Why is the water in my hot water heater rusty?
Rust-colored hot water can be caused by bacteria growth, pipe corrosion, tank water heater corrosion, or mineral deposits in the water supply. If the cause is due to aging plumbing, replacing those pipes or appliances could fix the issue. Let’s explore a few reasons why you might see yucky, rusty water.
Can rusty water come from water heater?

How do you fix rusty hot water?
One solution for the rusty hot water, excluding hard conditions such as a rusty tank, is to drain and flush the tank thoroughly through the drain valve. If the heater tank and plumbing system are infected with the bacteria, shock therapy with the chlorine, followed by flushing, should be applied.
Can the inside of a hot water heater rust?
Hot water heaters have an anode rod inside of them. This rod is designed to draw in corrosion and rust in the water, helping to protect the tank itself from rust. But, as it sits in the tank, it can break down and begin to rust or corrode. When this happens, you wind up with rust in your heated water.
