Downpipe branches are used to bring together two downpipes. Usually this would be a rainwater pipe from a low section of roof, such as a porch, connecting into the main drop from the roof gutter.The branch is angled at 112 degrees which is the same angle as an offset bend, ensuring that the two connecting pipes are perfectly aligned where they meet.Connections are a simple push fit joint - this is to enable the branch connection to be taken apart for cleaning as required.
