In most areas, including Spokane, your backflow prevention device must be tested annually to stay compliant with local water regulations. Regular testing helps ensure your drinking water stays safe from contamination.

If your device fails, we’ll explain the issue clearly and walk you through the next steps. In most cases, we can repair or replace the device on the spot to bring it back into compliance.

Most residential backflow tests take about 20–30 minutes, while commercial or complex systems may take a bit longer. We also handle all the paperwork so you don’t have to.
