Hard Water / Soft Water Test Kits
Many people prefer to keep an eye on their softener themselves and check that it is working as it should be. There are two types of kits on the market:
Kit 1: Yes/No tablets
These will give you a reading as low as 50PPM of hardness, so in most circumstances, they are perfect for determining which taps in your home are on soft or hard water, or for just knowing if your softener is producing softened water.
Kit 2: Accuracy Test Kit
The ACCURACY Test Kit is the most accurate way outside of a laboratory to test your water quality and will measure down to 0PPM hardness.
