What is a Saniflo Macerator?

A Saniflo macerator is a plumbing device designed to pump wastewater from a toilet and other bathroom fixtures to the main sewage line. It works by macerating, or breaking down, solid waste into a fine slurry that can be easily pumped through small-diameter pipes.

Key Components

  • Macerating Unit: Grinds up waste.
  • Pump: Moves the waste slurry to the sewage line.
  • Non-Return Valve: Prevents backflow into the unit.
  • Ventilation System: Ensures the unit operates efficiently without creating odors.
