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

If the toilet won’t flush and the bowl isn’t clogged, the issue is likely in the tank parts or the water supply. Advanced Plumbing & Rooter Service provides same-day toilet repairs in Oakland and across the Tri-Valley.

Quick checks:

• Open the water shutoff valve fully.
• Lift the lid: untangle or shorten the flapper chain.
• Check the flapper seal; replace if warped.
• Raise water level to the tank’s fill line.
• Tighten or replace a loose handle/lever.
