What should be avoided to prevent clogs in a single chamber foul water system?

Fat should be avoided in a single chamber foul water system because it tends to solidify and accumulate on the interior surfaces of pipes over time. This accumulation can lead to significant clogs and blockages, restricting the flow of wastewater and potentially causing backups and overflow issues. When fats are introduced into the system, they adhere to other materials, creating a buildup that can be difficult to manage and remove.

In contrast, while plastics and glass can also contribute to clogging if they are not disposed of properly, their impact is generally less significant than that of fat, which can create a persistent and growing obstruction. Liquid waste, although it can sometimes include solids, is typically not a problem in moderate amounts since it flows readily and can help to carry solids through the system. As such, managing or eliminating fats and greases from disposal practices is crucial for maintaining the efficiency and effectiveness of a foul water drainage system.
