Function:
A tee baffle's primary purpose is to prevent solids (scum and sludge) from exiting the septic tank and entering the drain field, which could clog the pipes and cause premature system failure. 

 

Location:
Septic tanks typically have two baffles: one at the inlet (where wastewater enters) and one at the outlet (where wastewater exits to the drain field). 

 

Materials:
Baffles can be made from various materials, including concrete, PVC, or fiberglass, with PVC being a common choice in modern systems. 

 

How it Works:
The baffle directs the flow of wastewater downward and across the tank, allowing solids to settle and scum to rise to the top. The "cleaner" effluent in the middle of the tank is then drawn through the outlet baffle and into the drain field. 

 

Importance:
Proper baffle function is crucial for maintaining the efficiency and longevity of a septic system, as it prevents drain field clogs and ensures effective wastewater treatment.
