Good step by step diagnosis of a major break in sewage pipe and blokage. Several solutions. I didn't like the first solution from inside so went w alternative quote that worked out well. Job was accepted in evening and everything started to happen within an hour w PECO and permit. Crew was very professional and experts at their part of the job.
