Looks like the guys toilet and tub are below the sewer manhole level in the street. This requires a backwater valve on the building sewer to prevent the public sewer from backing up into a home. But they don't always work. And the hailstones shouldn't be getting into the sewer in the first place, they should have seperate storm sewers that should never back up into the waste system. The stones must have flowed in with water then the water drained back out slowly later. I've worked on a few buildings where entire floors were flooded with sewage from this happening, but never with hailstones. There was another shitty case where sewage overflowed into parking garage storm drain, and the pumps ejected the foul sewage out the curbface during peak lunch hour in front of a nice sidewalk dining area. |
