A failing water heater usually gives warning before it fully quits. Catching these signs early means a scheduled fix instead of an emergency.
Rust-colored hot water, especially if it clears after running for a bit, often points to corrosion starting inside the tank itself.
Sediment buildup causing noise doesn't fix itself and tends to get louder as the buildup grows — see our full guide on popping and rumbling noises for more detail.
Any moisture around the bottom of the tank is worth taking seriously — it can mean a small fitting leak that's fixable, or it can mean the tank itself is starting to fail from the inside.
A heating element or burner that's struggling often shows up first as hot water that doesn't last as long as it used to, or temperature that swings during a shower.
Most tank water heaters last around 8 to 12 years. Age alone isn't proof of failure, but it raises the odds that any of the above symptoms mean replacement rather than repair.
Catching a failing water heater early means you can schedule a repair or replacement on your terms, instead of waking up to a flooded closet or a cold shower. See the emergency water heater repair page, or call (888) 616-9423 for a diagnosis.
Real human, real truck if you need one.
