What should I do if my toilet won't flush but is not clogged?

A toilet that won’t flush but isn’t clogged usually points to a tank fill or flush mechanism issue, not a blockage. The most common cause is the handle linkage failing to lift the parts inside long enough to release a full flush. A quick technician tip: a brief tap on the handle can mimic failure—hold it down for a full second during a test.

Check these quick items before calling a plumber:

• Lift the lid: water should sit about 1 inch below the overflow tube; open the shutoff if it’s low.
• Inspect the chain: it needs slight slack; untangle or reclip if tight or off.
• Look at the flapper: reseat it; replace if warped or waterlogged.
• Check the float/fill valve: raise the float if low; no refill suggests the valve needs service.
