    • though the higher the pressure, the faster the water-steam mix will move because more of it will expand into vapor bubbles. Cavitation is also bad for the pipe itself because, when the bubbles do eventually collapse, the force of the implosion can erode the walls of the pipe and lead to structural failure.
