Septic Baffle and Tee Repair in Mandan
Baffles and tees keep scum and solids in the tank so they do not flow out into the leach field. Concrete baffles crumble from hydrogen sulfide gas, and plastic tees can break off. When they fail, solids clog the field fast. We replace damaged baffles with durable PVC tees and add an effluent filter where appropriate.
