Excellent work. They look very good indeed and it's satisfying to get the detail right.

Excellent detail. If you have a stench pipe, should you not have a lavatory outlet leading into it?

 

(Terrible how putting in an exceptional level of detail only prompts requests for more. Sorry.)

... and if we are going to be really pedantic , the 'stench' pipe, or soil and vent pipe to give it its proper name, would be a larger diameter than the rwp's, the former normally being 4" diam in old money and the latter 3". Great modeling none the less. Keep up the good work.

Well, if the toilets were internal then the pipes  might go directly under the floor to be connected to a common soil. The stench (vent) could be at the end of the run furthest from the sewer trap. If the soil branched then there would be vents at the end of each of the branches.  

Hi Alan, Killybegs and Dave.

 

Looking at the photographs I couldn't see any evidence of any junctions on the stench pipe. The pipe might be a larger diameter than the down pipe but I'm not entirely convinced.

 

Keep safe everyone.

They do look the same. Since it is just a vent it could well be a smaller diameter than the soil. A building I have been involved with ( built 1862) has nominally 3" vents but an 8" soil. 

 

That really is an elegant building, if I were a rich man ....... 

The vent pipe would be installed as near as possible to the head of the drain run. If there were no bathroom or toilet in the vicinity then there would be no connection to the vent.

Dave - vent pipes, most commonly 4" round cast iron, quite often have no branch or other connections.  They were connected into the last (highest) manhole on the system to prevent back pressure (siphon) in the underground drain so no gulley or grating at the foot.
