Appologies in advance for what will probably be a lengthy post:-
First I am looking for advice on building a new soil stack in an extension, it is a 2 storey extension with WC and Basin on the Ground floor and WC, Basin and shower on the 1st Floor. Soil stack goes into a new 110mm soil pipe fitted by the builders underground (BCO Has approved it)
The Builders will be providing a hole in the roof with a 110mm pipe ready installed for venting.
I have designed the extension so that the two rooms are directly above each other and share the internal soil stack.
How do I go about designing/building the stack from scratch and linking the various soil and waste pipes into it, allowing for the correct falls in the pipes and and minimum distances the inlets have to be apart?
