Hard Water Test Kit
Are you keen to understand how hard or soft the water is in your home? This at-home test kit is for you.
This video demonstrates the simple process. It’s child’s play!
The more droplets required, the harder the water.
Pink denotes that the water is hard. Blue denotes that the water is soft. The challenge is to see how many drops it takes to turn the water from pink to blue. This will show you how hard your water really is!
If the water goes blue after:
- 1 drop* = Your water is as soft as soft can be.
- 4 drops = Passable (you should still just about get bubbles in the bath)
- 8 drops = Moderately hard (will wash the daylights out of your skin and clothes)
- 12 drops = Exceptionally hard (a helmet in the shower is recommended)
*1 drop = 20 parts per million (ppm)
The hardness of water is determined by the milligrams of calcium carbonate per litre and is reported it in parts-per-million (ppm). In general, water with less than 60 ppm is considered soft, water with 60-120 ppm is moderately hard and water with greater than 120 ppm is hard.
