    Not true everywhere. Many buildings, especially industrial, require a flush of the fire suppression system annually or biannually to test that everything is still functional.

      That’s to test the incoming main, the actual grid on the floor doesn’t get flushed. There’s a lot of dead end pipes that can’t be flushed.
