What is a Toilet connected to an SFA Sanitoilet Macerator?

Adding a toilet can be complicated when the new location has no suitable floor drainage connection. With a conventional solution, the project may require floor cutting or changes to the existing pipe route. This can make it more difficult to add a bathroom, especially in a home, shop or completed space.

In this situation, SFA toilet macerators from the Sanitoilet range collect water and waste from the toilet, reduce the waste size and pump the mixture to the drainage system. This provides a more flexible option for adding a toilet where connecting to existing drainage is difficult.

Key highlights

• Background: A toilet needs to be added where a suitable drainage route is not available.
• Challenge: A conventional toilet may require floor cutting or changes to the pipework.
• Solution: Connect the toilet to a Sanitoilet macerator pump.
• Result: Create an additional bathroom in a location that is difficult to connect to the drainage system.

What Is a Toilet Connected to a Sanitoilet Macerator?

Unlike a conventional gravity-drained toilet system, a toilet connected to a Sanitoilet macerator collects waste inside the unit, reduces its size and pumps the mixture through a discharge pipe to the drainage system or septic tank, depending on the building design.

Sanitoilet is a range of macerator pumps designed to collect black water from toilets. Depending on the model, the unit can also connect to selected sanitary fixtures. The number and type of connected fixtures should therefore be checked before selecting a product.

How Does Sanitoilet Work?

Sanitoilet operates automatically after each flush. Water and waste enter the unit, which is installed on the floor behind or beside the toilet. When the water level reaches the activation point, the integrated cutting mechanism reduces the waste to a fine slurry before the pump transfers it through the discharge pipe to the drainage system.

Step 1: Flushing and collection

When the user flushes the toilet, water and waste flow directly into the unit. Depending on the model design, the equipment is connected to the toilet and installed on the floor behind or beside it.

The connection between the toilet and the unit must follow the installation requirements of the selected model. The position of the unit may vary depending on the available space and the required pipe route.

Step 2: The water level activates the unit

Water and waste remain in the collection chamber for a short period. When the water level reaches the activation point, the internal control mechanism starts the motor.

The activation method may vary between models. This section therefore describes the operating principle in general terms and does not assume one identical configuration across the entire Sanitoilet range.

Step 3: The integrated cutting mechanism reduces the waste size

After the unit starts, the integrated cutting mechanism reduces the waste and mixes it with water to create a fine slurry.

The macerated mixture can then move more easily through a smaller discharge pipe. Only materials permitted by the product instructions should be introduced into the toilet.

Step 4: The pump transfers the mixture to the drainage system

After the waste has been reduced in size, the pump transfers the mixture through the discharge pipe to the drainage system or another approved connection point, depending on the building design.

When the cycle is complete, the unit stops and remains ready for the next flush. The pipe route, discharge point and connection method must be checked against the requirements of the selected model before installation.

How to Install Sanitoilet

Installing Sanitoilet involves connecting the unit to the toilet, discharge pipe, water supply and electrical system. The exact steps may vary between models, so the technical instructions must be checked before installation and commissioning.

Step 1: Connecting the discharge pipe

First, determine the route from the unit to the drainage system. Some configurations may require a Y-connection or another suitable connector for the existing pipework.

The pipe size, direction and connection point must follow the technical documentation for the selected model. All joints should be checked carefully to reduce the risk of leakage during use.

Step 2: Connecting the toilet to the unit

The unit must be connected directly to the toilet using the correct position and supplied fittings. For floor-mounted models, the equipment is generally installed behind the toilet.

Check that the connection is stable before completing the discharge pipe, water supply and electrical connections.

Step 3: Connecting the water supply and electrical system

The toilet must be connected to a suitable water supply for flushing. The water connections should match the equipment and be checked for leaks after installation.

Sanitoilet also requires a suitable electrical supply for the motor and pump. The socket, protective devices and electrical circuit must be installed according to the model instructions and applicable site safety requirements.

Step 4: Checking the ventilation requirements by model

Ventilation requirements depend on the product. Based on the available information, Sanicompact Pro requires a ventilation system, while some other Sanitoilet models such as Sanibest Pro do not require the same configuration.

The ventilation requirements for the selected model should be confirmed before installation. After completion, the system should be tested to check the connections, pumping cycle and overall operation.

Which Sanitoilet Models Suit Different Needs?

Sanitoilet includes several product options for different applications, from adding one toilet to installing a complete bathroom. The selection should be based on the number of connected fixtures, installation position, expected frequency of use and maintenance requirements.The most suitable product should be selected after checking the number of inlets, connected fixtures, discharge route, installation position, maintenance access and technical requirements of the project.

Conclusion

Adding a bathroom is not only about connecting sanitary fixtures to an existing pipe. When the installation location is difficult to connect to the current drainage route, the project needs a suitable solution to collect, macerate and pump wastewater.

Saniflo and Saniaccess 1 are suitable for adding one toilet. Sanitop and Saniaccess 2 are designed for a toilet and hand basin, while Saniaccess 3, Sanipro XR and Sanibest Pro can connect to more sanitary fixtures. Sanipack and Sanigrind Pro are suitable for selected wall-hung configurations, while Sanicompact Pro is a toilet with an integrated macerator pump.

The right model should be selected according to the number of connected fixtures, installation position, discharge route, frequency of use, maintenance access and project requirements.
