​Why Test Your Water?
  • Customized Recommendations: Water quality varies. Testing helps us find the right filter to meet your unique needs.
  • Comprehensive Analysis: Our free test covers iron, manganese, tannins, nitrates, pH, hardness, and more. For health-related concerns, such as e-coli or harmful chemicals, we can recommend a certified lab.
How to Submit Your Sample:
  • Draw Your Sample: Collect at least 8 ounces in a leak-proof plastic bottle (no glass) from as close to the source as possible—avoid drawing from existing filtration systems.
  • Existing Customers: Send two samples—one untreated, one treated—to check system performance.
  • Include the Form: Use our free water analysis form by clicking the image above. Print, complete, and send it with your sample.
Why Choose RainDance?
We customize our recommendations based on your water’s unique chemistry for optimal filtration performance. Our free testing is obligation-free, so you get results even if you don’t purchase a filter.
ATTENTION: For any concerns about the safety of your water—such as e-coli, coliform bacteria, arsenic, harmful chemicals, or metals—we recommend using a certified testing facility capable of comprehensive microbiological analysis. We can refer you to a qualified testing facility upon request.
