Almost every water district in California requires an annual test on every backflow prevention assembly. Once your device is registered with a city, county, or water authority, you'll receive an annual notice requiring testing — we handle the test, any needed repairs, and file the paperwork on your behalf.

Missed deadlines typically result in fines or, in many districts, water shut-off until the test is filed. If you've just received a notice — or already missed the date — call us and we'll respond with available appointment dates to get you back into compliance.

Yes — filing is included. We submit the certified test report form directly to your water district through whichever method the jurisdiction requires (online portal, email, or mail), and we send you a copy along with the invoice.

If the device doesn't pass inspection, we'll notify you immediately, explain the issue clearly, and recommend the appropriate repair or replacement. We'll also schedule a return visit to complete the work and bring the system back into compliance. We avoid doing work without your approval.

Contact us by phone, email, or the scheduling form — we respond with available appointment dates. Because our routing is dynamic, we typically schedule by date rather than exact time windows. When we arrive, your choice: text notification on arrival, a knock on the door, or no notification at all. See our full scheduling and testing process at /how-it-works/.

Yes — residential homes, HOAs, commercial properties, restaurants, medical facilities, and industrial sites. Whatever the device and wherever it is, we test it.

RP (Reduced Pressure) assemblies are required for higher-hazard installations (irrigation with fertilizer injection, fire lines with additives, industrial process water). DC (Double Check) assemblies are for lower-hazard setups. Both must be tested annually.
