A flush toilet (also known as a flushing toilet, water closet (WC) – see also toilet names) is a toilet that disposes of human waste (principally urine and feces) by using the force of water to flush it through a drainpipe to another location for treatment, either nearby or at a communal facility, thus maintaining a separation between humans and their waste. Flush toilets can be designed for sitting (in which case they are also called "Western" toilets) or for squatting, in the case of squat toilets. Most modern sewage treatment systems are also designed to process specially designed toilet paper. The opposite of a flush toilet is a dry toilet, which uses no water for flushing.
Flush toilets are a type of plumbing fixture and usually incorporate an "S", "U", "J", or "P" shaped bend called a trap that causes water to collect in the toilet bowl to hold the waste and act as a seal against noxious sewer gases. Most flush toilets are connected to a sewerage system that conveys waste to a sewage treatment plant; where this is not available, a septic tank or composting system may be used. When a toilet is flushed, the wastewater flows into a septic tank, or is conveyed to a treatment plant.Associated devices are urinals, which dispose of male urine, and bidets, which use water to cleanse the anus, perineum, and genitals after using the toilet.

    How can I remove this flush valve?

The cistern water level is nowhere near the overflow pipe, so I suspect there's a faulty seal at the bottom of the flush valve (a Geberit model). However, I am unable to detach the flush unit to check. There don't seem to be any side clips to...
