Water Testing for Home Water Problems
Start with information, not assumptions. Choose a water test that fits your source water and the concern you want to investigate, then use the results and product labels to compare an appropriate water-treatment path.
Choose the right treatment path
Testing is especially useful when you are on a private well, notice a change in water, or want to investigate a specific concern. A result does not prescribe a system by itself; match the product to the result, flow needs, and installation setting.
Start with a water test when you need more clarity about the source water or a particular concern.

- Choose a broad drinking-water test when you need a general starting point for a home or building.
- Choose a test that includes bacteria only when that question matches your source water and testing needs.
- Use a targeted PFAS, metals/minerals, or tannins test when you are investigating that specific concern rather than guessing.
