Check the water before treating it
Read the TESTED result and the contaminant breakdown. LABELED is the name attached to the container; changing that name does not remove anything from the water.
A container can test as Pure Water while still carrying a High-Quality Water label. Pure Water is also not necessarily an absolute zero-contaminant reading: a 99.97% result can display that grade.
Use the WaterPurifier machine
- Double-click the WaterPurifier to open it.
- Put a water container in Water Container.
- Supply power through Power Source. Check the machine’s displayed energy requirement after changing modules.
- Leave the machine to work overnight.
- Test the water again and compare the remaining contaminants.
Purification is gradual. One unmodified-machine example improved from 92.71% to 93.50% overnight and was still Rustwater. One night in the machine is not a promise of Pure Water.
| What to check | What it tells you |
|---|---|
| TESTED grade and percentage | The measured water quality |
| Contaminant breakdown | What still needs treatment |
| Required energy | Whether the installed power supply can support the machine |
| LABELED name | How the container is presented, rather than its measured purity |
HydraTech is a different tool
The HydraTech Micro Water Purifier is used on a water container. Its tooltip describes a target of Basewater and a cost of 1 durability per 100 ml. Do not treat it as the overnight machine or expect that target to mean Pure Water.
“This water is already Basewater or better” means the tool will not perform that treatment. It is not a successful-purification message and does not tell you the exact percentage. Test the container to find out what is actually in it.
Why the water is still not pure
Check power, the full contaminant list and the next morning’s reading before replacing equipment. A result that has improved but remains Rustwater is different from a machine that did not run at all. Module configuration and the starting mixture matter; a setting used on one bottle is not a universal recipe for every source of water.
For cold-water questions, see the fridge guide. Chilling and purification are separate jobs.
