What are horizontal pipes in wastewater systems called?

1. Stacks

2. Branches

3. Columns

4. Risers

The correct answer is: Branches

In wastewater systems, horizontal pipes are referred to as branches. Branches are crucial components of a plumbing system as they serve to direct the flow of wastewater from various sources, such as fixtures, to the main sewer line or drainage system. These pipes run horizontally, connecting vertical stacks and cleaning the overall layout of the wastewater management system. The other options refer to different elements within plumbing and waste disposal systems. Stacks are vertical pipes that carry wastewater or vent air to the outside, while risers are also vertical pipes but are specifically used to transport the materials upwards in the system. Columns typically refer to structural support elements in buildings rather than components of wastewater systems. Understanding these distinctions is essential for effectively navigating plumbing design and terminology.
