I've used it inside a building at least once as well. We ran part of an underground main system through a parking basement to pick up a fire hydrant on top of the podium deck above and pass through the building to dead end at a hydrant on the far side of the property. The AHJ required it, on the assumption that since it was a "private fire main" it should look like one, even if the pipe wasn't buried, which is obviously ridiculous but he was wearing a badge at the time. But let's remember that the thread wasn't about whether you can or can't it was about the reasons it's not commonly undertaken.

But it can be cut-grooved, so it seemed like a logical choice for the below-ground piping. Mark A.
