Can you tell me how to measure the hardness of my tap water?

Sure. Tap water hardness is typically measured in units of a log(10) scale. For example, the recommended level of hardness for a sink is between 1 and 5. However, the hardness of your water isn’t going to change all that much. You can tell the level of hardness by its color.

Okay. How can I measure my sink water's hardness at home?
user
You can purchase a pH tester at your local hardware store. These devices are also called “precipitometers” or “ion analyzers”. You can find the recommended pH testing range here.
assistant
No I want to measure the hardness, not the pH?
