Most people don’t give a second thought to their water heater, and this appliance can run for quite a few years, typically from ten to about fifteen years or so, and give a steady supply of hot water on demand. Eventually the hot water heater will have to be replaced, however, and there are a few things to start looking for if your hot water heater is long in the teeth. If you start to see what looks like dirty water or rusty water coming out of your hot water tap, you probably have a system that has developed rust inside. If the amount of hot water being delivered to sinks and showers seems lower than it was previously, you might want to call a technician to look at your unit. So those are some signs to pay attention to if you are wondering how soon it will be to change your water heater.
