I am thinking of moving shortly into a 1950's house that has a downstairs toilet at the front. The house is not nearby so I can't go and look at it easily, but I have photos.
From when I looked around the house, and from the photos, there appears to be no soil stack venting at all - the only pipework I can see is drainpipes and sink etc pipes down an outside drain.
It is a semi-detached house, but it is not sharing a stack with next door either.
How is it being vented? I am also interested in locating it (or something) because I would want to add another toilet upstairs, if I move there.
