Strange. I just posted a reply about an hour ago and it's gone. I guess glitches happen.
Repost but a shorter story. I may have given the impression that I was being aggressive in my response above, but my matter-of-fact tone may not have translated well over text. I was, in fact, very calm but maybe a little too quick to the point and I apologize for not being more clear.
Recent events with a close friend of mine has solidified my reasoning for not giving gas advice on the forums and recommending a professional instead. He did some work with internet advice and though most of the work was great, some very important stuff was missed and created a very dangerous situation.
For me to outline my thoughts on PTFE and thread sealants would be contrary to what I have already stated. It would seem to others that I condone the use of it by DIYers by explaining how it should be used. I feel that there are too many pieces to the puzzle of gas line installation to safely advise on it, but these are just my opinions and anybody else can help if they choose.
I'm not hating on DIYers, I'm a huge fan of helping friends and family as well as strangers on the forums. I just think that there should be a line drawn on certain subjects. When a person asks a question like Kimspetcare did, you have to question how knowledgeable and experienced she/he is with gas lines and how safe could the installation be without even knowing the basics of 'pipe dope'.
Safety is always a concern with every trade, but with gas there's the surprising element of "BOOM, JUST BLEW UP A WHOLE FREAKIN' HOUSE!!" Y'know what I mean? So, I'm not hatin' on anybody. I think that a very cavalier attitude is given towards gas line repairs...even 'basic' repairs...and not enough respect towards the power of what natural gas can do.
