Backflow Testing & Repairs
Protect Your Water Supply, Stay Compliant
A backflow prevention device has one job: stop contaminated water from flowing backward into your property's clean water supply. It's a small piece of equipment with a big responsibility, and most Southern California water agencies require it to be tested annually to make sure it's still doing that job correctly.
For commercial and industrial properties, backflow testing is usually a non-negotiable part of staying compliant and avoiding fines. Multi-family communities and HOAs often have multiple devices across a property that all need to stay current. Hospitals and schools face even stricter requirements given the health stakes involved. And homeowners with irrigation systems or certain plumbing setups may have a backflow device on their property without realizing it needs annual attention too.
West Coast Hydro-Jet has provided backflow testing, backflow prevention device repair, and certification throughout Los Angeles, Orange County, the Inland Empire and San Diego for more than 34 years. Our technicians are certified to test, repair, and certify backflow devices, and every test is performed by our own crew, not a subcontractor.
It's Not Optional, and That's a Good Thing
Local water agencies across Southern California require annual backflow certification because the consequences of a failed device are serious: contaminated water flowing back into a property's clean water supply, or worse, into the broader municipal system. That risk is why testing isn't a suggestion, it's a mandatory requirement enforced by water providers, with real consequences for properties that let certification lapse.
Beyond the legal requirement, annual testing simply confirms that a device that's protecting your water supply is still working the way it's supposed to. A device can fail silently, with no visible sign anything is wrong until a test catches it.
The Cost of Letting Certification Lapse
Skipping backflow testing puts a property at risk on more than one front. Water agencies can issue fines for lapsed certification, and in some cases, they can shut off water service entirely until the device is tested and certified. Beyond the compliance risk, an untested device that fails silently creates a real contamination risk for everyone on the property's water system, from tenants and employees to patients, students, or residents depending on the property type.
Staying current on testing is a small, predictable cost compared to the fines, water shutoffs, and liability that come with letting it lapse.
What to Expect During Testing
Our certified technicians test each backflow prevention device on your property to confirm it's holding pressure correctly and preventing reverse flow as designed. If a device passes, we file the certification with your local water agency on your behalf, so you don't have to manage that paperwork yourself. If a device fails, we repair or replace it and retest before certifying, so the entire process is handled in as few visits as possible.
For properties with multiple devices, like larger commercial buildings or multi-family communities, we coordinate testing across all devices in a single visit whenever we can, to minimize disruption to your operations.
When to Call Between Scheduled Tests
Most backflow issues are caught during annual testing, but a few signs can indicate a problem before your next scheduled test:
- Discolored water coming from taps, which can indicate contamination has already entered the system
- Unusual taste or odor in tap water
- A noticeable drop in water pressure, which can point to a device that isn't sealing correctly
- Visible leaking or corrosion around the backflow device itself
- A notice from your local water agency flagging an issue or an approaching deadline
If you notice any of these, it's worth having a device inspected right away rather than waiting for the next annual test.

Frequently Asked Questions About Backflow Testing
How often does a backflow device need to be tested?
Most Southern California water agencies require annual testing. Some jurisdictions or property types may have different requirements, and we can confirm what applies to your specific property
What happens if my backflow device fails testing?
We repair or replace the device and retest it to confirm it passes before filing certification with your local water agency.
Who is responsible for filing backflow certification?
The property owner is typically responsible, but West Coast Hydro-Jet files the certification with your local water agency on your behalf after a successful test.
Do residential properties need backflow testing?
Some do, particularly homes with irrigation systems or certain plumbing configurations. If you're not sure whether your property has a backflow device, we can check during a service visit.
What happens if I don't get my backflow device tested?
Water agencies can issue fines for lapsed certification and, in some cases, shut off water service until the device is tested and certified. An untested device also creates an ongoing contamination risk.
