It rained heavily yesterday evening and overnight. I went to bed with storms and woke up at five a.m. to loud thunder and lighting -- and the sounds of a deluge. Went down to the basement a few minutes ago on a hunch, and there's a good-sized puddle of clear water on the floor. Clear is a good sign -- it means it came in along the foundation.
Looks like there may be an inch of water at the lowest point, which is the drain, and which probably means the backflow valve in the floor drain has closed. Yes, we still have combined sanitary and storm sewers, and if too much ran falls too quickly, it can back up. The next-highest drain is the laundry sink, two feet or more above floor level, with the top of the sink at maybe a yard above the floor and after that, well, I hope I won't find out.
The backflow has a little history of sticking, so the next step will be to put on boots and apply a plunger. I'll probably wait a while -- the rain has ended, but only just, and there's still water running to the storm drains.
Drain-worrying times like these remind me that they make "soaping valves" for showers. It's more often seen in regions that are short on water, a little sliding valve that goes between the supply pipe and the showerhead so you can shut off the water, lather up and scrub without changing the settings for temperature and amount. If I ever have the washroom redone (I'd love to but it's expensive), that's something I should add.
