Toilet Flapper Valve Failure
The toilet flapper has warped, cracked, or lost its seal, causing continuous water flow from tank to bowl. This results in constant running water, higher water bills, and potential mineral buildup in the toilet bowl. If ignored, it wastes significant water and can lead to staining or mineral deposits that become harder to clean.
DIY Feasibility
Simple replacement requiring only basic tools and available at any hardware store.
Verify for Yourself
Listen for continuous water running in the toilet tank, or lift the flapper by hand to see if it's warped, cracked, or doesn't sit flat against the flush valve seat.
What to do right now
- 1Turn off water supply valve behind toilet to stop continuous running
- 2Remove tank lid and push flapper down firmly against seat to temporarily stop flow
- 3Check if chain length is correct - should have slight slack when flapper is closed
These are interim steps to slow or contain the issue while you arrange a proper repair.
