### Decoding Toilet Flush Malfunctions

Modern dual-flush cisterns save water by offering 3-liter and 6-liter flush options, but their internal mechanisms require periodic calibration.

- **Weak Flush That Doesn't Clear the Bowl:** Often caused by an improperly adjusted fill valve setting the water level too low in the tank, or mineral buildup blocking the rim jet holes around the bowl. - **Hissing Sound Long After Flushing:** The fill valve is not shutting off cleanly, allowing water to continuously bleed into the overflow pipe. - **Water Seeping on Floor Around Toilet Base:** The wax ring gasket sealing the commode horn to the drain flange has failed, allowing wastewater to seep under tiles whenever flushed.
