What is a WC grinder?

The WC grinder or sanitary grinder is an electrical device that allows you to additionally install a toilet or complete bathroom anywhere in the home or business without the need for major construction work or having a general drain nearby. For example, installing a bathroom in the basement, garage, attic, storage rooms, or commercial premises.
The main features of toilet grinders are:
  • Compact designs connected to the power supply and to the sanitary fixtures.
  • They can be installed far from the downpipe or water drain.
  • They have one or more inlet connections to install multiple sanitary fixtures if necessary.
  • They grind and pump the dirty water to the appropriate downpipe.

How does a WC grinder work?

As we have mentioned, the function of the WC grinder is to grind and pump to evacuate the dirty water from the toilet or bathroom where it is installed. The operation consists of a series of steps:
  1. The grinder starts as soon as the user presses the flush button; it detects the increase in water and automatically turns on the motor.
  2. The blades inside the WC grinder shred the waste into small particles.
  3. The grinder's turbine pumps the water and waste into the drainage pipe and down the stack, whether on the same or a different floor.
  4. The toilet grinder is emptied and can be used again.

What should be taken into account when installing a WC grinder?

The installation of the grinder is simple and the maintenance is straightforward. It is only necessary to frequently check that the system is not obstructed by any foreign object that should not be flushed down the toilet and to use a special descaler for WC grinders following the instructions and frequency of the cleaning liquid.
Regarding the accessories, the Maldic models come equipped with all the accessories and adapters of different diameters to fit the necessary type of installation.
