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

The average US household uses about 3,000 gallons of water per month (roughly 100 gallons per person per day). Indoor use breaks down as: toilet 27%, shower/bath 19%, faucets 16%, laundry 23%, dishwasher 2%, and leaks 12%. A household of 4 with a 1.6 GPF toilet uses roughly 1,500–2,000 gallons per month just on toilet flushing alone.

CCF stands for Centum Cubic Feet — one CCF equals 748 gallons. Most US water utilities bill in CCF or in units of 1,000 gallons. The national average water rate is about $0.005–$0.008 per gallon ($3.75–$6 per CCF). Check your most recent water bill for your exact local rate; it varies significantly by city and region.

Switching from a 1.6 GPF toilet to a 1.28 GPF model saves 0.32 gallons per flush. For a family of 4 flushing 5 times each per day, that’s about 2,336 gallons saved per month — roughly $8–$14/month at average water rates. Over 10 years, that’s $960–$1,680 in savings from a single toilet upgrade, before any rebates.

Yes. Many water utilities offer rebates of $50–$200 for replacing an old toilet with a WaterSense-certified 1.28 GPF model. Search your water utility’s website or the EPA WaterSense rebate finder. In drought-prone areas like California, Arizona, and Texas, rebates can be especially generous — sometimes covering the full cost of a basic efficient toilet.
