Mark P Posted April 10, 2008 Report Share Posted April 10, 2008 Is every gas appliance suppose to have a dirt leg? Does it make any difference if the gas line comes up through the floor right next to the equipment? Seems there is no need for one on this water heater, but it got me wondering.

Nolan Kienitz Posted April 10, 2008 Report Share Posted April 10, 2008 They are supposed to have a drip leg (as most folks call 'em in Texas). Kind of depends upon AHJ. When I was inspecting the Houston market we called them out all the time and after a year or two the builders started following the rules. I moved to the Dallas area two years ago and I don't think I've seen one up here. I've been told that the gas provided by the utility is dry and due to that there is no need for the drip leg. Ergo ... no one enforces it from what I've seen. I know some HIs call it out, but not very many in this market. I would write up the "spring valve" for replacement to a current style valve.

Bill Kibbel Posted April 10, 2008 Report Share Posted April 10, 2008 Around here it needs to have a sediment trap between the shut-off valve and the appliance inlet ('cept dryers and grills). Link to comment Share on other sites More sharing options...
randynavarro Posted April 10, 2008 Report Share Posted April 10, 2008 I've also learned that its equally important to call the local utility to understand how dirty their gas supply is. And then, each jurisdiction has it's own requirement. Link to comment Share on other sites More sharing options...
RickSab Posted April 11, 2008 Report Share Posted April 11, 2008 Is it normal for copper supply lines in your area. In my part of the woods it's black pipe. Rick Link to comment Share on other sites More sharing options...

Rick Black Iron is by far the most common, but copper is not unheard of. Link to comment Share on other sites More sharing options...
