Even propane is odorized with mercaptan, hence the sulfur odor.

As for the yellow plastic line, it is likely low or medium density polyethylene. More and more the poly-pipe is being used by natural gas distribution companies. It's a huge industry now. Nothing wrong with it for low pressure systems.

In some applications we use poly tubing for instrument or analytical gas...at a lot higher pressure than you see in your house.

I have a gas license, and copper pipe is o/k provided it's the proper thickness. Personally I don't like using it.

first you did a fine job. if you really don't trust yourself, use avation gasket sealant-good to 125psi. the box of nipples in 1/4" increments is called a run. a union is the way to complete the job, but your gonna end up short.

PBH - i don't see a single staple on any of that wiring.

Copper is not recommended in the Western US because of the presence of sulfur. It's OK if the gas doesn't have the sulfur, but how can you be sure? Also, the statements about O2 and H2O are correct, both work on the copper. And, the type of solder used is important. However, silver solder and copper should last many years wherever installed.

I know here in Missouri copper is a no no for natural gas. I was told by more then 1 plumber to use a brand of pipe dope by the name of RectorSeal. You can buy it Home Depot!

The staples were pulled out while I installed my downdraft range hood. The wires will be re-stapled before the ceiling tiles are re-installed.

In Ontario you can use copper, however you can't use soldered fittings. The copper comes in a roll. The end fittings are flared.

I would not use copper. The gas you use on the east may be different than ours on the west but you never know what you will have in the future. We use yellow pipe in all our gas distribution installations, I think up to 6 or 8 inch, our pressure in the gas lines is about 45 psi, and house ine pressure is about 12 inches of water column or a 1/3 of a pound. As souk said pipe dope is good for your fittings. Use palmolive soap with some water to test for leaks.

I'm not a big fan of using copper. I don't mind cutting and threading pipe. There is a flexible pipe that is coated with yellow plastic that is good for concealed areas that regular gas pipe would be difficult to feed through, however I can't think of the name of it.

Not true. If you have a current insurance policy and blow up your home because of faulty DIY work, you are covered. If you maliciously/intentionally make that mistake in order to burn down your house to collect insurance $$$, you will not be paid (and then, only if proven).

If a "no DIY" clause was written into homeowner's policies, Home Depot, Lowe's & Maynards would be out of business and plumbers/electricians/contractors would be more expensive than doctors.

Will your insurance company drop you/raise rates afterward? Most likely. But doing un-permitted, unlicensed & shoddy work yourself is not grounds for denial of a claim.

That being said, I've never seen copper used for natural gas in a residential situation, and I've lived on both coasts. And, if you don't know EXACTLY what you're doing, natural gas is deadly in more ways than one...suffocation and explosion.

The job is done. He used copper and did a nice job.

The deck it goes up to is being replaced in the next couple of years. At that point the copper will be replaced with black pipe.
