I am just creating the ground works for our plot and we need an access point on the boundary. Problem is one of the flows will come in at 80° to the flow. I think that is called a reflex flow. I have to build the chamber based on existing run, see photo (white mark is chamber center). I was just going to slipper bend and flaunch it in but I could put a shallow bend a few mm back then slipper bend and flaunch it into the flow but this will mean my otherwise dead straight 12m run will no longer be straight. The slipper will turn it probably 45° which is about the angle of a standard plastic chamber. Any thoughts?
