OUR IGEM EXPERTS ANSWER YOUR COMMON TECHNICAL QUESTIONS themselves as ‘black dust’ or flakes.
The behaviour described is fairly
typical and can occur in isolated
instances where one property
experiences the problem, but
neighbouring properties may be free
of the problem.
However, deposits in the meter
are more unusual and may require
further investigation.
As a quick check, you could see if
the particles are magnetic by doing the
following: sprinkle the particles on a
sheet of white paper and then move a
magnet underneath the paper. If the
particles move with the magnet, then
they are magnetic. Magnetic particles
generally means that they contain iron
and this is not usually from the copper
pipe sulphidation process.
Of course there is a chance that the
particles have dropped back into the
meter from the copper piping on the
