Built to last, here is what actually needs attention
The porcelain bowl lasts decades, often 50 or more years. The tank parts inside, the flapper and fill valve, wear out about every 5 years.
Because this one is built to last, the useful section for you is not a lifespan chart, it is the maintenance list below.
The fill valve and supply line are cheap parts that fail, and a burst toilet supply line is a classic overnight flood.
Overview
A toilet is really two products in one. The porcelain lasts practically forever, and the working parts inside the tank wear out on a much shorter cycle. Once you know that, maintenance is mostly about the tank.
The maintenance that buys you the years
- Replace the flapperHigh impactEvery 4 to 5 years
A worn flapper is the number one cause of silent leaks that quietly run up the water bill.
- Replace the fill valveHigh impactEvery 5 to 7 years
A failing fill valve causes constant running or slow refills.
- Test for silent leaksHigh impactYearly
Put a few drops of food coloring in the tank. If it shows in the bowl in 15 minutes without flushing, the flapper is leaking.
- Check the supply line and shutoffMedium impactYearly
The braided line and the angle stop age, and a burst line is a big water damage event.
- Reseat with a new wax ring if it ever rocksMedium impactAs needed
A rocking toilet breaks the seal, which leaks under the floor.
Signs it is failing
- The tank refills on its own without a flush (a running toilet)
- A slow or weak flush
- Water on the floor at the base
- The bowl loses water level between flushes
- Rocking or feeling loose
Repair or replace
Almost everything in a toilet is repairable. Replace the whole unit only if the porcelain is cracked or you want a higher-efficiency model.
