Should I replace a deformed copper pipe before pouring concrete?

Fixing a damaged water pipe now is essential because once the concrete is poured over it, access becomes impossible without jackhammering the floor later. Even though finding an urgent plumber is difficult, addressing the issue immediately prevents catastrophic leaks underneath finished concrete in the future.

As this pipe is exposed now, I can see how deformed it is, but after they finish the work tomorrow, it will be impossible to cut and replace it. Is it a big issue? Should I somehow try to find a plumber at 7PM now?source ↗

Seems like someone whacked the crap out of that copper pipe. But in all honesty seems it’s exposed replace now. Don’t want to pour a lot concrete then X amount of years later you’ll have the jack hammered that concrete upsource ↗
