Downspout Drain Pipe Routing
I need to connect piping (e.g. black corrugated) to one of my downspouts to channel rain water away from a mulch bed and to the side yard. Problem is I don't have very much slope to work with, so about the first 1/3rd of the pipe will be exposed if I go with 1/4" per foot. This isn't too big of a deal because there will be shrubs concealing some of it, but the first 5' to 6' section will be visible. If I were to instead bury the entire run and have no slope at all for most of the run aside from the beginning and end, would this be a big deal? This would allow me to bury more of the pipe near the downspout. If I go this route, about an inch of rainwater would collect and sit inside the pipe at all times (unless it didn't rain for a while and dried out), but anything in excess of that would drain out the end come the next rainfall. I can't think of any reasons this would be an issue (maybe it would invite bugs/mosquitos?). Another idea, although probably not legal, is to discharge into a plumbing cleanout, which is less than 2' from the downspout. I imagine the sewage company wouldn't be happy about this, but it sure would be convenient. Figured I'd ask. Come to think of it, I guess that would allow sewer gases out huh? That wouldn't be good.

So having a successful drain requires proper slope.
The real problem will come in the winter, if the pipe is above ground any water in there will freeze, if there is any flat spots with the pipe shallow buried then that will freeze also.
