Black tank pipe size
I have a new RV and noted that the pipe from the black tank is small (2 inch I think) while the gray tank is 3 inches in diameter. Aren't these reversed. I checked to make sure it was not just the handles that were reversed but the smaller pipe is definetly from the black tank. Aren't there some code standards for this plumbing? Won't this make it harder to adequatley empty the black tank?
