A water pipe was clogged due to calcium accumulation
You want to avoid limescale in your water pipe, as it can eventually lead to clogging issues and may slow down your water supply. Minor calcium buildup can be treated by dissolving it with acids, but more serious cases require a stronger solution.
Look at how thick that limescale is. That calcium accumulation looks like a rolled mattress, though not exactly a comfortable or clean one. Hopefully, this person used the photo to warn people about this problem.
