Whether the job is residential or commercial, it is our policy to empty the tank completely. To ensure that all septage is removed from the tank we back flush, which is a form of cleaning the tank, then the tank is emptied again. We confirm that the inlet and outlet baffles are in place, check the tank for any potential problems, and clean the effluent filter (when applicable). To minimize potential lawn damage, our drivers will not drive the truck on your lawn. Each truck is equipped with at least 200 feet of hose.
