Скачать или смотреть Black Gunk in Water from Bathroom Faucet

HOW I SOLVED IT:
It was the hose that led from the floor to the faucet. It is steel mesh on the outside and black rubber on the inside. The rubber was breaking down; and when there was a lot of force, that black, greasy rubber would come out in the water. All I had to do was replace that hose. Didn't even need a plumber. Not sure if that solution could apply to a tub. Good luck!

Thank you, Abraham Farrar, for suggesting the comment update. (You were the only one to enlighten me after many years of this video being up.)

ORIGINAL DESCRIPTION (when I first posted the video):
Here's what happens when I run the cold water full blast in my bathroom. What the heck do you think is going on here? This doesn't happen out of any other faucet in the house. The black gunk is greasy, chunky, and a little tacky.
