I went to Home depot today and the salesman said that I need to buy the green pipe(scotch pipe) for underground gas pipe installation. He said I cannot use the ordinary black pipe for outdoor underground gas line installation. The "the green pipe" is more expensive and for my 100 ft instllation it is considerable. Please comment. |
