Drinking water treatment: verified water quality throughout your home
How good is your tap water really? WaterTool analyses your drinking water quality, explains the readings in plain language and recommends exactly the treatment your home or business actually needs.
Drinking water treatment starts with a water analysis
Drinking water in Germany is strictly monitored – yet the condition of your building installation, the local network and the water hardness decide what actually reaches your tap. That is why every WaterTool project starts with an analysis: hardness, chlorine, nitrate, heavy metals and microbial load are measured and explained clearly.
Only then do we make a recommendation. Depending on the findings that may be targeted filtration – described in detail on our water filters & reverse osmosis page – or treating the water hardness, which we cover under softening & limescale protection. Often a smaller measure is enough.
We accompany the whole path: analysis, recommendation, clean installation, hand-over and, on request, regular maintenance with filter changes, hygiene checks and spare parts service. That keeps your drinking water quality verifiable long term.
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.
