Drinking water treatment for home & business
Clean, great-tasting drinking water straight from the tap – with modern filter, reverse-osmosis and softening systems from WaterTool. Individually planned, professionally installed and reliably maintained.
Drinking water treatment that fits your everyday life
Whether single-family home, apartment, holiday house or small business – WaterTool plans, installs and maintains drinking water systems precisely to your needs. We always start with a thorough analysis of your tap water and give you transparent advice on the best technical and commercial options.
Our systems reliably remove limescale, chlorine, heavy metals, nitrate, bacteria and microplastics. The result: water that tastes better, protects your appliances and takes care of your family or guests.
Installation is carried out cleanly and discreetly by our experienced specialist team. We then explain every function and, on request, take over regular maintenance – including filter changes, hygiene checks and spare parts service.
What we build for you
From the first water analysis to long-term support: WaterTool delivers every step of your drinking water treatment from a single source.
We test hardness, chlorine, nitrate, heavy metals and microplastics directly at your home or business. Based on the readings we recommend the right treatment – no off-the-shelf standard solution.
Whether activated carbon, reverse osmosis or softening: we configure your system precisely for your water quality, consumption and space. You get a system that fits your household technically and commercially.
Our certified installers fit the system cleanly, discreetly and to standard. After commissioning we explain every function and document the water values for your records.
With our maintenance service your drinking water system stays powerful and hygienic long term. We replace filters, check seals and deliver spare parts on time – as an all-inclusive package on request.
