The flapper is a rubber valve at the bottom of the tank that controls the release of water into the bowl. Over time, it can become worn out or misaligned, preventing it from sealing properly.

Fix: Turn off the water supply, remove the flapper, and inspect it for damage. If it’s worn or warped, replace it with a new one, which is inexpensive and easy to find at hardware stores.

The chain connecting the flapper to the flush handle can sometimes be too long or too short. A chain that's too long may get tangled, while a chain that's too short may prevent the flapper from sealing completely.


Fix: Adjust the chain length so it has just enough slack to allow the flapper to close fully.

The float regulates the water level in the tank. If it’s set too high, the water may continuously flow into the overflow tube, causing the toilet to run.


Fix: Adjust the float by bending the rod or turning the adjustment screw, depending on your toilet model, so the water level stops about an inch below the overflow tube.

The fill valve controls the water coming into the tank. If it’s damaged or improperly adjusted, it can cause constant water flow.


Fix: Inspect the valve for wear and replace it if necessary. Adjust it to ensure it shuts off the water once the tank reaches the correct level.
