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, check the tank parts and water supply. Many no‑flush issues come from a closed supply valve, a stuck flapper, a loose chain, or a low water level in the tank. We handle these fixes for homes across Denver and Highlands Ranch.

Quick checks:

• Make sure the shutoff valve under the toilet is fully open.
• Lift the tank lid. Reattach or shorten a slack chain.
• Ensure the flapper seals and moves freely.
• Adjust the float so the water reaches the fill line.
