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

If your toilet won’t flush and it isn’t clogged, the problem is usually in the tank or water supply. Check these quick fixes first.

• Open the water shutoff valve fully.
• Lift the tank lid: verify the tank refills and the float moves freely.
• Make sure the flapper seals properly; replace if warped or brittle.
• Adjust the chain so it has slight slack and isn’t snagged.
• Tighten or replace a loose handle/arm.
• If the fill valve won’t refill or keeps hissing, it may need replacement. We help homeowners in Appleton and Greenville.
