I'm about to get a new free-standing range cooker delivered, that's going in
place of the existing hob / oven combination. I would like to have it
removable from its space. Are flexible rubber gas supply pipes with a
detachable bayonet fitting still ok for this sort of thing ? If so, I will
insist that the gas-fitter puts one on, as I seem to recall that in the
past, they were frowned on a bit by the 'pros', although I did have that
arrangement on a cooker at a previous house, and it never caused any
problems over a number of years' service.
