I just recently bought an approx. 80 yr old colonial style home. It has openings for two drainpipes (one at the back corner and one at the front corner of the house, but the downspouts have been diverted not to flow into them. I want to reconnect the downspouts to the drainpipes, but (1) Iím not sure where the water will flow because I do not see any opening at the street, and (2) I don't know if they even work anymore. Can someone please point me in the right direction?
I would not recommend these be reconnected.
In most cases these pipes ran into the drain lines from the house into the sewer system. Many municipalities mandate these are not allowed to be connected.
Besides .... it's not uncommon the pipes that run down into the house can be cracked or broken causing problems you didn't bargain for.
In my opinion leave them disconnected from the outside downpipes and seal up those openings.
