What are the signs of a hot water tank going bad?

There are several common signs that your hot water tank may stop working. Consider calling a water heater services company to take a look at and repair or replace your unit if: 

1. Your unit is getting old. The average water heater will last 8 to 10 years. 
2. Your water smells or is discoloured. For example, if the water looks rusty the unit may be corroding. 
3. You hear loud noises coming from your hot water heater. Loud popping or crackling sounds can mean sediment has built up in the tank.
4. Your tank is leaking or you notice water around the water heater.
5. Your hot water tank no longer provides enough hot water.
6. The water pressure has gone down and is not sufficient.
