I've searched this site and all over the shop, but can't seem to find out if the thing I want to do is unusual or wrong. In planning the first floor bathroom and ensuites etc, I need to discharge two WCs into the soil stack. Question - is the correct way to do this via a double equal branch (which Plumbase sell but the geezer on the phone said they didn't sell many!) into the stack, or two stacks, or some off-set separate connections, which would seem to bring challenging arrangements for correct falls etc?!
Any help much appreciated
