Where Does The Waste Go From A Saniflo Toilet «Certified – WALKTHROUGH»

A Saniflo toilet, however, operates on a completely different principle. Because it’s often installed below the main sewer line or far from an existing soil stack, gravity alone won’t cut it. Instead, the flush triggers a hidden unit behind the wall or inside a cabinet: the macerator.

In the world of modern plumbing, few inventions have sparked as much curiosity—and confusion—as the Saniflo toilet. Tucked into basements, attic conversions, loft apartments, and garage workshops, these compact macerating toilets promise a bathroom anywhere there’s water and electricity. But for every homeowner who installs one, the same uneasy question eventually surfaces: After I flush, where does it all go? where does the waste go from a saniflo toilet

This pumping action is the real “magic.” Without it, you could never install a toilet in a converted cellar or an island kitchen. But it’s also why Saniflo systems require electrical power: no electricity, no flush. So where does the pressurized slurry go? It doesn’t exit to a special “Saniflo-only” sewer. Instead, the small pipe snakes through walls, floors, or ceilings until it connects to a standard 3- or 4-inch vertical soil stack—the same stack used by your regular toilets, sinks, and showers. That connection is made via a special non-return valve (to prevent backflow) and a sealed fitting. A Saniflo toilet, however, operates on a completely
