I moved into my first "old" house last year and had a question about the storm sewer lines. The downspouts were already disconnected from the round cast iron pipes around the perimeter of the house which I'm assuming were part of the old storm sewer system that is no longer (or shouldn't be) used.
The pipes are open, with no caps. Should they be capped off? If so, what would you use to cap them off? My local hardware store wasn't much of a help part-wise.
