Copper gas line to dryer
Posted by James on March 24, 2002 at 23:40:26:
I have about a 15 foot run of copper tubing that supplies my natural gas cloths dryer in my crawl space. It connects to the black iron pipe and appears to have been added some time ago. It is all above ground and has no sweated joints. It has never been a concern of mine but I'm selling my home and was told that some inspectors might question this. I've seen copper used before for supply of gas to water heaters. Why do some not like copper for gas lines? Does it matter if the copper is L or M?
