How to Use a Water Test Kit

You can use a water testing kit for a variety of reasons, including testing for contaminants or impurities in your drinking water. You can buy testing kits in hardware stores and they are relatively inexpensive. Most test kits provide testing strips and testing vials to fill with a sample of your drinking water. Routinely testing your water is important to ensure that your water is safe for drinking.
