Common Warning Signs that It's Time to Replace a Toilet

Don Jones Plumbing • 4 August 2025

Your toilet is one of the most frequently used fixtures in your home, so it's important that it functions efficiently and reliably. While many toilet problems can be fixed with simple repairs, there comes a point when replacing the unit entirely is the better option. Whether due to age, wear, or inefficiency, knowing when to invest in a new toilet can save you money and stress in the long run. At Don Jones Plumbing, we provide expert toilet repair and replacement in the greater Phoenix area. Here are four signs that it's time to replace your toilet.


Frequent Clogs or Overflows

If your toilet seems to clog more often than it used to, even with normal use, it may be an indication that the toilet’s flushing mechanism is no longer effective. Older toilets, especially those manufactured before modern efficiency standards, often struggle with performance. Constant plunging is not only frustrating but can also suggest that the internal components or drainage design are outdated and in need of replacement.


Cracks in the Porcelain

Small hairline cracks in the tank or bowl might not seem urgent, but they can grow into larger problems. Cracks can cause water leaks, which may damage your flooring or lead to mold and mildew growth. If you notice that the toilet has cracks, it’s often a good idea to be proactive and replace it before a major leak occurs.


Constant Running or Leaking

A toilet that runs continuously or leaks around the base is not just an annoyance—it’s a waste of water and a sign of deeper issues. While some internal parts like flappers and fill valves can be replaced, persistent leaks or recurring issues may mean the toilet has worn out beyond reliable repair. Replacing it can provide peace of mind and reduce your water bill over time.


Inefficient Water Usage

Toilets manufactured before the 1990s often use far more water per flush than newer models. If your toilet uses more than 1.6 gallons per flush, upgrading to a modern high-efficiency toilet can significantly reduce your household’s water consumption. This not only benefits the environment, but also helps lower your utility costs.
