110mm foul waste pipe

[terrye]

hi all
i'm a new member
fitting a w.c. into loft,soil pipe will be 10 mts approx in length and connect to a stub stack at outside ground level.
The stub stack is vented about 3 metres away by a cast iron 4" pipe approx 20 feet high and well above the roof
will this be ok as regards to building regs re the 6 metre soil pipe rule?? or will this need further venting?
many thanks for any replies

I t will be alright. Just wack a durgo on the end by the toilet. Some manufacturers have different lengths of runs for toilet wastes. Think terrain is one

forgot to say there will be 4 bends and 4 mts of the 10 metre length will consist of 2 lots of verticle drops. i will be putting in 2 access points
