My bungalow doesn't have a toilet vent. Other identical properties in the area do.
The position where the vent could have been is now a drain for the basin and bath, with the other properties don't seem to have.
Curious as to whether something wrong has been done in past modifications. The people before the folk we bought from were Italians and seemed to have done a few things like taking away purlin supports and opening up a room without consideration as to what was above it.
Thoughts?
