Our Backflow Testing Services

Backflow testing is required annually by most water districts in the South Bay. Your water provider will send a renewal notice each year before your certification expires. If you have not been notified, it is a good idea to check your last test date — devices that go untested can result in fines or water service disruption.

If your device fails its certification test, do not worry — it is fairly common, especially on older devices. Our technician will explain exactly what failed and provide a repair quote on the spot. We can often complete the repair during the same visit and re-test immediately. Most water districts give you an additional 14 to 30 days after a failed test to complete repairs.

Yes — we handle all paperwork. After your device passes its certification test, we submit the completed test report directly to your water provider on your behalf. You receive digital and printed copies for your records. You do not need to navigate any water district submission system yourself.

A standard residential backflow test takes about 15 to 30 minutes. Commercial tests with multiple devices may take longer depending on the number and type of devices. Most residential appointments — including testing, certification, and paperwork — are completed within an hour.

Yes. We provide comprehensive commercial backflow testing for office buildings, restaurants, medical facilities, retail centers, HOAs, industrial sites, and multi-tenant properties. We offer multi-device package pricing, after-hours scheduling to avoid business disruption, and consolidated documentation for property managers.

Absolutely. Many properties have multiple backflow devices — for example, one on the main water line and another on the irrigation system. We can test all devices during a single appointment and provide individual certification reports for each. Multi-device testing saves you time and often comes with discounted pricing.

For most residential properties, no. Backflow devices are typically installed outside near the water meter or main water shutoff valve. Our technician can access and test the device without entering your home. If your device is in a basement, crawlspace, or locked enclosure, we will coordinate access with you in advance.
