A professional septic system service involves much more than just pumping out the tank. It includes a comprehensive inspection of all components of the system, such as the distribution lines, seepage pits, and leaching fields. The technician must also check for signs of problems such as clogs or leaks from the tank itself. In addition to this, they must test soil samples to ensure that no pollutants are present in the area. Finally, they may recommend necessary repairs or replacement parts if any existing issues are identified. All of these steps taken together ensure that your septic system is functioning optimally and safely for years to come.
