Symptoms
- Handle feels loose or spins with no resistance
- Pressing the handle produces no flush
- Chain visible dangling inside the tank
- Flapper doesn't move when the handle is pressed
Likely causes
- CommonChain unhooked from the flapper or handle armThe small chain connecting the two parts has slipped off one end.
- PossibleBroken or snapped lift armThe plastic or metal arm inside the tank has cracked and can no longer transmit motion.
- PossibleStripped handle mounting nutIf the nut holding the handle has stripped, the handle spins without engaging anything.
What to do
- Remove the tank lid and look at how the chain connects the handle arm to the flapper.
- Reattach the chain hook to the flapper's tab, leaving a small amount of slack.
- If the lift arm itself is broken, replace the whole handle and arm assembly, which is inexpensive and simple to swap.
- Check the mounting nut behind the handle (reverse-threaded, tighten counterclockwise) if the handle spins freely.
- Test with a few flushes to confirm the flapper lifts fully and reseats each time.
Tools and parts
- Adjustable wrench or pliers
