Thats what I thought too. Anyway, this does not apply to water only,
so I guess I can put in any angle I like. But I'll be prepared for the
BCO to shout at me !

Coming in late but puzzled. You can only put in an angle accomodated by
the inspection chamber socket and or the gulley outlet. So why not create
the gradient to suit the inspection chamber socket by a short bend and pipe
extension at the gully. Or am I missing something?
