True.. Same around here, and the local council run tip has 100's of the
things too. The latter are a bunch of Nazi's though, claim to be into
recycling and yet NOTHING can leave the tip via the public! Used to be
different when privately managed.
But yes as others have stated here the thread is RH and tapered, and
I recently had to remove one myself to "recycle" the cylinder and
convert into a vacuum tank for my vac former.
Unfortunately, they only seem to have the big cylinders. When I've
needed the cylinders for their intended purpose, I've need the
pumpkin-sized ones, and have unfortunately had to pay the deposit for them.
I've undone a couple of the valves on the cylinders used in portable
gas fires - they were a right hand thread. I wanted to purge them
just as you do to use them as low pressure air reservoirs. I don't
know about the large red propane cylinders.
Hope this helps, Toby
