I noticed within the last day or two that the water in my toilets were dirty. I flushed them a couple of times but the water is still not clear. I also ran the water in my bathtub and the water that was in there was also dirty. It did not look rusty but just dirty. I have already called my city public works to come out and check the line coming from the outside into the house to see if there is a problem. Does anyone know what could be causing this?
