Effluent Reduction / Home Septic Plant Question / Observation

New home built in 2014 and having problems with the septic plant. I guess it's like a modad but not a modad brand. Anyway. So after dealing with some plumbers and digging up part of my property I run in to the issue causing my home to drain slow. It's where this 40-50' run of black chambered half pipe ends and the standard schedule 40 PVC drain pipe meet at. I call the septic system company that installed it and the lady on the phone says that those effluent reduction things can be replaced after 2 years, they just have to be there to pass code.

Does anyone know if this is true or has done something similar? I'm trying to get an actual technician on the phone to let me know before I go pulling this stuff up and replacing it with a regular tail line to the ditch. I'm kind of amazed that the solution at this point appears to be replacing something with something less costly and from my vantage point more simple.

Thanks baws. Trying to get this thing buried back before the Hurricane gets us all.
