Looks like my valve is faulty as it will not fully isolate both bottles. It is almost isolating both bottles but not fully.
Its not important as you can isolate the gas bottles anyway but suggests the valve is not to good anyway.

I wonder at the "real" need for a swap over valve... A T is all that is required and the gas is controlled by turning the bottle valves on or off... Unless of course you run to an Auto changeover Valve..
Hi TT,
I reckon that you are now on the minimalist side of things.
It would be necessary with just a tee connecting two bottles to turn the gas of on the full bottle. And that is what you are trying to prevent. How else can you remove the empty one for a refill? When you undo the bottle you have an open end of a full bore pipe.
Or am I missing some thing and having a senior moment?
In an auto system the whole governor system changes to the full bottle sensing the pressure drop of the empty bottle. The pointer is merely set to point at the full bottle and nothing has lost its flame and all appliances are still working.The empty can be taken away with no pressure drop.
With a manual system you actually can run out as soon as the bottle is empty, then change to the full bottle.The pointer going to the full bottle (being a tap) , then isolates the empty bottle for removal.
I now have to note that I cannot accept owners ship, truth, quality, or veracity, of articles I may quote off the internet.
