Silly question may be but when you switch off the gas valve how does it stop the gas coming into your appliances? where does it stop? is there still gas in the down pipe which is next to the meter?
Also I read here http://homerepair.about.com/od/Utility-Shut-Off/ss/How-To-Shut-Off-A-Natural-Gas-Supply-Valve.htm
that only a qualifies person can switch it on again? but when i go on holiday we often switch it off for safety reasons.
