Water heaters can last a fairly long time if you take proper care of them, but they aren’t invincible. Sooner or later, the wear and tear of years of normal use will cause the water heater to break down permanently. What’s important is that you be able to recognize when your water heater is nearing the end of its life, so that you can replace it before it dies completely. Let’s take a look at some of the signs that you need to replace your water heater.
The older a water heater gets, the more various parts of the system will start to wear down. This will cause a drop in output that only gets more pronounced over time. Of course, any water heater will temporarily run out of hot water if you put enough demand on it for a long enough period of time. That’s not what this is, though. If your water heater can’t even meet a moderate level of demand for a short time, like for a quick shower, then you should probably replace it.
You really shouldn’t need to repair your water heater more than once every few years. They’re designed to withstand quite a bit of stress, and as long as you schedule preventive maintenance once a year yours should hold up pretty well. The closer a water heater gets to the end of its lifespan, though, the more the wear and tear on the various parts of the system will cause parts to start failing. If you need to repair your water heater multiple times a year, especially if it’s a different part each time, you need to install a new system.
