Absolutely it is worth it. I keep seeing this public service announcement on tv where this couple lost two of their three children to carbon monoxide poisoning. I think it is especially necessary if you have an attached garage that you actually put your car in. Better safe than sorry.
It isn't any more stupid than cleanses and diet pills and the such.
If it is your intention to join 1/2 pipe to 15mm copper pipe then use a compression type fitting NOT a solder type fitting, as most people have indiocated, there can be slight differences OR with older type 1/2 copper pipe Quite large differences, so always use compression ( the ones that require an olive, and have to be tightened with a wrench ) Wrap plumbers tape around the olive, and don't overtighten.
C cupped end - the type you would slide over another pipe to make a sweat connection FTG fitting end - the type that slides inside a cupped end, also called a street fitting M male pipe threads FE (sometimes listed as just F, not correct) female pipe threads There are several others, those are just the ones I can think of. The X is by, so C X C is cupped by cupped, a fitting with two ends such as a coupling or elbow, both cupped for sweating onto a pipe or fitting end. C X C X C would be a fitting with three ends such as a tee, all cupped. C X FTG could be a street elbow or a reducing bushing, one part slides over a pipe, the other inside another cupped fitting. C is indeed a cupped fitting. CMP is compression, but there is no such thing as a copper fitting with a compression connection. There are brass and plastic compression fittings that will fit copper pipe, but not copper compression fittings.
