FAQs
What is backflow and why is testing required for commercial properties in Delano?
Backflow is the unwanted reversal of water flow that can allow contaminated water to enter the public drinking-water system. Delano’s municipal code, in line with California State regulations, requires all commercial properties to install and regularly test approved backflow prevention assemblies. Annual testing ensures these devices are functioning properly so that fertilizers, chemicals, or industrial waste from your facility never siphon into the city’s potable water supply.
How often do commercial backflow prevention devices need to be tested in Delano?
The City of Delano mandates that every approved backflow prevention assembly at a commercial property be tested at least once a year. Certain high-risk facilities—such as food-processing plants, medical centers, and industrial sites using hazardous chemicals—may receive notices from the city’s Cross-Connection Control Program that require semi-annual testing. After each test, results must be submitted to the city within 10 days.
What does a backflow test involve, and how long does it take?
A certified backflow tester will: 1) shut off downstream water for a few minutes, 2) attach a calibrated differential-pressure gauge to the test cocks on your assembly, 3) verify the operation of check valves, relief valves, and air inlets, and 4) record the pressure readings on the official test form. For most commercial double-check or reduced-pressure assemblies, the procedure takes 20–30 minutes per device, and service is typically restored immediately afterward.
What happens if my commercial property fails the backflow test?
If the assembly does not meet the required performance criteria, our technician will document the failure on the city’s test form and provide you with a repair quote on the spot. Most failures can be corrected the same day by cleaning or replacing internal check valve parts. After repairs, a re-test is performed and the passing results are resubmitted to the City of Delano. The city generally allows 14 days for repairs and re-testing before enforcement actions or water-service interruptions are considered.
Are your plumbers certified to perform backflow testing and file reports with the City of Delano?
Yes. All of our commercial plumbers hold California State backflow tester certifications (ABPA or AWWA) and are registered with the City of Delano’s Cross-Connection Control Program. We handle the entire compliance process—testing, repairs, paperwork, and electronic submission—so you stay in full regulatory compliance without the administrative burden.
How can I prepare my business for a scheduled backflow test to minimize downtime?
1) Inform staff of the short water shutdown so critical operations can be paused. 2) Clear any storage or landscaping around the assembly for easy access. 3) Provide our technician with recent test reports and device locations. 4) If your facility cannot be without water, request that testing be done during off-peak hours or with a temporary bypass. These steps help our team complete the test quickly and keep your business running smoothly.
