This past week, Ellicott City, Maryland had one of the worst floods in a long time. You can see some of the devastation that it has caused in thislink. Fortunately, only my basement had a little bit of flooding. But interestingly, this has been the second flooding in over a month. This made me question the drain at the bottom of the walk-down/walk-up basement.
Here is a picture of the drain at the bottom of the stairwell.
