I don't know if I blogged this earlier, but I am replacing my sewer. This was an unforeseen part of the new garage project. My old sewer line ran directly under the garage, and would not survive the pouring of the new, heavier-duty concrete pad. So we hired a plumber to move the line. I hope he'll be finished with it today.
The original line is 78-year-old terra cotta – I'm surprised it's lasted as long as it has.
