The macerator allows a toilet to be installed in any position, regardless of whether there is a drain line nearby.
When renovating a flat, the layout of rooms is often influenced by structural constraints such as windows, balconies, load-bearing walls or sewer lines.
For example, a new bathroom generally has to be located close to a drain line. However, the toilet macerator removes this constraint, allowing the toilet to be installed anywhere, even away from the sewer line.

What is a toilet macerator
The macerator is a device that shreds and grinds faeces and toilet paper, pushing them towards the drain. This device has a cassette shape, which can be positioned behind the toilet or recessed in the wall, depending on the model.
Thanks to the macerator, it is possible to create a bathroom even in the absence of a traditional drain, allowing a second bathroom to be installed or the main one to be moved to another room. It can also be useful in a traditional bathroom to solve clogging problems due to poor pipe slope.
How does a toilet macerator work
The macerator is powered by electricity and requires a nearby electrical outlet. When switched on, the device shreds the waste in the toilet and pumps it into the connected pipes. The waste is turned into a mush that is pushed through the system. An electronic valve prevents odours from returning and restores the water immediately.
Installation pipes
The slurry produced by the macerator is sufficiently fluid to be pumped up to a height of four metres.
The connection pipe to the drain system has a diameter of 32 mm, much smaller than the 90 mm of traditional pipes, allowing it to be easily concealed inside a false ceiling up to the sewer line.

Advantages of toilet macerator
Summing up, then, we can certainly state that there are many advantages of installing a macerator:
- Toilet installation anywhere in the house without major work
- Prevention of blockages in conventional drain systems
- Discreet design that does not affect the environment
Macerator models
There are various models of toilet macerators:
- Macerators to be installed behind the toilet
- Built-in macerators
that can be concealed behind a wall, ideal for wall-hung toilets - Sewage pumps
usable for showers, washbasins or dishwashers, preventing clogging - Toilet with built-in macerator
Installation and maintenance
The installation of a toilet macerator requires some specific precautions. First of all, it is essential to ensure that there is an electrical outlet nearby, as the device runs on electricity.
In addition, it is advisable to position the macerator as close as possible to the toilet to minimise the length of the necessary pipes. A qualified technician should carry out the installation to ensure proper functioning and safety of the device.
Maintenance
Regular maintenance is crucial for the proper functioning of the toilet macerator. Here are some tips for keeping it in good condition:
- Periodic cleaning: use limescale removers to prevent limescale build-up that could damage the mechanism
- Checking valves: periodically check the condition of the valves to ensure that they are working properly and to prevent the return of unpleasant odours
- Proper use: avoid throwing unsuitable items such as nappies, wet wipes or materials that could damage the macerator into the toilet

The macerator is an extremely useful device, especially in locations with structural constraints. It is important to carry out regular maintenance to prevent damage, such as limescale build-up, which could impair the operation of the device.
If installed and maintained correctly, the macerator can offer a flexible and practical solution for flushing, making it possible to create toilets in otherwise impractical locations.
