Macerator Pumps

Macerator pumps are designed to pump solids-laden wastewater such as raw sewage through smaller-diameter pipe lines. This is achieved by breaking up the solid items prior to pumping. A macerator toilet, macerator pump and lifting station can be installed below the sewer level, to allow you to install a cost effective WC or bathroom suite in the most difficult of spaces for domestic or commercial projects.

What is a macerator pump?

A macerator pump is a type of wastewater pump that includes sharp blades or grinders to chop up solid waste (like human waste and toilet paper) into a fine slurry, which can then be pumped through narrow pipes typically from toilets or appliances where standard plumbing isn't practical.

How It Works:

Waste Enters: Wastewater from a toilet, sink, shower, or appliance flows into the macerator

Maceration: Internal blades grind solid waste into a slurry (similar to a blender).

Pumping: The pump then moves the slurry through small-diameter pipes (as small as 22mm), either horizontally or vertically.

Common Uses:

Installing toilets below the main sewer line (e.g. in basements or outbuildings)

Loft conversions or garden rooms without existing plumbing

Mobile homes, boats, and RVs

Adding bathrooms far from main soil stacks, where gravity drainage isn’t possible

Advantages:

Allows flexible bathroom or kitchen installations

Eliminates need for large-diameter waste pipes

Pumps waste uphill or long distances (often 5–10m vertically and up to 100m horizontally)

Saves on costly excavation work
