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

If your toilet won’t flush and isn’t clogged, check the tank hardware and water supply first. In Elgin, our plumbers see these quick checks fix most issues.

• Open the tank and confirm there’s enough water.
• Make sure the shutoff valve is fully open.
• Reseat or replace a worn flapper.
• Adjust or reattach a slack or tangled chain.
• Ensure the float moves freely.
• Tighten or replace a loose handle/arm.

If it still won’t flush, we provide same-day repairs and 24/7 emergency service.
