We are getting those black particles again in our kitchen sink, bathroom sink, toilet and bathtub. We brush our teeth, make coffee, shower with this water. Yuck. Last time this happened, the black particles were in the sink and toilet in the garage as well and other neighbors had it. We were able to get maintenance to come out and flush the pipes when this happened on 12.31.19. We need this again. I have reached out and still waiting for a response from the service team. Please be careful with the water. Attached is a picture from our kitchen sink.
