Recently, when I turn on my shower in the morning, the water runs clear for a few minutes, then a spurt of black inky water comes out for anywhere from two to 10 seconds, then it starts running clear again. I haven't noticed this with any of my other faucets/water sources. What might be causing that black water (I assume something's collecting in the pipes somewhere) and is it something I should be worried about? As a side note, my hard, hard water does seem to eat through my plumbing like it was made of spun sugar.
