With new extension I need to connect soil pipe into existing underground pipe and I'd need a new inspection chamber where it connects (change of direction). I want to minimise the number of bends which would potentially mean that the IC would be within 1metre of the existing footings of the old house (the edge of the IC would be approx 650mm from the footing). Would this be okay if I concrete it in as per Document H section 2.25? The bottom of the IC would be approx 200mm lower than the footing.
Thanks
