Oh no! Blocked sewers are a nightmare, we had our main sewer collapse the day we put our old house on the market, that was a very panicked fix to have the house in a state of No Sewage Flowing Down The Driveway before prospective buyers showed up, and incidentally gave me my golden rule of sewer repair men, which is to say, never hire anyone who looks too clean, you want the guy who doesn't mind getting his hands dirty for this job.

I'm glad you've got things back to normal again, but what a saga!
