Level 2 Testing is Do-It-Yourself testing that you yourself can do in your own home using a Testing Kit. After you’ve done Level 1 Testing, Level 2 Testing can further clarify if your observations are correct. If your test results reveal the presence of a Contaminant that is a cause for concern, you can either proceed to determine the best Treatment options or continue to Level 3 Testing. The Level 2 tests are typically low-cost self-diagnostic kits, low-cost water quality meters, or field test kits used by water treatment professionals. In most cases, these kits provide an insight into what is not likely the cause, but in some cases they can point to a specific type of problem, condition, or Contaminant.
Following DIY water testing, we strongly recommend using this information to determine the need for any additional specific testing, such as: Level 3 and Level 4 Testing. In most cases we recommend the informational water testing services (Level 3) before conducting a Level 4 Certified Testing analysis. Level 2 testing should never be used to size or select a water treatment system, but this information can be used to assist in the sizing, selection, and design by identifying the probable existence (but not magnitude) of a particular problem. At a minimum, Level 3 testing should be conducted prior to considering the installation of a Water Treatment System.
If you are unsure what to test or what may be causing your water problem or concern, we suggest using our Drinking Water Self-Diagnostic Tool .
This tool identifies water issues such as hard water, discolored water, water that smells or has an odor, contains iron, is dirty, or leaves a stain, to name a few.
The Drinking Water Self-Diagnostic Tool serves as a preliminary diagnosis of your water’s quality to be used to determine what next steps you would need to take to remedy any health or aesthetic issues you may have. These steps may include water testing (Level 2 or 3) followed by a treatment solution ranging from a basic water filter to a more advanced treatment solution.
For example, if you have a tankless water heater, a common treatment solution is to pretreat the water to reduce hard water issues (water softener), hardness, and scale formation.
