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

If your toilet won’t flush and the bowl isn’t clogged, the problem is likely in the tank or water supply. Try these quick checks before you call.

• Make sure the shutoff valve is fully open.
• Lift the tank lid; untangle or adjust the flapper chain.
• Check the flapper for a tight seal and smooth lift.
• Set the float so water reaches the fill line.
• Listen for the fill valve; replace if it won’t fill or runs nonstop.
