What type of item should be avoided in a septic system to maintain functionality?

Fats and oils should be avoided in a septic system because they do not break down easily and can lead to clogs and systemic failures within the septic system. When fats, oils, and grease enter the tank, they can create a scum layer that inhibits the proper breakdown of waste by bacteria. This scum can also accumulate in the pipes, leading to blockages and inefficient drainage. Maintaining clear pathways in the septic system is essential for its functionality, and avoiding substances that disrupt this balance is crucial for effective operation.

In contrast, human waste, biodegradable products, and toilet paper are generally designed to break down within a septic system, provided that they are used properly and in moderation. These materials are meant to be treated by the bacteria in the tank, allowing the system to process waste effectively.
