The answer to 'when to replace toilet' is that you should replace your toilet when it is no longer functioning properly or is too old and outdated. Toilets typically last 10-15 years with regular use and maintenance, but factors like water quality, frequency of use, and any damage can impact their lifespan. Signs it's time to replace your toilet include frequent clogs, leaks, cracks, or if it's using too much water per flush.
Replacing an old, inefficient toilet can also save you money on your water bills and be better for the environment. Modern, high-efficiency toilets use 1.28 gallons per flush or less, compared to older models that can use up to 3.5 gallons. Upgrading to a newer, WaterSense-certified toilet can reduce your household's water consumption by thousands of gallons per year.
