Gas bottles

[The Bishop]

In the van I have a small 907 gas bottle which I guess is sufficient for our needs. It is almost empty but of course can be filled.

In the meantime, in the shed I have a 7kg Calor Gas bottle with a regulator on it that is at least half full. Seems a shame not to use it (although it is too big for permanent use.

My question... If I turn on the regulator I hear the hiss of gas as it connects but then no flow of gas. I would have though I would have a steady flow of gas from the end of the tube or does the regulator do something to cut it off is the gas isn't being burnt? If I push down the little button in the top of the gas bottle gas come out freely. Before I go to the trouble of installing it, do you think my regulator has broken?

Haven t you got anything you can test it on, old camping cooker etc outside with any gas hose.
But to be honest, if your in doubt dont mess about either fill the 907 or buy a new reg, better to be safe than sorry.

Where were you going to put the calor bottle? You know you shouldn't use it if you have to lay it down? I used a 4.5kg bottle for a while and that had to be tilted a bit to fit in the gas cupboard. For £21 quid I'd refill the 907 and keep the calor bottle for using with a gas barbie or something.

The regulator fitted on your cylinder may be an OPSO/UPSO type (Over Pressure Shut Off/ Under Pressure Shut Off) which will automatically turn off the gas if the pressure/flow coming out is too much e.g. a hose that is not connected to anything (its a safety feature incase a hose or pipe is cut or sliced) as previously said try & connect it to a BBQ, Patio Heater etc & see if it works fine when connected.
