Brown or discolored water is caused by minerals, sediment, or rust that may accumulate in the water mains over time. When the water from your tap is brown this indicates a disturbance in the water main that stirs up these deposits.
If the problem is with both the hot and the cold water, or if only the cold water smells, the problem is more likely with your source water. Iron, copper, and other minerals can cause discoloration in water. To solve these kinds of issues, consider installing a whole house water filter and/or a water softener.
