Well I haven't heard of the other couplings either. The only difference I knew of was plumbing pipe has taper threads to seal and electric rigid conduit have running threads. The reasoning about not using galvanized pipe was that the inside coating can flake off and clog orifices etc. The digging tools keep clean and sharp. I scrape off the dirt then sandpaper and coat with used oil when I store mine. A little shapening on the cutting edges using a file or grinder help a log also.

Well looks like I got the problem fixed. I didn't have to dig as far as I thought since the pipe was in good condition. I initially wanted to replace the pipe from the meter all the way down to the 90 but a friend told me it wasn't necessary to do this. When all was said and done, 30 inches of pipe was replaced. Now for some questions. What is the difference between the types of coupling that are used? My friend told me I had an api (a p I) coupling. Then another friend told me the coupling I was trying to use is a merchant coupling. I thought a coupling is a coupling, didn't know there were several types. Second, I've heard from several people who say do *not* use galvanized pipe for gas, but I've heard from just as many saying they use it all the time with no problems. The gas technician who originally came out says that the code says you can use galvanized. So what's the story on this? Third, for future reference are there any tips you have for digging? My parents lent me a shovel and it got the job done, but it was extremely slow. Felt like I was digging through concrete, not dirt. It's only a matter of time before I'll have to dig again (sewer lines this time). It's just a matter of when (hopefully no time soon). Shane [Non-text portions of this message have been removed]
