Zoomup:
I thought that the bayonet type gas connectors were self sealing. Isn't a blanking plug as bad as socket covers?
Nearly. All that the valve needs to do when an appliance is removed is to prevent most of the gas escaping for a short while. A blanking plug would be like having an appliance connected, which would be long-term.
It's a bit like the valves on your car tyres. They provide a temporary seal whilst you adjust the pressure, but what keeps the air in is the dust cap. That is why I prefer metal ones, although I did have a problem recently with corrosion of the valve stems. ?
