Recently I have noticed that my water has a faint yellowish brownish tint to it, I only noticed it because I compared the color after it froze in ice trays to water I know is clean in another tray (clear cubes compared to a yellowish tint to them) I have drank the water, before I noticed the discoloration, but I haven't gotten sick or anything, but why is it discolored? Should I just let my land lord know, and have her worry about it?
