Is it ok to have a common drain to the street for both my deck drain and my downspouts from the roof?
It would be a main 4” PVC pipe to the street, with 4 roof downspouts and the deck drain feeding it.
I think it’s probably a 1-2 foot elevation drop from the first downspout to the street. All the other downspouts and the deck are roughly the same elevation.
I wasn’t sure if this is a typical practice, or if the preference is to have separate drains for the deck vs roof downspouts. Would there be a chance the roof downspouts would actually hydraulically back into the deck drain in very heavy rain?
