Clue #1: Age. The older the water heater, the more likely it is to break down. As a general rule, a tank type water heater will last, on average 8 to 12 years. With proper maintenance and a little luck, you may be able to nearly double the lifespan of your water heater. But sometimes even with the best care, a water heater will need to be replaced after only a few years.
If you turn on the hot water and see brown, then the anode rod in the water heater needs to be replaced or the entire water heater itself may be malfunctioning (water heaters have a lifespan of roughly 10-15 years).
