Drainage for downstairs Toilet

Postby Mattsmith1980 » Mon Sep 27, 2010 10:23 am

I'm fitting a shower room/downstaris toilet underneath the stairs and would really appreciate any advice on the building regs for T-ing into the existing soil pipe.

I've run a new soil pipe underneath the downstairs floor joists and have dug out where the existing soil pipe is (about 18" underground outside the back door) and am looking to put a Y join to join up the new supply. Someone has told me that I need to put a manhole cover here to allow access for rodding. The existing soil pipe runs up the house on the outside. What I was hoping I could do is to put a rodding access connection on this pipe half way up the house, and then just berry the Y bend that will connect the new supply. Does anyone know if this is legal? Any advice would be massively appreciated.

To comply with BRs you need to fit an access chamber where the new pipe joins the existing.
