Toilets

Toilet won't flush at all

When pressing the handle does nothing, the connection between the handle and the flapper has usually come apart, rather than a clog or water supply issue.

Symptoms

  • Handle moves but nothing happens in the bowl
  • No water sound when pressing the handle
  • Flapper doesn't lift
  • Handle feels loose or floppy

Likely causes

  • CommonChain disconnected from the flapper or handle armThe chain linking the handle to the flapper has come unhooked.
  • CommonBroken lift arm or handle assemblyA cracked or snapped handle mechanism can't lift the flapper anymore.
  • PossibleFlapper stuck to the valve seatMineral buildup or age can glue the flapper down so it doesn't lift even when pulled.
  • PossibleLow or no water in the tankWithout enough water, the flush mechanism works but produces no visible flush.

What to do

  1. Remove the tank lid and check the water level; if it's very low or empty, that's the real issue (see the tank-won't-refill guide).
  2. Press the handle while watching inside the tank to see if the flapper lifts.
  3. Reconnect the chain to both the flapper and the handle arm if it's come loose, leaving slight slack.
  4. Gently wiggle the flapper by hand to free it if it seems stuck to the seat.
  5. Inspect the handle and lift arm for cracks or breaks, and replace the assembly if damaged.
  6. Flush by hand once (lifting the flapper directly) to confirm the rest of the system works while you fix the handle.

When to call a pro

A plumber is rarely needed unless the internal tank fittings themselves are broken or corroded beyond a simple parts swap.
