During the renovation of a family kitchen, the homeowner wanted to move the sink to a new location that better suited the layout and daily usage needs.  However, the proposed location was not suitable for connecting to the existing pipe through gravity drainage.

Sanivite was selected to collect and pump greywater from the sink to the existing drainage system. This gave the kitchen renovation greater flexibility without necessarily requiring a complete change to the existing drainage route.

 

Key highlights

  • Project context: The homeowner wanted to relocate the sink to improve the kitchen layout.
  • Challenge: The new location could not connect easily to the existing drainage pipe through gravity drainage.
  • Solution: Sanivite collects greywater from the sink and pumps it to a suitable connection point.
  • Result: The sink was relocated while remaining connected to the existing drainage system.

 

Challenge

The existing kitchen needed to be adjusted to better suit the family’s preferred layout and usage needs. The proposed sink location was convenient in terms of function but could not connect directly to the existing pipe through gravity drainage.

The renovation therefore needed to address two requirements at the same time: retain the planned sink location and transfer the greywater to the existing drainage system. This was the basis for selecting Sanivite for the project.

 

Solution: Sanivite for the New Sink Location 

Sanivite belongs to the Sanigrey greywater drainage solution range. It was selected to support the relocation of the sink within the family kitchen.

The unit collects greywater from the sink at the new location and pumps it to the existing drainage pipe. This allows the sink position to be considered according to the kitchen layout and household needs, rather than depending only on the availability of gravity drainage at the installation point.

The solution provides the following benefits:

  • Connection to the existing drainage system: Wastewater from the sink is pumped to a suitable connection point while making use of the existing system.
  • Greater flexibility when positioning the sink: The new location can be considered according to the kitchen layout and usage requirements.
  • Suitable for an existing kitchen under renovation: The solution can be considered where the kitchen layout and technical systems are already in place.

Project result: The sink was relocated

Sanivite gave the homeowner an additional option for relocating the sink within the existing kitchen. Greywater from the new location was collected and pumped to the existing drainage pipe instead of relying entirely on gravity drainage.

As a result, the sink could be positioned according to the family’s usage needs while the existing drainage system could still be used. The Sanivite solution made the kitchen adjustment more flexible without necessarily requiring a complete change to the existing drainage route.

 

Conclusion: A flexible solution for kitchen renovations

Relocating a kitchen sink involves more than changing the position of the cabinets or worktop. The project must also consider how wastewater from the new location can connect to the existing drainage system.

When the new location is difficult to connect directly or is not suitable for gravity drainage, Sanivite can collect greywater from the sink and pump it to a suitable connection point. This gives homeowners another option when renovating an existing kitchen while allowing the existing drainage route to remain in use.

The final installation method should be determined according to the kitchen layout, pipe route, connection point, power supply, and actual site conditions.
