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

Start with quick checks in the tank. Most no‑clog flush failures come from the handle, chain, flapper, water level, or the shutoff valve. If parts are worn or the valve won’t refill, we can repair the toilet and inspect same day.

Quick checks:

• Open the tank and untangle or shorten the chain.
• Reseat or replace the flapper if it’s warped.
• Confirm the shutoff valve is fully open.
• Adjust the float so water fills to the marked line.
• Clear rim/siphon jets with a brush.
• Replace a noisy or sticking fill valve.
