To stop a toilet from running continuously, follow these steps to identify and fix the common causes:
1. Adjust the Float Level
- Inside the tank, there is a float that controls the water intake. If the float is set too high, water will overflow into the overflow tube and keep running.
- Adjust the float lower by turning the adjustment screw or bending the float arm down, depending on your toilet model, so the water stops about an inch below the top of the overflow tube
2. Check and Replace the Flapper
- The flapper is a rubber valve at the bottom of the tank that seals water inside.
- If it is worn, warped, or dirty, it won't seal properly, causing water to leak into the bowl.
- Inspect the flapper for damage and replace it if necessary. Also, adjust the chain length so the flapper closes fully without being too tight or too loose
3. Inspect the Fill Valve
- The fill valve controls water flow into the tank after flushing.
- If faulty, it may not shut off water properly, causing continuous running.
- You may need to replace the fill valve if adjusting the float and flapper doesn't stop the running
4. Temporary Fix: Shut Off Water Supply
- If you want to stop the running immediately and cannot fix it right away, turn off the water supply valve located behind the toilet. This stops water flow but disables flushing until repaired
By carefully adjusting the float, ensuring the flapper seals properly, and replacing worn parts like the fill valve or flapper, you can stop your toilet from running and prevent water waste
. If these steps do not resolve the issue, consider consulting a professional plumber.
