You can tell when your toilet needs replacing because the water doesn't always flush all the way down or the toilet starts to overflow. If you're not sure whether your toilet needs replacing, you can call a professional to take a look and diagnose any potential problems. Often, simple repairs like fixing a leaky valve can fix the issue and prolong the life of your current toilet. But if it's been a few years since your last repair or if you've noticed other concerning problems, it might be time for a replacement.

There are a few tell-tale signs that your toilet needs to be replaced. If you notice that your toilet is constantly running, or if it's leaking water, then it's time for a new one. You should also replace your toilet if it's more than 20 years old, as they tend to wear down over time. Finally, if you experience any problems flushing or if the bowl is constantly filling up with water, that's another sign that it might be time for a new toilet.
