Hi all, I’m after some advise on connecting into my neighbours manhole with a new drain line from a WC I’m adding to the front of my house in a porch. The problem with doing this is the position which it will enter the manhole is the opposite side to the direction of flow from the neighbours ( See picture.The red arrow indicates the existing direction of flow, the green is the position from where I intend to enter from my property). I want to know if it is at all do-able, or will it cause problems to the existing direction of flow, and if so what would be the best way to do it. There is plenty of fall for my pipe as this manhole is a metre down so would I be best to use a drop drain into it from say half way down or is it best to enter from right down at the bottom. I hope I’ve explained this well enough. Thanks in advance.
