Why is my toilet always running?

Why Is My Toilet Constantly Running?

A constantly running toilet typically indicates an issue with the components inside the tank. The most common causes include:

• ✔ Faulty flapper valve: The rubber flapper at the bottom of the tank may be worn, warped, or improperly seated, allowing water to continuously leak into the bowl.
• ✔ Incorrect float height: If the float is set too high, water will continuously flow into the overflow tube. If it's too low, the tank may not fill completely.
• ✔ Damaged fill valve: The mechanism that controls water flow into the tank may be worn out or contain debris, preventing it from shutting off completely.
• ✔ Corroded flush valve chain: A chain that's too long or too short can prevent the flapper from sealing properly.
• ✔ Cracked overflow tube: Cracks in this component can cause water to leak continuously.
• ✔ Mineral buildup: Calcium and other mineral deposits can prevent components from sealing properly.

A running toilet isn't just annoying—it can waste hundreds of gallons of water daily, significantly increasing your water bill. Most running toilet issues can be fixed by replacing the flapper or adjusting the float, which are relatively simple repairs.
