7 Signs You Need a Water Heater Replacement
Quick answer: Age over 8 to 12 years, rust, leaks, loud noises and lukewarm water are the biggest signs. A leak from the tank itself means replace it.

A water heater works hard every day. At some point, repair stops making sense. Here are seven signs it is time to replace it.

1. It is old Tank heaters often last 8 to 12 years. Check the date on the label.

2. Rust-colored hot water Rust in hot water can mean the tank is corroding inside.

3. Water around the tank A puddle from the tank body usually means it has failed. A leak from a valve or pipe can often be repaired.

4. Loud popping or rumbling Hard water leaves sediment at the bottom. A flush can help. If noise stays, the tank may be near the end.

5. Lukewarm water or running out fast A bad heating element or thermostat can be fixed. If the tank is old, replacement may be wiser. See water heater repair.

6. Higher energy bills Sediment makes the heater work harder.

7. Many repairs in a short time If you keep paying for fixes, a new unit can be the better choice.
