gas appliances

I am also a qualified refirigaration technician and do not know of any refrigeration system with inflammable gas in the system. Sweating on such a system will definately be your last job.

Here's an article from 2009 about the joys of isobutane (R600a) as a refrigerant.

This is a standard 'drop test' and it's not an accurate test. With a large installation there could be hundreds of litres of gas in the pipework and even a small pressure drop over a few minutes could mean a very large leak.

Agreed, although it does perfectly well on the typical domestic installation.

I guess there's a reason why there are different levels of qualification in the gas game too.

I believe the original post related to a "domestic" gas geyser? The main thing is that whoever installs it needs to be a "responsible" person with safety as his main concern. Not securing a gas pipe where it is exposed to friction is not what a "responsible" person would do. My gas pipe goes through a pipe I put in the ground from the kitchen "island" all the way to the outside.
