|In response to Re: teflon tape on black iron gas pipe|
It is immaterial if you cannot get it to hold pressure and cannot find the leak, then you may have to disassemble and redo it anyway. I do not subscribe to using teflon tape on steel pipe threads since a friend did a large gas system and had to redo it because of multiple leaks.
: : I had a gas line and meter installed and put together a gas distribution system. Unfortunately, I cannot get it to pressurize. It slowly leaks down in spite of all the soapy water on all the joints that show no discernible leaks. I have been told that it is because I used the wrong type of teflon tape - the white stuff which is gas permeable rather than the yellow "gas" stuff. I was also told that my installation would be rejected by the inspector anyway because of the use of the "wrong type of tape" and that I should tear the whole system apart and either use the yellow gas tape or, use a gas approved dope. Is this correct or is this Eagle Hardware fantasy?
