so the sink drain runs directly to the septic tank. it doesnt connect with any other pipes? many times the slow down occurs where piping join together. Are you getting blockage in any traps or goosenecks? I was able to move kitchen sink gooseneck from the cabinet below the sink to the basement about 36 inches below the sink helping alleviate clogging with increased head. best suggestion is find or make a a clean out in your line and run a snake.
