On a site a few yeas ago, the houses where about 5-10 years old in 1996, so they must have been built after we changed over from town gas to natural gas.
I went to do a job and found the whole copper installation pipework internally coated with a hard black flaking substance.
It looked like the oxidisation you get when you anneal copper, but obviously wasn't.
Apparently its sulphur affecting the copper. Some UK gas fields especially Morecombe Bay are said to have a large sulphur content.
The result was a complete pipe out.
Anybody found the same problem anywhere?
