Does anyone have any idea why the propane gas stops flowing into my van when the bottle gets down to about 1/3 full? I've replaced pig tails and Truma regulator!! It gets expensive wasting 1/3 bottle every time!!!

May I ask how you are determining they are 1/3 full? I see no gauges in the photos.

Hi Pauism, yes you can hear the liquid gas swishing around.

I have no cure for your problem to suggest but can put forward a relatively simple work around. If you acquire a refillable gas bottle there is no need to wait until it is empty to refill at the likes of a Morrisons PFS.

Of course somebody more technically minded than me may have a solution for you.

Hi Pauism, yes you can hear the liquid gas swishing around.
You do seem to have a strange problem.

I am no expert but was told the top of the bottle should be well below the level of the regulator, so that condensates in the pipe drain back into the bottle. From the pictures it looks like your bottle is at about the same level as the regulator and that there is a low point in the pipe coming from the bottle. I am not saying this is the cause of your problem but it might be worth checking. Perhaps the pipe gets blocked with condensate but when you change bottles it hangs down and drains. When disconnected the pressure would drop in the pipe perhaps allowing the condensates to rapidly evaporate.

They are not GasIT refillables as there is no inlet port. Looks like standard Calor or Flogas. We had a similar problem with flow in our last van before we fitted GasIT. The regulator needs to be well above the exit point from the cylinder or it will oil up. We had to change the regulator twice in 4-5 years. We then used the smaller bottles and the problem disappeared. Difficult to see how you can lift your though. :-(

A shorter pipe without such a pronounced low point and a filter to intercept the condensates might help but shorter bottles are probably needed.

Alternatively, a hook or two on the side wall to hold the hose so that there is a gentle upward run all the way from cylinder connection to the regulator. The stick on hooks should be man enough.

The OP's opening post says he has replaced the regulator.

Thanks everyone for taking the time to reply đź‘Ť
I will down size to 6kg when the next bottle needs changing and see if the height below the regulator makes a difference.
