Replacing some old and laying some new stretches of underground foul drainage. In one place, I have to remove an inspection chamber as this is where foundations for the extension are going. The inspection chamber is obviously a point of change in direction, I'm guessing about 95-100degrees (slightly over right angle). I intend to replace this inspection chamber with rodding eyes slightly further up the end of the straight runs.
Whats the best way of linking up my over right angled run? a 45 and an adjustable bed set to about 50?
Ideally no bends at all, but whats the max for a 110mm drain on a run?
