelihood of standing water, and minimizes the risk of clogs that can occur if the flow is too slow.

This concept is fundamental in plumbing design and installation, as improper slope can lead to a range of issues, including sewage backups and pipe damage. Understanding the appropriate angle is essential for any plumbing professional to ensure a properly functioning drainage system.
