Q&A

Check that the sanitary fixtures connected to the macerator are not leaking (toilet, faucet, etc.) - The device's check valve (located in the macerator's discharge elbow) may be leaking. If this is the case, clean or change the check valve.

Check whether the device is properly connected and whether the power supply is working properly. A foreign body may be blocking the device. You may be able to remove the foreign body by yourself. To do this, disconnect the power supply - IMPORTANT - before you begin, and separate the macerator from the toilet. Using a screwdriver, remove the obstruction that is preventing the blades from rotating. For all other issues, please contact your nearest authorized service technician.

You can find the instruction manuals for our devices directly on each product page and in our "Document center".
If it is an older product, you can easily locate it in the professional section using the instruction manual selector.

The Sanibroyeur Silence is no louder than a toilet flushing. The sound volume emitted in decibels may vary from one installation to another, depending on the product and especially the surroundings (tiled room or not, size and shape of the room, etc.). That is why we do not provide a value in decibels for our devices. However, the new silence range emits 10dB less than the previous version. Furthermore, it is crucial to follow the installation instructions to avoid the propagation of sound vibrations (no contact between the macerator and the wall, place the anti-vibration pads under the tank, mount the piping at intervals, etc.).

You can also opt to lay a layer of sound insulation between the macerator and the floor and/or wall for even better soundproofing.

The flush discharge generally triggers 2 to 3 cycles lasting 1 to 2 seconds each. If your device runs for longer periods than previously, it may be that the rubber ball cock system of your device requires cleaning/descaling. 

You can also use white vinegar or preferably, SFA's special SANIBROYEUR descaler to do this: disconnect your fixture from the power supply, then pour 2 litres of product in the bowl of your toilet. Leave it to work for a few hours and then reconnect to the power supply and flush.

Legislation requires that devices equipped with a grinding system drain into the wastewater network (commonly referred to as “black water”), whereas a simple sump pump may drain into the domestic wastewater network (referred to as “grey water”).

Furthermore, the drainage conduit of the grinder/pump must be directly connected to the main wastewater pipe (of large diameter).

The macerator does not require any special maintenance; however, to ensure many years of good service, we recommend that you clean and descale your macerator regularly.

SFA's special SANIBROYEUR descaler is designed to remove scale while preserving the internal workings of your device. This should be done more or less frequently depending on the hardness of your water. If you have an adaptable macerator, you can use standard products to clean your toilet bowl (similarly for the SANICOMPACT range). 

Please note, however, that unblocking products or any other acid should not be used as they may damage the internal elements of your adaptable macerator.

The lifetime of a Sanibroyeur depends mainly on proper installation and proper use. However, devices typically have a lifetime of 10 to 15 years with minimal maintenance, cleaning-descaling annually, and, depending on the quality of the water in your region, the replacement of the pressure switch membrane.

Water supply for all SANICOMPACTs works using a solenoid valve. There is therefore no need for a reservoir. The quantity of water used per cycle is 1.8L/3L or 3.8L/5L depending on the SANICOMPACT model. The water pressure must be at least 1.7 bars to ensure that the SANICOMPACT is properly rinsed.

The minimum water pressure for operating a SANICOMPACT is 1.7 bars. If your water pressure is lower than this, we recommend you install a traditional toilet bowl, behind which you can install an adaptable macerator like the Sanibroyeur, Sanibroyeur Pro, etc.

The drainage piping can be installed using standard PVC pipes.

The Sanidouche is a lift pump that evacuates the wastewater from a shower or a washbasin. For the device to operate properly, the axis of the shower trap must be located at least 8 cm off the ground. Non-compliance with this height requirement may result in water flowing back into the shower tray. We also recommend that you install a check valve on the outlet of any other sanitary fixtures connected to the Sanidouche (on the outlet of a washbasin for example). 

For more information, you can download the manual for this device from the product page or contact our technical support service at 01 44 82 25 55. It is open Monday to Friday from 8.30 am until 12:15 pm and from 1.45 pm to 5.30 pm.

One of the major advantages of SFA grinders and pumps is their ability to drain through very small diameters (ranging from 22 to 32 mm for the vast majority of products, while some larger pumps like the Sanicubic or the SANIFOS range drain in DN50 and DN100), thereby avoiding major construction work.
The recommended discharge diameter may vary by device. Please check the site's different product pages to find the most suitable discharge pipe diameters for your project.

It is entirely possible to install an SFA grinder even if you have a septic tank. The grinder only has a mechanical action (grinding and pushing) on materials, with no chemical effect whatsoever. It is therefore not incompatible with a septic tank.
