Got the water level down to merely "wet" except at the floor drain -- which has valved itself off until the storm/sewer drains return to normal. A pretty steady trickle of water still entering at all the cracks in the floor, of course.
Had to tape up cracked spots in the sump pump hose; and it's full-manual, so I can't just leave it running.
Were I rich--! But I'm not.
