No gas, full bottle!

[Ingwe]

Well we're on our first outing since wintering in Spain. We filled up with GLP in France in March but haven't used the gas at all until today. We tried to light the gas but although the bottle is full, we get no gas anywhere. We first tried the BBQ point, the. The gas cooker and finally the Truma water heater. Red light-no gas.
It's a Truma monocontrol regulator with an in-line Truma filter. Have tried pushing in the green button on the regulator, letting it out slowly but nothing. Have given the regulator body a gentle tap with a rubber handled long nose pliers but nothing. Any suggestions? Difficult to fry the salmon without it.

Ok I'll be the first to ask. Have you turned on the valve on the top of the bottle, that you turned off when you filled it up.

How do you know it is still full? Could have had a steady small leak over three months and emptied it

it is an Alugas 14kg bottle and has a gauge. The guage shows it as full. But apart from that, if you shake the bottle, in situ, you can hear the LPG sloshing around in the bottle.

If it is a failed Truma regulator, I'll be well pi**ed off as this is the second regulator fitted in a 2012 Bailey, the new regulator being fitted when the Truma filter was fitted not so long ago.
If I need a new regulator, will the replacement ( NOT Truma) connect up to Truma filter?

Yes. I'm one of those who always turns the tank off before filling. I know there are those who say there's no need to but I always have. And I did check (twice) that the tap was turned on

Have you got hoses with the anti blow off thing where you have to push the button on the hose connector to equalise the pressure (and did you press it if yes)?

 

[Compactliner]

you say you've activated the Secumotion regulator button but have you pressed the green button on the regulator-to-bottle hose?
when you do this, the hose sort of jumps as the pressure is allowed through

 

[Compactliner]

snap...

Have you checked the filter is not blocked? The filter has a trap that collects any liquid residue, an oily goo from my experience. If the liquid has built up I can see that it would very quickly block the very fine filter element. You should have got a special tool with the filter for undoing the filter body. If it is very tight you may need to release any trapped pressure to free it.

There is only a green button on the regulator. There isn't a button on the hose/pigtail.

All three of my Secumotions had 2 green buttons, one on the regulator (small button) and and one larger one on the tube itself.

I haven't yet checked the filter. I do have the little spanner supplied with the filter and will have a look at it tomorrow. I haven't got a spare filter with us. But may have a look tomorrow and see if I can clean it.

I had an antiburst valve fail on a pigtail. It failed safe ie closed but meant no gas could get through despite pressing it. I now carry a spare pigtail.

We had the same thing happen to us in the middle of winter while parked up at New Year, stupidly thought for some reason one of the bottles didn’t fill for some reason. Never checked as it was the bottle furthest in the locker. On our return home we found the bottle was full and it was the valve that was stuck.

The 14kg Alugas cylinder is quite tall and if the regulator is below, or level with, the top of the gas bottle the condensates and residues are likely to flow in the wrong direction towards the regulator. They should flow back into the cylinder. The filter housing should intercept these residues but if they are not flowing back into the bottle they could build up.

Our pigtail does not have the green button like the picture posted by Ridgeway.

That extra cutoff valve is optional for a pigtail.
Is it part of a safety pack to “allow” gas on while driving?

I believe so, all 3 i've had came with it. 2 i fitted myself and the last van already came with the same set up, .

Without both buttons you need to turn the gas off when driving. The one on the pigtail protects the high pressure side of the system up to the regulator and the one on the regulator protects the low pressure side beyond the regulator.

 

[Pausim]

On second thoughts I think the modern Alugas cylinders have a built in rupture protection valve so the pigtail one might not be so important. I still choose to have both buttons.

 

[Ingwe]

Just about to check the gas filter (after a really sweltering night). I have the filter removal tool. I've turned off the gas bottle but was wondering whether it is necessary to disconnect the hose from the bottle. I'd rather not as it was tightened by the technician who fitted the filter.

I was just going to suggest undoing the pipe off the bottle and start from the beginning, no difference from tightening any nut.

This is what I was expressly told by the installer of the filter.

You shouldn’t need to remove the pigtail but if there is still some pressure In the system undoing the filter can be more difficult.

 

[Ingwe]

As mentioned above, we don't have the button on the hose connector; only on the Trauma bulkhead regulator itself.

 

[mitzimad]

i think you are going to have to start opening nuts to trace where the stoppage is disconnect bottle and give it a quich spurt then the other end of the pigtail then the outlet of the reg

He could do the quick spurt whilst the filter body is off. If there is gas there then no need to remove the pigtail.

Only the latest ones, our 2014 cylinders don't have them.
