Hi all
I'm putting in an en-suite 4.5m away from the main stack in my bungalow and am not sure if i have enough fall before the main soil stack bends and dissapears to the horizontal plane. I initially thought i did and have cut the main soil pipe part way through the 90deg bend.
My plan was to put in a Marley 67.5 Degree Offset Bend at this cut off as this would enable me to make the turn tighter than the current 90deg one in place and thus give me the extra fall. Well i think i might have over estimated the fall available - i was hoping for 10cm.
So, i have noticed that there is a drain pipe going into the drainage system just outside the house where the ensuite will be. I have checked by pouring water into this and i can hear it come out into the same drain by listening down the open end of the main stack. I was wondering if i might be able to tap into this underground pipe on the other side of the u gully trap or does this go against the builing regs incase of overflow etc.
Anyone else any ideas?? Other than knocking the whole thing on the head and washing and toileting in a bucket for the forseeable future...
