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 tank and water supply first. Confirm the shutoff valve is fully open. Straighten or shorten the flapper chain. Reseat the flapper. Raise the water level to the fill line. Free a stuck float. Tighten the handle nut. Clean mineral buildup in rim/siphon jets. If it still won’t flush, the fill valve or flush valve likely needs service. We handle Toilet Repair and Replacement with upfront pricing and same-day service in Petaluma and Novato.
