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

If your toilet won’t flush but isn’t clogged, check the tank parts and water supply. Most no‑flush issues come from a stuck flapper, a loose chain, a misadjusted float, low tank water, or a closed shutoff valve. Summers Plumbing Heating & Cooling serves Dayton and nearby cities with same-day help.

Quick checks:

• Lift the tank lid and verify the water level is near the fill line.
• Make sure the handle lever and chain move freely.
• Ensure the flapper seals and isn’t warped.
• Confirm the shutoff valve at the wall is fully open.
