Hey guys, I cannot find where my gutters and 2 garage floor drains discharge too! We are on a well and septic system and I have confirmed 100% that they do NOT drain into the septic. I did this by oppositely running the shower and running a hose in the gutters, while listening to my septic with the lid off. Shower, clearly yes; gutters, clearly no. I can trace it all the way around my house to a white vertical vent pipe which goes under a backroom towards the septic, but not into. Is there a standard dry well design homes use? Thats the only thing I can think of. I haven't been able to find an outlet hose anywhere on our property. Thank you in advance!
