Yes repair bots. But a record of them. These pipes have a bunch of sensors. How much flow. What capacity. Breakage. Pressure. So it links to all these countries with the stations. There would be a record of the bot in the pipe. It gets detected.

It's not hard but explain explain.

No, it was damaged outside. They wouldn't have suggested it. Or there's also the possibility of bad pipework. That's kinda bullshit. New pipes. But not impossible.
