The equipment known as a WC grinder, toilet grinder, or grinding toilet is a small-sized device that allows you to enjoy a bathroom with a toilet, sink, and shower anywhere, without the need for construction work. It is common to place the WC grinding pump in a location where traditional drainage is difficult or unfeasible due to gravity reasons.

Toilet grinder how it works

If you want to install a bathroom in a basement, attic, motorhome, or another location where there is no plumbing, what you need is a toilet macerator. The toilet macerator works as follows:
  • When you flush the toilet, the tank empties, the water level rises inside the toilet tank, and this pressure causes the grinder motor to activate.
  • This grinder has blades that break down the toilet waste into small particles in a matter of seconds.
  • The water and particles form a liquid that is pumped, thanks to a turbine, to the drainage pipe.

What to know before buying a toilet grinder

Currently, there is a wide variety of toilet macerator models on the market. To help us choose, we should take a moment to consider the following:
Do I really need a grinder or a macerating pump?
The evacuation pump is more suitable for gray water, which comes from the shower, bidet, or sink. For this reason, if it is a room without a toilet, an evacuation pump would be sufficient.
How many toilets will there be?
The grinder we purchase should have as many inlets as there are sanitary fixtures in that space.
  • Only toilet: we can choose a one-inlet grinder or a compact model that includes a toilet and grinder. The outlet always has to be horizontal.
  • Toilet + sink: we will need a grinder with two inlets or a compact toilet grinder.
  • Toilet, sink, and shower: sanitary grinder with four inlets, in this mode, the necessary accessories that are not used are included. The pipe that connects the different sanitary fixtures to the grinder must have a slope of 3%.
Noise level
The noise level of the macerator can be bothersome. Currently, manufacturers like SFA are putting their efforts into minimizing this noise level. If you think this may affect you, we recommend that you consider this aspect when selecting the model, as some are quieter than others.
