How does ReFlow help save water?
By reusing filtered shower, bath, or basin water for toilets, you avoid using drinking water for flushing. This lowers your drinking water consumption and makes savings directly visible on your bill.
How can my family reduce water consumption?
Combine a greywater system like ReFlow with water-efficient taps and showerheads. This helps reduce water consumption without reducing comfort.
Is reusing shower water safe?
Yes, with the correct filtration techniques, shower water can be safely reused for non-potable uses such as toilet flushing.
Can I reuse bath water in an existing home?
In many renovation projects, reusing bath water is possible with adapted piping and a compact module. A technical screening determines the best setup.
Does ReFlow require a lot of maintenance?
Bath water, shower water, and basin water are filtered. Periodic filter replacement is enough to keep the system operational over time. Maintenance depends on the solution you use.
Does the system also work in renovation projects?
Yes, many installations happen during renovations. Compact solutions are available for apartments and terraced houses.
Can greywater be combined with rainwater?
Yes, greywater and rainwater can work in a complementary way. This increases total household water savings.
Are there rules in Belgium for greywater use?
Local regulations and technical standards may differ by region and municipality. Always ask an installer to confirm compliance. With ReFlow, you are always compliant with technical standards.
What is the payback period of a greywater system?
The payback period depends on household size, water price, and usage. With higher usage, the investment is generally recovered faster.
How do I start a greywater reuse project?
Start with an intake of home type, water consumption, and pipe layout. Then you receive a tailored proposal and installation planning.
