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

If your toilet won’t flush and there’s no clog, check the water supply and the tank hardware first. Many issues are quick fixes you can do safely.

• Verify the shutoff valve is fully open.
• Lift the lid and confirm the chain lifts the flapper freely.
• Adjust the float so water reaches the fill line.
• Tighten a loose handle nut.
• If the fill valve won’t refill, schedule service.

We repair and replace toilet parts across Denver and Aurora. Ask about $50 off work performed on toilets.
