The long running story which started with John Morphet telling us that the gas bottle stands were fitted with switch over values - when one bottle emptied the value switched automatically to the second value!
Does anybody have this solution ?
was this another of John Morphet's good intentions !

I had some interesting if at times confusing discussions with Limefitt about gas bottles.
The policy now is that all lodges not on mains gas should have two gas bottles. When I queried if my regulator would switch automatically when one bottle was empty I was told it would not.
However Trevor Morely (may his name forever be revered now that he has been banished to Fallbarrow) found out for me today that in fact it will.
Here's how it works:
There is a manual switch on the top of the bottles which points to
one or the other bottle.
Bottle # 1 is used until it is about 25% full at which point the
regulator starts to draw off bottle # 2 as well.
When bottle # 1 is empty an indicator on the bottle (or regulator I'm
not quite sure which yet) goes red. This tells you that bottle # 1
needs to be changed. Theoretically bottle #2 is now about 75% full,
When Bottle #1 is replaced you point the switch at bottle # 2 and the process begins again.
