FAQs
What is backflow and why is annual testing required for commercial properties in Oakdale?
Backflow is the undesirable reversal of water flow that can allow contaminants—such as chemicals, fertilizers, or bacteria—to enter the potable water system. The City of Oakdale, following California state plumbing codes and health regulations, requires all commercial buildings with backflow prevention assemblies (e.g., RP, DC, or PVB devices) to have them tested yearly by a certified tester. Regular testing verifies that the internal check valves, relief valves, and air vents are operating correctly and ensures that your property remains compliant while protecting the municipal water supply.
How often do I need to schedule backflow testing for my commercial facility?
In Oakdale, commercial backflow prevention devices must be tested at least once every 12 months. Certain high-hazard facilities—such as restaurants, medical centers, or industrial sites using chemicals—may receive a notice from the city requiring semi-annual inspections. It is best to schedule your annual test a few weeks before the due date listed on your city reminder notice to allow time for any repairs and re-testing if needed.
What does the commercial backflow testing process involve?
1. Shut-Off & Gauge Setup: Our certified tester will temporarily shut off your water, attach a calibrated differential pressure gauge, and isolate the device. 2. Valve & Relief Checks: We measure pressure across check valves, ensure the relief valve opens at the proper differential, and confirm that air inlets function correctly. 3. Data Recording: All readings are documented on the Oakdale Backflow Prevention Assembly Test Report form. 4. Restoration & Clean-Up: Water service is restored, and we confirm normal system operation. 5. Submission: We file the completed report electronically or in hard copy with the City of Oakdale Utilities Department within five business days, so your property’s compliance record stays current.
Are you licensed and certified to perform backflow testing in Oakdale?
Yes. Our technicians hold current California Department of Public Health (CDPH) Backflow Prevention Assembly Tester (BPAT) certifications and are registered with the City of Oakdale. We also carry a C-36 plumbing contractor’s license and full liability insurance. Copies of licenses, gauge calibration certificates, and insurance can be provided upon request.
What happens if my backflow prevention device fails the test?
If the device does not pass, we will explain the specific failure (e.g., check valve leakage, relief valve not opening, broken springs or rubbers). You will receive a written quote for repairs or replacement parts. After repairs are completed, a re-test is performed and the passing results are resubmitted to the city. The City of Oakdale allows a brief grace period—typically 10–30 days—for corrective action before potential fines or water service interruptions are assessed.
How much does commercial backflow testing cost, and what factors influence the price?
Standard single-device testing for a ¾"–2" assembly typically ranges from $95 to $150 in Oakdale, including filing fees. Larger devices (2½"–10"), multiple assemblies on one site, after-hours scheduling, or urgent same-day service can increase the cost. If repairs are needed, replacement parts and additional labor are billed separately. We offer bundled pricing for properties with several devices and multi-year maintenance agreements that can reduce per-test costs by up to 20%.
