San Diego DMA · the notice on the door
Annual backflow test requirements
Cross-connection programs exist so non-potable water does not enter the public supply. Most local water agencies require a certified test on a regular interval — often yearly — and they mail you when it is due. Request that test here. This site does not replace the utility.
The notice is the specification
Due date, agency name, device count, and any ID they printed. That is what a tester needs to file. City of San Diego publishes its own cross-connection information; other cities and districts in the DMA have their own forms.
Follow the letter you received. Do not follow a blog post that was written for another state.
Who is allowed to test
California backflow testers hold specific certification. This website does not. A certified local tester may contact you if they accept the lead. Ask to see their current card before they open the device.
We will not publish a number we do not hold.
Typical cost and timing — not a quote
One device, easy access: often $75–$175 in this county. Several devices at one property are usually priced per device with a small efficiency if they sit together. Plan for a weekday visit; some testers will do Saturday.
A notice with two weeks left is routine. A notice that expired last month is still a request, not a guarantee of same-day.
If you already have a tester
Keep them. Annual testing works as a relationship, and this experiment is not trying to raid that stop. Use this page when you do not have anyone, or when you were told to find a replacement tester.
