I own a home somewhere between 70-100 years old. In the cellar is a pit, about 3 feet deep, which contains a floor drain and the sewer drain caps for access to the traps.
After heavy rains and flooding, for the first time in 6 months of owning the house, I passed through the basement and heard running water. Coming from the side of the pit, right by the floor drain, was a steady and strong flow of water into the floor drain. It doesn't seem to be coming from a pipe, but from the concrete of the pit (actually, a hole in the concrete).
I'm glad it's going into the pit and down the drain, and I have one of the driest cellars in town. But after heavy rains I never saw this happen before. It seems a drainage system would have connected tot he pipes rather than spilling through a hole into the pit.
Does anyone know if this is by design in old homes, or is this some kind of freakish drainage and possibly erosion?
