Safety first
Lift only the tank lid if it is light and easy to handle. Set it on a folded towel.
Written steps
- Make sure the flush handle is not stuck in the down position.
- Carefully lift the tank lid and look for a chain caught under the rubber flapper.
- If the chain is tangled, gently free it without bending or disconnecting parts.
- Confirm the flapper lies flat after the tank fills, then replace the lid.
- Submit a maintenance request if running continues.
Stop and request maintenance if
- The toilet is overflowing, leaking at the floor, or rocking.
- The shutoff valve is corroded or hard to turn.
- A part appears broken or disconnected.
