TL;DR
A septic tank baffle is the wall or sanitary tee at each end of the tank that directs flow downward, keeping floating scum away from the inlet and outlet. The outlet baffle is the critical one, since it is the last barrier stopping grease and solids from washing into the drainfield; modern systems add an effluent filter inside it.
What it means
A septic tank baffle is the wall or sanitary tee at each end of the tank that directs flow downward, keeping floating scum away from the inlet and outlet. The outlet baffle is the critical one, since it is the last barrier stopping grease and solids from washing into the drainfield; modern systems add an effluent filter inside it. Concrete baffles corrode away over decades, and a missing one is among the most common defects flagged at point-of-sale septic inspections.
