Hi there
Is there a way to ensure the absolute safety of your gas bottles? I'm referring to someone being able to turn on the gas bottle taps while your van is parked.

Hi Roy,

There are locks available (here is one)
Just Google LPG cylinder lock to see more.
Cheers

Is that to prevent turning on while you are away from van? because you usually have them, or one at least, is ON while you are parked and the bottles and system is safe. I presume it is a malicious act which you want to prevent!

Yes, it's a case of preventing a malicious act. The second bottle, without the regulator attached is basically open to anyone turning on the valve.

Why not just connect them both to a changeover valve so they are both connected with the spare turned off at the bottle.

Don't you have a screw in plug into the outlet of the spare cylinder. A secure plug should seal any gas escape and only able to b removed by a tool.
I had a Tvan and when travelling both bottles had screwn in plugs to seal gas and to stop ingress of dust and small stones and any debris.

Hello

I have one of these gas shut off valve

If not connected to an appliance the gas flow is cut off even if tap turned on. I think you can get them at Bunnings/BCF

Greg, that is not what Roy is seeking.
The device you referenced is designed to close when there is a "major flow" such as a burst hose. It does not prevent cylinder discharge of moderate flow when a disconnected cylinder valve is partly opened.

Hello

"It does not prevent cylinder discharge of moderate flow when a disconnected cylinder valve is partly opened."

Yes it does (in my case at least) - Ive got one and with no hose attached and cylinder open - gas flow = ZERO (even if you just crack the valve slightly). You have to hold the gauge/button down for gas to come out. As soon as you let that go it shuts off again. With a hose attached you press the gauge down and gauge/hose pressurises, let go and gas will then flow to appliance as required.

Apparently it doesn't detect slow leak in a hose or appliance but opening the valve on the cylinder with no hose attached is obviously above this threshold (proven by real world test by me :) I purchased it for the same reason the OP was chasing - to stop people just turning the cylinder on and walking off. It solves this problem I can assure you (In fact I left gas bottle on by accident after last trip and only just noticed - gas bottle still full as it was - thanks :)

Cheers

Greg, we may be at cross purposes. I believed the product you referenced was the Gasfuse which appears identical and I had the opportunity to inspect a while ago.
With that one, it had no button and required some significant gas flow above normal consumption to cause shutoff. It appears the same as yours. Perhaps it has been upgraded and renamed.
Cheers

No idea what you were basing your comments on - all I know is that the one I provided a link to does not let gas out when the bottle is turned on and nothing attached (i.e. no hose/appliance) (that gasmate one looks identical and I guess it operates the same - I don't know what testing you put it through but appears you didn't do a "no hose test" :) ).

PS The "button" is the gauge - it pushes in, opening the valve - which by default is off. The valve only stays open by itself when sufficient pressure in an attached hose/appliance is achieved. The fact that it doesn't "detect" small leaks (i.e. minor drop in pressure) is another matter not being discussed in this instance.

Cheers

Frankly I don't know Gazz.
I bought a camper trailer with 2 x 4kg gas bottles on the drawbar.
Both bottles themselves are safely secured. However, one of the bottles has a regulator attached but the other bottle is open to whatever. Turn the valve and the gas is free to the elements.
What I was requesting was a way to secure the valve(s).
The first response gave me the answer.

Cheers mate.
It's all new in our household and we're hoping to create a path across the country.
Any corners we can cut will be welcome.
