This Safe Tap tap water rapid test tests the usability, purity and safety of water that cannot be judged by the appearance, smell or taste of the water. This quick test of tap water determines water hardness, pH, chlorine and copper concentrations
- pH: Low pH (less than 7) can cause corrosion in piping and with pH above 9,5, lime secretions are easily generated. If the pH of domestic water is more than 9.5, the water may cause it to
alkalinity causes a health hazard.
- Hardness: In good water the hardness is between 50-100 mg / l. Low hardness combined with low alkalinity can corrode metal pipes. And the high hardness increases the precipitation of lime in the piping.
- Very soft 0-55 mg/l
- Soft 55-110 mg/l
- Medium hard 110-160 mg/l
- Hard 160-215 mg/l
- Hard 215-320 mg/l
- Very hard 320+ mg/l
- Free chlorine: Water purification plants use chlorine to disinfect water. Chlorine inhibits the reproduction of microbes in piping. High levels of chlorine are harmful to health. WHO’s limit values for drinking water. Copper in domestic water comes mainly from the property’s plumbing. The maximum health-based value of copper in household water is 2,0 mg/l.

Well water: If the water comes to your household from a borehole or a ring well, it has its own well water quality test: use the test shortcut here
When passing through the soil, rainwater and meltwater filter and purified, and at the same time minerals dissolve in it. Water accumulates as groundwater in the soil layers above the bedrock, as well as in the fracture zones and cracks of the bedrock.
Finnish groundwater is usually mildly acidic, which means that their pH is less than 7. They are also usually soft, which means that the water has a low calcium content.
