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.

What is the best toilet brand in 2026?

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.

What is rough-in measurement for a toilet?

Rough-in is the distance from the wall behind your toilet to the center of the floor drain bolt holes. Standard US rough-in is 12 inches. Buying the wrong rough-in size is the number one installation mistake homeowners make.

Frequently Asked Questions

TOTO consistently ranks as the most reliable toilet brand, with industry-leading flush technology (Tornado Flush) and a CeFiONtect glaze that resists mold and mineral buildup. Kohler is the strongest US-made option for value and parts availability. For proven budget reliability, American Standard’s Champion 4 has an outstanding track record across millions of installations.

Two-piece toilets have a separate tank and bowl — easier to ship, less expensive, and simpler to repair since individual parts are widely available. One-piece toilets are sleeker, easier to clean (no gap between tank and bowl), and slightly less prone to leaking at the tank-to-bowl joint. For most bathrooms, a quality two-piece is the practical choice; one-piece is worth the premium in master bathrooms.

GPF (Gallons Per Flush) directly impacts water use and your water bill. The sweet spot for most households is 1.28 GPF — it meets EPA WaterSense standards while maintaining strong flushing performance. Going below 1.0 GPF is viable only with high-end pressure-assist or tornado-flush technology; cheaper low-flow models may require double-flushing, eliminating the water savings.

A longer warranty reflects manufacturer confidence in the product, but the terms matter as much as the length. TOTO and Kohler offer lifetime limited warranties on their porcelain — but “limited” often means the warranty excludes labor costs and has conditions around proper installation. Always read what’s actually covered. For most buyers, a 5-year warranty on a quality toilet is more valuable than a “lifetime” warranty with many exclusions.
