I didn’t have gutters on the backside of my house. That was the point where my roof angles joined and created a water slide which shot the rainwater off my roof, especially during our heavy Florida rain storms. In order to use your rain chains I need to slow the water down first. So, I added a large copper bucket to your design, hung it from a strong bracket, cut a 3" hole in the bottom and then hung your rain chain from that. The rain chain directs the water into a basin covered with rock.
