Bog room was stinking at work, turns out there was a blockage but as the
pan itself wasn't backing up there's plainly scope for leakage somewhere
along the pipework under the floor.
I've unblocked it, it's all running freely, the smell has gone.
I can't decide if I can be arsed exploring, there's space issues and
much boxing in.
Just wondering what others would do?
Depends if you are willing to spend a little. What about getting someone
in who has CCTV? That could be pushed along the pipes to see if there is
anything obvious which could have led to the blockage, and might do again.
Sadly (well, not really I suppose) I own the gaff.
While there's no evident problem currently I can't help but be concerned
what's going on beneath.
Someone mentioned cameras, I wonder whether to get one next time they
are in Aldi/Lidl. and shove it up from the manhole end.
Such cameras are not as easy to use as you might think. It could be that
you have a very obvious leak, it might be less obvious. A lot depends on
the geometry and materials of construction. Is this a plastic drain or a
ceramic one. If plastic, is it running underneath your lowest suspended
floor? Hence perhaps leaking on to earth? Or is the building age and
construction such that it would be leaking on to a concrete slab. How
far is it from the loo to the manhole? Is the manhole within or outside
the building? The devil is in the detail.
I don't know where you are but my neighbour runs a speciality drain clearin
g service in East and North Yorkshire called 1-2-Clear. They are geared up
to investigate and sort out such problems. He's recently dealt with a crack
ed underground drain that caused a house to continuously suffer a low level
stink of sewage.
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.
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.
Vent pipes can *suck* pans dry in very strong winds.
