Hi
Currently building a new ground floor cloaks with WC and basin - drain run is in, connected and approved by BCO - internally all there is is the end of the 110mm pipe
I want to connect a WC and a basin to this pipe - what's the best way? so far I'm considering a) building a "mini internal stack" with durgo, using a branch "on it's back" and connecting the basin on the vertical, finishing witha durgo; and b) plumbing WC straight to the existing 110mm pipe and "strapping" on the basin waste direct to the 110mm with an anti-vac fitting to preserve the basin trap...
Is either of these the best thing to do? or something else I haven't thought of?
TIA
Jim
