Can anyone here help me out with designing a wet system for my rainwater tank? Or at least point me in the direction of some info that could help.Essentially I have a rectangular home with 6 downpipes, 4 on the corners and 2 in the middle of the long sides, I understand how the system works from a general point of view, I know I need at least a 500mm drop from gutter height to the top of the tank and trenching and running the pipe should be easy enough but im struggling with working out what size pipe I would need to use and can i get away with not having a first flush diverter if its inky being used for gardening?Thanks for any help via /r/DIY http://ift.tt/2iI7ZBN
