My gas hob...

is now legal.  We had the plumber out to look at the boiler, as we thought we might need a new one.  We didn't, but I asked the question, "could he connect the Propane supply to my cooker", when he saw how it was connected he went apoplectic,  for years the gas my  hob has been supplied by a small propane bottle in the shed, and the connection has been a flexible hose, totally illegal.

I now have a proper connection, copper piping, with the legal fittings, and what a difference it makes to my hob, I now have constant pressure.
