My Devon m/h was fitted with an automatic gas changeover valve by my supplier. There does not appear to be a makers name on it niether were there any instructions as to use.  I assaumed it would automaticall chang from an empty to a full gas cylinder. However when checking I found it had changed to the full one whilst thother still had about 2 kilo of gas left. This could cause me to run out of gas completely. I hope the attached photo may help someone to identify it for me.   My supplying dealer is unable to assist.     ps how do I attach a picture please?

I never would have both gas bottles open when connected to an auto changeover valve for just the reason you stated.

I always wait until I run out of gas on one cylinder before going to the cylinders and close the valve on the empty one and open the valve on the full one. I always assume that "Automatic" in this context means no tool needed to change from one cylinder's gas to the other. You then can replace the empty cylinder at your convenience.

Of course, that was before, now I have the underslung tank which, while convenient, does not have a "reserve" supply option - just a nasty approximation gauge.

We have one of these which is also unbranded.

Not sure if it works well or not as not been called into action yet. Warning appreciated though thanks.

Thanks. Valve identified as a Gaslow unit. It was mounted upside down by a "reputable" supplier. All now working as should be.

Thanks for the feedback - always useful to someone else.

I would still suggest you follow Dennis' advice. "I always wait until I run out of gas on one cylinder before going to the cylinders and close the valve on the empty one and open the valve on the full one"

That way it's foolproof, and you never run out of gas completely.

Incidentally, I could never see the point of an auto changeover valve, for the above reason. A manual change takes only a second to turn, and you know exactly where you are with one of those.

Perhaps you are right Dave. However, could be worthwhile if you run out of gas just as you start cooking on a dark wet and windy winter evening. Getting togged up, and delving into an awkward outside locker and fiddling with gas valves in the dark doesn't seem too appealing to some of us. Not me anyway! The value of this gadget was proved to me some years ago on our first TA caravan. As usual, it's a personal choice thing.
