After an extended trip away from home, the water coming out of your faucet could be slightly discolored—luckily, the discoloration usually goes away on its own in less than a minute. But what if this happens to your water regularly? Is the discolored water dangerous to your health? Can you use it to cook, bathe, or clean? Often the water is safe to use, and can often be associated with an aging water heater, rusty pipes or the need for water treatment to remove commonly found contaminants and/or unwanted components such as hardness and iron.
