Protect Your Drinking Water with Certified Backflow Testing & Prevention
Backflow prevention devices help keep contaminated water from flowing back into your home’s or business’s drinking water supply. Coast Plumbing Solutions provides certified backflow testing, inspection, installation, and repair services throughout Santa Barbara County, helping property owners maintain safe water quality and comply with local testing requirements.
Certified Backflow Testing & Prevention Services
Backflow occurs when changes in water pressure allow non-potable water to flow in the opposite direction through a plumbing system. Without a properly functioning backflow prevention device, contaminants from irrigation systems, fire sprinkler systems, commercial equipment, or other cross-connections can enter the public drinking water supply.
Coast Plumbing Solutions provides certified backflow testing and prevention services for residential and commercial properties throughout Santa Barbara County. Our certified testers inspect, test, repair, and install approved backflow prevention assemblies to help protect your water supply while meeting applicable local water authority requirements.

What Is a Backflow Prevention Device?
A backflow prevention device is a specialized valve installed on a plumbing system to stop contaminated water from flowing backward into the clean water supply.
These devices are commonly installed on:
- Irrigation and sprinkler systems
- Fire sprinkler systems
- Commercial buildings
- Multi-family properties
- Industrial facilities
- Properties with specialized plumbing equipment
Many local water providers require certified testing of these devices on a regular schedule to verify that they continue to operate properly.
When Is Backflow Testing Needed?
Backflow testing may be required in several situations.
Annual Certification
Many backflow prevention assemblies must be tested annually to satisfy local water authority requirements.
After Repairs
A device should be tested after repairs or replacement to verify proper operation.
New Installation
Newly installed backflow prevention assemblies typically require testing before being placed into service.
Property Ownership Changes
Some municipalities or water providers may require updated testing documentation during property transfers or system modifications.
Water Utility Notification
If your water provider notifies you that testing is due, scheduling prompt service helps maintain compliance.
Suspected Device Failure
Visible leaks, unusual changes in water pressure, or damaged valves may indicate that the device should be inspected.

Backflow Services FAQs
What exactly is backflow, and why does my home need a prevention device?
Backflow is the unwanted reversal of water flow, which can pull dirty water, lawn chemicals, or fertilizer backward into your clean drinking water lines. A prevention device acts as a one-way mechanical check valve, ensuring that water can flow into your home but never backward into public lines.
Why did I receive a mandatory backflow testing notice from my local water department?
Local water districts are required by state law to protect the public water supply from cross-contamination. If your property features a dedicated lawn irrigation system, a fire sprinkler line, or a private well connection, you are mandated to have that device tested annually by a certified professional.
What happens if my backflow preventer fails its annual inspection?
If our gauges indicate that a check valve is leaking or a relief valve isn’t opening at the correct pressure, the device fails compliance. We will typically open the assembly, clean out any trapped mineral grit or sand, replace the internal rubber seals, and re-test it to clear your notice.
Where are residential backflow prevention assemblies usually located?
Most backflow preventers are installed outdoors near your property line, close to your main municipal water meter, or right next to your irrigation valve box. They are mounted above ground to allow proper drainage and to provide accessible access for testing technicians.
Can I test or certify my home’s backflow preventer assembly myself?
No. Local water purveyors will accept compliance reports only if completed and signed by a licensed plumber with an active cross-connection control certification. Testing requires specialized, annually calibrated differential pressure gauges.
What is the difference between an RPZ valve and a standard double check assembly?
A Reduced Pressure Zone (RPZ) valve features a built-in relief valve that physically dumps water onto the ground if either internal check valve fails, offering the ultimate protection for high-risk lines. A Double Check assembly features two sealed internal valves but lacks an open relief port, making it ideal for low-risk indoor lines.
