Toilet Cannot flush

    1. Check for clogs – use a plunger to clear obstructions in trapway. Snaking may be required for major clog.
    2. Examine chain/handle assembly – adjusted too loose or disconnected can prevent flapper from lifting.
    3. Inspect flapper valve – cracked, warped, or misaligned valve allows water to leak from tank to bowl.
    4. Clean debris around flush valve seat – prevents flapper from sealing tightly. Scrub with brush or rag.
    5. Check fill valve – if not shutting off completely will reduce flush power. Adjust float height or replace.
    6. Ensure sufficient tank water level – should be 1″ below overflow tube. Add water if too low.
    7. Clear obstructions from siphon jet hole – maintains siphoning during flush. Use straightened wire hook.
    8. Remove toilet and inspect trapway and drain passage in floor flange for major blockage.
    9. Replace worn tank components like flapper, handle, fill valve if toilet still won’t flush properly.
    10. Call a plumber for drain line video inspection if troubleshooting does not resolve issue.
