gas inlet piping

"pull the new poly pipe in with the old pipe"? do you mean making a new hole besides the old inlet to through the new pipe? or enlarge the existing hole for the new pipe?
"electric meters couldn't be installed in that enclosure now"? will this be an issue with the dob inspector even though he was not here to inspect the electric services?

Thats up to the inspector.

I heard the inlet pipe was laid in 1990. the working permit paper should note materials of the piping.
@Mad Dog_2: do you know what type of permit was used back in 1990 for a gas company to lay the gas pipe between the main and the meter?

your words show the steel pipes are more linked to leakages and potential explosions, and plastic pipes are safer, probably thanks to the connections used are more leak proof. black steel pipe is still in compliance with the city fuel gas code. All neighborhood are still using steel pipes except for new buildings.

uncoated black iron rusts through and develops leaks after half a century or so. most utilities started using polyehtylene for services in the 70's.
if there was a permit the city would have it, most cities have their permits online now so you usually can find a copy online through their building department.

@wayneb301 well ,steel pipes last a few decades even uncoated/black ,nevermind zinc coated...
But I do know of polymer/plastic parts in portable gasoline stoves that last much better(almost no fail) in minus 30-40 Celcius conditions while keeping a high power flame going few inches away...
At least polymers don't rust.
But if it does develop a crack for various reasons it will be worse than a small leak from a rusted gas pipe...
Rust develops gradually eats slowly through steel.
You might have time to detect the gas leak in comparison to a crack in plastic/polymer...
Let the science improve things!
Although there is allready a solution rustfree and as strong as black steel pipes: stainless 316L or 304 😁
If price is no worries

hey ,let's be honest : 50 years of no problems in a gas pipe is good enough 😁

in the us most of the gas distribution system is 70+ years old

As far as I'm aware in the US we are only allowed to use polyethylene underground for gas. It cannot be run in buildings, or above ground.
It's my understanding all of the new gas mains are all polyethylene.
That said, polyethylene is far from new. I believe it started being produced in the 1930s and I know polyethylene pipe was being used in the 1950s.
But none of this is helping a guy asking for help with natural gas in NYC where they have very specific rules and codes that must be met.
Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.
