In blocks of flats, is it normal for all the toilets to share a single soil stack / SVP?
So if there is a blockage in the lower part of the SVP, what is to stop the sewage backing up and overflowing from a lower flat's toilet?
All the sewage from the flats above would keep flowing down and the lower flat toilet would act as an 'overflow'.
I can't find anything regarding this when searching online.
Surely it would be sensible to have one SVP per flat? That way, there is no pressure of sewage downfall from flats above.
Many thanks.
