Follow your nose
We started to notice some, well, issues in the morning with some pretty yucky water backing up into our laundry tubs. I of course immediately figured "oh great, just what we need, a super expensive problem that will likely require us calling some plumber dude who walks around with his ass hanging out his pants, digging up the front yard and replacing all the pipe in the house, and writing him a big fat cheque with lots of zeroes before the decimal point on it while he touched everything in the house so I would be unable to keep a mental list of what he had touched and would be slowly driven insane trying to remember what items I had to soak in bleach and scour until my hands were raw to prevent certain e.coli and cauliform contamination from his sewage-ey hands."
Luckily, in a fit of reasonableness I called the region and they sent two nice (if somewhat gruff) dudes to clear the sewer line from our house out to the main line today. They sent their thingy down the pipe in our basement, cleared the tree root that was apparently obstructing it at no cost, and were on their (unmerry?) way, leaving us to marinate in the bleach fumes from our near toxic-levels use of it in the basement. Dave did most of the primary (read really gross) cleanup and I'll likely do the neurotic level one tomorrow to finish things off. We figured we'd let it pickle overnight for good measure. I'd pick the smell of bleach anyday over sewage though. It's practically a comforting smell at this point.
And, I'm really glad I'm not these dudes. Man that'd suck.
