Gas Valve Location

Hi,
Sorry but this might seem a stupid question but we have just had our habitation service done and everything was working well. But we are just about to leave for France for a couple of weeks and I can't seem to get any gas through. I have a refillable tank which shows three quarter full, I have checked the three valves in the wardrobe but the fridge wont work on gas and thee is no gas coming through the hob rings.
As said the habitation service was only done last week but I wonder if they might have turned off some isolating valve, if so where is it? the only valves I have used in the 2 years of ownership are the three in the wardrobe. Would really appreciate it if someone could let me know if there is an isolating valve somewhere, its dark but I have searched high and low to no avail and of course Marquis are closed now!!
Many thanks in anticipation.
John.

There will be a regulator underneath after pipework leaves the tank. Also on the tank itself there is a turn wheel valve. This is underneath the central plate on the cylinder itself. Either of these may have been turned off.

A similar thing happened to us last year, immediately after the  habitation service.  I insisted that they come to me to fix it and I expected it to be the fact that they had not turned the gas back on.  When the engineer investigated he said that a particular safety cut out  had been activated on the tank and he disconnected the tank to reset it. It was a quick and, I think, simple operation.   He said that he thought that the gas would have been turned off for the habitation service but had been turned back on again too quickly (by the habitation engineer.)  According to him,  doing so, fools the system into thinking there has been a sudden collision so it shuts down as it is meant to do.
Yours may not be the same problem but the symptons are the same.

Hi Paulmold, Ploughlin and Merv,
Thank you so much for your incredibly quick response, very much appreciated.
With the help of your kind advice and a torch, I located a "gate type" valve on the bulk tank and under a cover. This was turned off!  I am sure this must have been an oversight after the habitation test was completed, anyway after turning it on the gas flowed and cooker etc was working. However, the fridge still did not function on gas when put on the auto setting. Bizarrely, it will work when on the gas setting but not on auto.
Thanks again for your input all I have to do now is to remember to switch over manually. I can get the problem sorted when we get home but at least we can enjoy our 2 weeks in Brittany|!
What a great group this is.

As regards the Channel Tunnel there have been lots of previous discussions on this. AS themselves say you only need to turn off at the manifold (they even put such info in their handbooks) and lots of members will confirm that they have never turned off at the tank.

OK, it must have been an oversight last year when the van returned post habitation check with all appliances working.
I don't use the tunnel but ferry seems happy with wardrobe Valves off. The under van valve is not very accessible and partly covered.

One lesson from my experience with the gas supply after habitation service is that in future,  I will check that it's on at the tank before driving away from the dealer's.

Two reasons why we use the services of a mobile engineer for our habitation check.
1. You are witness to how the inspection is carried out to your satisfaction.
2. It's far less expensive at £115.

I shall be using the one you recommended next year.
