The porcelain body of a toilet can last for decades, often 25 years or more, if it is not cracked or damaged. The moving parts inside the tank, like the flapper and fill valve, wear out much sooner and usually need replacing every five to ten years.
Parts That Wear Out First
- Flapper: the rubber seal at the bottom of the tank hardens and warps.
- Fill valve: the part that refills the tank can stick or leak.
- Flush handle and chain: these can loosen or break.
- Wax ring: the seal under the toilet can fail, especially if the toilet rocks.
- Supply line: the hose that feeds the tank can crack or leak.
Signs It May Be Time to Replace the Whole Toilet
Sometimes it makes more sense to replace the toilet than to keep fixing it. Consider a new toilet if:
- The bowl or tank is cracked
- It clogs often even with normal use
- You are replacing parts several times a year
- It uses much more water than newer models
- Parts are hard to find for an older design
Why Newer Toilets Can Help
Many older toilets use far more water per flush than newer models. Today’s water-saving toilets are designed to flush well while using less water. Some newer designs also have wider passageways that clog less often. Look for models with a WaterSense label if saving water is a goal.
Making a Toilet Last
Flush only toilet paper, fix running toilets quickly, and avoid harsh tablet cleaners in the tank, which can damage rubber parts. Do not stand on the toilet seat or lid. Check the base and supply line every few months for drips, and tighten nothing so hard that the porcelain cracks.
If your toilet keeps running, leaking, or clogging, fixing or swapping out a worn toilet can stop the cycle. To compare models for your bathroom, you can get recommendations from a plumber at (833) 603-1840.
