I've just come back from my local Calor centre where I asked about getting my Gaslow/Gasit bottles refilled (not yet obtained and fitted - but I wanted to find out if I could fill up there). They said they would not fill up such a system unless it was a proper automotive installation. They showed me a document which was UKLPG Info sheet 031 - July 2013 (NCC Code of Practice 306 - Motorhomes). This was several pages long and I did not have time to take it all in. I have not been able to find a download for this yet so can't see the details of his arguement. I did say that the system would be fully plumbed in with an external filler point. He said that if the tank could be removed in any way then they would not refill it. Has anyone else tried filling up at a Calor centre (which was closest and cheapest for me)?
