What is a Macerating Pump?

A macerating pump is a compact plumbing system that allows a toilet, and often a sink or shower, to be installed where traditional gravity drainage isn’t possible. It works by grinding waste into a fine slurry and pumping it upward through small-diameter piping to your home’s existing sewer or drain line. This makes macerating pumps an ideal solution for basement bathrooms and other below grade spaces—without cutting concrete or major remodeling.
