Hi Prof. Thanks for the reply with which I agree wholeheartedly. Safety is paramount. However, the Safefill cylinder is fitted with a shut-off valve so that the cylinder is not overfilled. The connectors used to fill are identical to those used on a vehicle lpg modification, otherwise filling would be impossible. As the filling process is 'sealed' there is less chance of fumes escaping than when filling up at a petrol or diesel pump on a conventional vehicle.
All processes when followed correctly are fool-proof but unfortunately not idiot-proof.
We recently camped near Ashbourne and a caravan arrived one evening and I noticed two Calorlites in the front locker. Next morning these were replaced with a single Gaslow cylinder. Being nosey I sauntered over and we chatted. Seems that this was a new van and the owner had just ordered a Gaslow extension kit to replace the one he had left installed in his old van. I do not know nor did I ask about his experience and competence with regard to fitting the extension kit. I believe qualifications are required to carry this out. I may be wrong.
At least with the Safefill it can be swapped between vans and is a one-off cost. Nor does it involve any extra connections which Gaslow does i.e. the extension pipe from cylinder to side panel filling point.
One minor point is that some filling stations are not equipped to take car and caravan particularly on the continent. I have had to unhitch the van and leave my wife on guard duty while I fill the car a few times but this is obviously not the norm. One can leave the van on site and take the Safefill with you when it needs filling.
These points are of course my own opinion but I am very happy with my Safefill for all the reasons I have stated. It is also subject to 10 year testing. Things can go wrong as with the Calorlite recall but that's another story.
Regards, Mike.
