I have a wall mounted gas heater where the gas is supplied via (bare) copper pipe buried in the floor screed. Eventually the floor will be tiled, thus rendering the pipe inaccessible. So, while I am doing the rest of the kitchen I want to take the opportunity to terminate the gas supply prior to the point at which it enters the concrete.
How can I do it? Close valves to and from gas meter. Fit earthing jumper across inlet and outlet pipes. Remove gas meter. Cut gas pipe at convenient point. Seal cut end - but with what? I wondered about a Compression Fan Key Gas Cock on the basis that once I have re-installed the gas meter I can open the tap to purge the gas/air mixture.
When my gas hob is intalled I will expect the fitter to make a proper (?) connection for the hob.
TIA
