All my drains and toilet stopped up so I knew something was wrong with the main leading to the septic. After calling local plumbers who either didn't call back or didn't want to do the job I needed help right away. Roto-Rooter promised they would be out later in the day and they were. I was told the cost up front, what could be the problem and best case/worst case outcome. Fortunately the drain was cleared. It's not cheap but well worth the cost for someone to come out and do an unpleasant job cheerfully and professionally.
