terra cotta underground pipes
My home is a three story end of group townhouse that was built in 1915. It also has a gable roof.
I have a downspout that empties into an underground terracotta pipe that is nonfunctioning. Does anyone know how these pipes were installed? For example, where do they normally lead to -- my sewerline made of the same material that lies even deeper below? or simply into the yard somewhere? If so, how far into the yard and how deep into the ground do they run?
What materials do you suggest to replace this pipe? I cannot run piping over ground because it has to cross where a sidewalk and cement steps leading to the basement exists.
