Hi, I'm a DIY-er who just replaced my 40 year old 30' galvanized gas line with new black pipe. I have a few questions about the process:
1. I saw some people say to not use yellow Teflon. Instead, only use dope, as the Teflon can tear and break appliances. I didn't see this until after I did the re-pipe...I used yellow Teflon and no dope. Is it worth re-doing the whole job with dope only?
2. I did a pressure test and it held. The inspector is coming soon to verify. I cut and capped the old line so there's still about a foot of it connected to the meter. Am I able to disconnect this and connect my new line to the meter myself or do I need the gas company to do this? I haven't been in touch with my gas company since I shutoff the gas myself while I cut and capped the old line. If so, would I use a union to connect the new line? My city says "unions are allowed downstream of appliance shutoff valves, meter locations, and immediately downstream of building shutoff valves."
3. Isn't there a risk of a leaky connection between the meter and new line? The pressure test doesn't cover that one. How do I make sure that final connection is good to go before turning the gas back on?
4. My city says "metallic gas piping is NOT allowed outdoors or within 6 inches of the ground. Exception: Piping with factory coating with approved materials is acceptable for burial in the ground." My black pipe sticks out of my house siding about 6 inches to connect with the meter. What type of paint or spray do I need to use to make this acceptable for outdoors?
Thank you!
