For the uninitiated, a Saniflo isn't like a standard toilet. It doesn't use gravity to pull waste down a wide pipe. Instead, it uses a macerator—a powerful blade that churns waste into a liquid slurry—and a high-pressure pump to force that slurry through narrow piping (usually 22mm or 32mm) vertically or horizontally to the main soil stack.
The topic is – a genuinely blocked discharge pipe is often fixable with descaling, a wet vac, or careful manual cleaning. However, many online guides skip critical safety steps and confuse air locks, valve failures, or motor issues with simple pipe blockages.
