I have an oil storage tank for CH, which is in the way of a wall I
intend to build. I intend to move the tank by buying a new doubled
skin variety, siting it with all the pipes etc and then transferring
at a suitable moment. How can I transfer the oil in the old tank to
the new? They will be about 10m apart. I have googled for various
types of pump, but they all seem to be permanent solutions and I only
want a one off
