We respond with available appointment dates. 2. **We show up and test.** A certified tester arrives on the scheduled date and performs the test on-site. The customer can choose text notification on arrival, a knock on the door, or no notification at all. 3. **We file the report.** We submit the signed report directly to the appropriate water district — through their online portal, email, or mail, depending on the jurisdiction — and send the customer a copy along with the invoice. If the device does not pass inspection, we notify the customer immediately, explain the issue clearly, recommend the appropriate repair or replacement, and schedule a return visit to bring the system back into compliance. We never do work without approval. We also track every customer's annual due date by their local Authority Having Jurisdiction (AHJ) and send reminders before the next test is due. ## Water districts we regularly file reports with - Turlock Irrigation District - Modesto Irrigation District - City of Stockton Municipal Utilities - Merced Irrigation District - East Bay Municipal Utility District (EBMUD) - San Francisco Public Utilities Commission (SFPUC) - Valley Water (Santa Clara Valley Water District) - California Water Service …or whichever agency issued your annual notice. ## Contact - **Phone:** (800) 684-8346 - **Email:** citycertifiedbackflow@gmail.com - **Hours:** Monday–Saturday, 7:30 AM – 5:00 PM Pacific.

The district sends an annual notice with a deadline. - **What if I miss the deadline?** Missed deadlines typically trigger fines or, in many jurisdictions, water shut-off until the report is filed. We respond quickly and can usually get you back into compliance. - **What does it cost?** Pricing varies by device type, location, and access. Residential testing typically runs $45 to $95; commercial runs $75 to $175 per device. Repairs and installs are quoted on-site before any work begins. - **Do you file the report for me?** Yes — filing is included. We submit through whichever method the jurisdiction requires. - **What if my device fails?** We notify you immediately, explain the issue, recommend repair or replacement, and schedule a return visit. No work happens without your approval. - **RP vs DC?** RP (Reduced Pressure) assemblies are required for higher-hazard installations (irrigation with fertilizer injection, fire lines with additives, industrial process water). DC (Double Check) is for lower-hazard setups. Both must be tested annually. - **Residential and commercial?** Yes — residential homes, HOAs, commercial properties, restaurants, medical facilities, and industrial sites. ## Key pages - Home: https://www.citycertifiedbackflowprevention.com/ - About: https://www.citycertifiedbackflowprevention.com/about/ - How testing works: https://www.citycertifiedbackflowprevention.com/how-it-works/ - Services overview: https://www.citycertifiedbackflowprevention.com/services/ - Residential backflow testing: https://www.citycertifiedbackflowprevention.com/services/residential-backflow-testing/ - Commercial backflow testing: https://www.citycertifiedbackflowprevention.com/services/commercial-backflow-testing/ - New installation & replacement: https://www.citycertifiedbackflowprevention.com/services/new-installation-and-replacement/ - 24-hour emergency service: https://www.citycertifiedbackflowprevention.com/services/24-hour-emergency-service/ - Service areas: https://www.citycertifiedbackflowprevention.com/service-areas/ - FAQ: https://www.citycertifiedbackflowprevention.com/faq/ - Reviews: https://www.citycertifiedbackflowprevention.com/reviews/ - Schedule a test (contact): https://www.citycertifiedbackflowprevention.com/contact/
