  • two capacities for 2 to 4 or 4 to 8 people depending on water hardness and consumption

Performance class (capacity)

The capacity depends on your water hardness and water consumption. You can determine the capacity using our capacity calculator or this rule of thumb:

Water hardness rule of thumb
Medium-hard water (8–14 °dH) Number of people x 7.5
Hard water (14–21 °dH) Number of people x 10
Very hard water (over 21 °dH) Number of people x 12.5

Example (4 people with a water hardness of 20): 4 x 10 = 40

Variant: LEYCOsoft Pro 9 water softener with app control in a worry-free package including installation

The product has been installed for 1.5 months now and is in perfect use. As a household of 4 people (2 adults + 2 children) we have an annual consumption of around 90 m3. The system regenerates approximately every 3-4 days. If you take the full program including a full bath, it regenerates every 2-3 days. The connection via app is easy to set up and generally good. However, the cloud-based service is not completely reliable, and the service is sometimes unavailable. There is an integration for Homeassistant, although the aforementioned outages are a disadvantage for this. This does not detract from the actual purpose of the system. In the beginning we could detect a slight aftertaste, but this no longer occurs. I assume that this is due to the old existing lines. In this respect: very satisfied with the product, also in combination with the carefree package. The appointment arrangement and installation went very well.
