Our basement has a sub pump and it’s never once kicked on in 3 years. We got new gutters and downspouts before we moved in and have not had a single flooding problem.

As a fun side note, there was a hole in the side of our home from someone stealing the coal shoot door. We had to have that bricked up… but the previous owner literally did not give a single solitary fuck. Soooo that could have been some of the water too.
