Why does my toilet keep running after flushing?

A constantly running toilet is almost always caused by a faulty flapper valve, a float set too high, or a worn fill valve. Start by checking the flapper — if it does not seal flat against the drain seat, replace it. This is a $5-$10 fix that takes under 10 minutes.

How do I unclog a toilet without a plunger?

Pour one cup of dish soap and hot (not boiling) water into the bowl and wait 15 minutes. The soap lubricates the clog and the heat breaks it down. If that fails, a toilet auger will clear 95% of clogs without a plunger.

TOTO leads for flush performance and longevity. Kohler is best for design variety. American Standard offers the best value under $300. The right brand depends on your rough-in measurement, bowl shape, and budget.
