Today's update:
WSSC & plumbing people got their signals crossed; WSSC showed up a few minutes ago, before the plumber could come back and finish the job. WSSC therefore, failed the inspection as "unfinished", and specified what needed to be done to finish. WSSC guy sounded nearly panicked about the impending rain; to be fair, he's right, if it does start raining, anything in the trench is going to come into the house.
Nevertheless, I had to get on the phone to the plumbers and find out where the guy is, and what his timeline is.
He'll call us back when he's on the way.
Rain started at 1320. Didn't last long, nothing filled.
Plumber called back, they'll be here between 1600-1700.
