Boxing:-) My daughter once had a flat in Shepherds Bush which suffered
from just such pongs. As the elderly leaseholder was reluctant to
bring in professionals, I used expanding foam (fireproof) to close off
the boxing before it entered the flat.

Was there water in the bottom of the pan when the stink was detected?
Some temporary blockages with toilet paper allow the water in the pan
and around the trap to be syphoned out leaving an air passage to the
sewer, and hence the stink. Clearing the blockage and re-filling the
pan/trap with water is the complete cure.

I once worked in a building where one of the toilet blocks was no
longer being used and the water turned off and the door locked.
Within a relatively short period there was a faint unpleasant smell
throughout the building which got worse as the weeks passed. After
much investigation the cause was found to be a absence of water in
the bog traps in this disused toilet.

Vent pipes can *suck* pans dry in very strong winds.


have to be some wind to draw a four inch trap!
did you just make that up ? ....
