WaterWorks ™ 5-Way water quality test includes the most common tests needed to measure tap water quality. The same test is also used to test the water in the swimming pool. The test reveals the values of free chlorine, total chlorine, pH, total alkalinity and hardness. Dipping test strips provide an accurate and reliable result in 30 seconds.
- In good water, the alkality is more than 150 ppm. In Finland, alkalineity is often less than 60 ppm, which causes corrosion in piping.
- The pH limit value is between 6.5 and 9.5. The risk of corrosion is reduced when the pH of the water exceeds 7 and if the pH exceeds 9,5, lime contamination is easily generated.
- The disinfection power of the chlorine decreases as the pH rises. At low pH, chlorine increases the corrosion effect.
The water in the swimming pool should be slightly alkaline between pH (7.1-7.6), between free chlorine (1-5) ppm, total chlorine (2 -8) ppm, alkalinity (80-120) ppm.
The water quality test measures:
Water hardness: 0,25, 50, 120, 250,425 ppm (mg/L)
Total chlorine: 0,0.5, 1, 2, 4,10 ppm (mg/L)
Free chlorine: 0, 0.5, 1, 2, 4, 10 ppm (mg/L)
Alkalinity: 0.40, 80, 120.180.240 ppm (mg/L)
pH: 6.2, 6.8, 7.2, 7.8, 8.4 pH
How to perform a test:
- Remove the test iron from the foil package.
- Immerse the test strip in the water to be examined for 5 seconds so that the test pads in the strip sink below the water surface and swing the strip back and forth.
- Lift the strip from the water sample and shake off excess water. Then wait 25 seconds before reading the result
- Compare the colour of the test pads with the colour map on the package in pH, total alkaness, free chlorine, total chlorine, and total hardness. The result is readable for 30 seconds. Dry the colour chart of the package gently if it is wet.
Domestic water is water used in households as drinking water, for cooking and for other household purposes such as maintaining general hygiene. Domestic water is also water used in food premises and in public or commercial operator activities for human use and for the manufacture, processing, storage and placing on the market of foodstuffs.
If the domestic water does not meet the quality requirements set for it and the water may cause harm to health, the municipal health protection authority, together with the water supplying plant or water user, shall determine the cause of the water quality disturbance. The health protection authority shall order the water supplier to rectify the situation as a matter of urgency and shall provide instructions to water users on how to prevent the health hazard.
If you need a test to measure the quality of well water, for example, there is a test for it that has been developed for a purpose. Our other water quality tests can be found here.
