How do you clean out a septic system drain field?
To clean out a septic system drain field, start by having the septic tank inspected and pumped. Once it has been inspected, locate the drain field and use a roto-rake or other mechanical device to break up and loosen the soil. Then use an air compressor and airknife to blow out any debris that may be clogging the pipes. Finally, use a backhoe or other digging machinery to remove the old soil and replace it with fresh soil.
