Which brings us to the second reason to give the insulated tanks a
There are in place, mechanisms for disposing of small amounts of
asbestos. Sensibly, they are there to encourage proper disposal.
Sadly, in some cases, they seem to have been manipulated by people
who know the regulations, but only present to the public a version
that results in maximum profit for themselves.
I am referring to the practise, by some, of telling people they
cannot accept asbestos, however well protected, that is transported
in private vehicles, but they are happy to come and pick up for a
considerable fee. If you fall for this deceit, you may well pay for
your tank 8 times over. The typical boot load price quoted is around
$75 if you pack and transport.
The quote below from "Confederaterebel" is good advice
>>>asbestos is easily removed if one knows how to. if asbestos iskept wet there
will be no dust. dust mask, gloves, and cheap paper suits can be
removing the stuff.<<<
If you really MUST deal with this material, here is a further
suggestion or nine.
Before you do anything else, fill the space between inner and outer
tank with water until it overflows from the highest spot.
Allow the water to drain away through some holes drilled very close
to the bottom.
Use a SMALL wheel on your angle grinder and make 6 equi-spaced
vertical cuts top to bottom on the steel jacket.
Remove the screws holding the top plate of the outer jacket.
Remove from the work area all electrical tools and leave only the
hand tools required to finish the job.
Have eight or so TOUGH garden clean-up bags ready
Set up a temporary sprinkler rose over the work area.
Strip to your skivvies keeping some old shoes on.
With the sprinkler running, you can now remove the top plate, bend
or walk down the 6 steel "petals" and start loading the bags. When
PART filled, start another bag. Do not overfill. These critters will
be heavy. Meticulous clean-up is the order of the day. Remember,
anything that you don't collect into the bags, will dry into fluff
and be blowing around your property. When done, tie off your bags
and then double bag them.
Finally, a good shower under the sprinkler without your skivvies,
wave to the neighbours to let them know you appreciate their
interest, throw away those old skivvies and you're done.
You have been warned,

> of Australia.Hello Wal,
You are correct that there is copper corrosion in Australia. It
seems to occur in a few percent of properties over a wide area. This
is also a problem in Europe and North America.
It appears as though all the reasons for the corrosion are not fully
understood, and various scientific bodies are still doing some
fairly intensive research.
Based on the percentage of properties that experience copper
corrosion, the chance of getting a dud tank at random is in roughly
the same order.
If the acquisition is confined to uninsulated tanks, a heavily
corroded tank will be fairly obvious, and the odds will swing in
Removal of the 2" BSP blanking plug will let you see inside with a
pen torch. This should make it a near certainty that your are buying
a tank you can use.
