Our Certified Backflow Testing Process
Our Professional Backflow Testing Process
At Advanced Irrigation, every backflow test follows a systematic procedure to ensure your backflow prevention assembly is operating correctly and complies with local testing requirements. Although most residential tests take only 15 to 25 minutes, several important steps are completed during every appointment. Our goal is not simply to pass or fail a device, but to verify that your backflow preventer is functioning properly and protecting your drinking water. Here’s what you can expect when we arrive.
Step 1 – Inspect the Backflow Assembly
Every appointment begins with a visual inspection of the backflow preventer. Before connecting our testing equipment, we carefully examine the assembly for any obvious issues that could affect its performance or indicate that repairs may be needed. During this inspection, we look for:
• Visible water leaks
• Cracked or damaged components
• Corrosion
• Signs of previous repairs
• Freeze damage
• Missing parts
• Proper orientation of the assembly
• Accessibility for safe testing
Many problems can be identified during this initial inspection before the performance test even begins. If we notice anything unusual, we’ll explain our findings and answer any questions before moving forward.
Step 2 – Perform the Certified Performance Test
Once the visual inspection is complete, we connect our calibrated backflow test gauge to the assembly.
Using specialized equipment, we measure how the internal components of the backflow preventer perform under specific test conditions.
Unlike a simple visual inspection, this test verifies that the internal safety mechanisms are working correctly.
During testing, we evaluate the performance of critical components such as:
• Internal check valves
• Relief valve (on RPZ assemblies)
• Springs
• Sealing surfaces
• Pressure differentials
• Missing parts
• Overall operating performance
These components work together to prevent contaminated water from flowing backward into the potable water system.
Because many of these parts are located inside the assembly, they cannot be evaluated by sight alone. Specialized testing equipment is required to confirm the device is operating within the required standards.
Step 3 – Record the Test Results
Every certified backflow test requires detailed documentation. Once testing is complete, we record all required information, including:
• Property information
• Device manufacturer
• Model number
• Serial number
• Device size
• Test readings
• Pass or fail results
• Testing date
• Certification information
Accurate documentation is an important part of the testing process and helps ensure compliance with local jurisdiction requirements.
Step 4 – Electronically Submit the Required Report
After completing the test, we electronically submit the required report when applicable for your local jurisdiction.
This report includes the information collected during the inspection and performance test, along with our certification as the testing professional.
In many cases, your email address is included with the submission so you also receive a copy of the completed report for your records.
This gives homeowners documentation showing that the required annual testing has been completed.
Step 5 – If Your Device Passes
If your backflow preventer passes the performance test, that’s great news.
It means the assembly is operating properly and continues to provide the protection it was designed for.
Once the report has been submitted, your annual testing requirement for that inspection cycle is complete.
We recommend continuing annual testing so the device can be monitored as it ages and continues protecting your irrigation system and drinking water supply.
Step 6 – If Your Device Does Not Pass
Not every failed backflow test means the entire assembly needs to be replaced. In many cases, the problem is caused by normal wear of internal components such as springs, rubber seals, or check valves. Mineral buildup, debris inside the assembly, or damage from freezing temperatures can also affect performance. If your device does not pass the inspection, we will explain exactly what caused the failure and discuss the available repair options. Unlike some companies that make immediate repair recommendations without explanation, we believe homeowners should understand what needs to be repaired and why.
Step 7 – Repair Recommendations and Customer Approval
If repairs are necessary, we typically do not complete them during the same appointment.
Most repairs require replacement parts that are specific to the manufacturer and model of your backflow assembly. To ensure the correct components are installed, we first identify the required parts and prepare a detailed repair estimate.
You’ll receive a clear quote outlining the recommended repairs. Once you’ve had an opportunity to review and approve the estimate, we’ll schedule a return visit to complete the work.
This process allows you to make an informed decision without feeling pressured and ensures the correct replacement parts are used for your specific assembly.
Step 8 – Retesting After Repairs
After repairs have been completed, the assembly must be tested again.
This final test confirms that the repaired backflow preventer now meets the required performance standards and is functioning correctly.
Once the device passes the retest, we submit the updated certification electronically, completing the process and helping ensure your property remains compliant with local requirements.
Pro Tip : (Failures & Repairs
Don’t ignore a leaking relief valve. While some leaks are minor, continuous discharge often indicates the assembly should be inspected by a certified backflow tester.
Why Homeowners Appreciate Our Process
We believe homeowners deserve more than a pass or fail result. Our goal is to explain the condition of your backflow preventer, answer your questions honestly, and provide recommendations based on what your assembly actually needs—not on unnecessary repairs or replacements. Whether your device passes on the first visit or requires repairs, you’ll always know what we’re doing, why we’re doing it, and what to expect next.
Did You Know?
A backflow preventer is one of the few plumbing devices specifically designed to protect not only your home, but also the public drinking water system that serves your entire neighborhood.
Why Backflow Devices Fail & What Happens Next
Why Do Backflow Preventers Fail?
Like any mechanical device, a backflow preventer experiences normal wear over time. Although these assemblies are built to last for many years, they contain moving parts, springs, rubber seals, and check valves that are constantly exposed to water pressure, minerals, and environmental conditions.
A failed annual test doesn’t necessarily mean the assembly was poorly installed or neglected. In many cases, it simply means one or more internal components have reached the end of their service life and need to be repaired or replaced.
The purpose of annual testing is to identify these issues before the assembly can no longer provide the level of protection it was designed for.
The Most Common Reasons Backflow Devices Fail
1. Normal Wear and Tear
The most common cause of failure is simply age. Over time, the internal springs lose tension, rubber seals become brittle, and moving components no longer seal as tightly as they did when the assembly was new. These changes happen gradually and are often impossible to notice without certified testing.
2. Mineral Buildup
Northern Virginia’s water naturally contains minerals that can accumulate inside a backflow assembly over the years.
Calcium deposits may interfere with the movement of internal check valves or prevent sealing surfaces from closing completely. Even a small amount of buildup can affect the assembly’s ability to perform correctly during testing.
3. Debris Inside the Assembly
Small rocks, sand, rust particles, or other debris can occasionally enter the backflow preventer through the water supply.
When debris becomes trapped between sealing surfaces, the internal check valves may not close completely. This is one of the reasons why a device that appeared to be working normally can still fail its annual certification.
4. Freeze Damage
One of the most serious causes of failure is freezing temperatures. If water remains inside the assembly during winter and freezes, it expands with tremendous force. This can damage internal components or even crack the body of the backflow preventer. In some cases, freeze damage is immediately visible. In others, the damage may not become apparent until the annual performance test. Proper winterization is one of the best ways to protect your investment and extend the life of your backflow preventer.
5. Internal Component Failure
Even when the outside of the assembly looks perfect, important internal parts can wear out over time. Components that commonly require replacement include:
• Springs
• Rubber Seals
• Check valve assemblies
• O-rings
• Relief valve components (on RPZ assemblies)
These parts are designed to be serviceable, which means many backflow preventers can be repaired rather than replaced.
What Happens If Your Backflow Preventer Fails?
Receiving a failed test result can be concerning, but it doesn’t automatically mean you’ll need an entirely new backflow preventer. In many cases, the assembly can be successfully repaired by replacing worn internal components and then retesting the device. Our first priority is always to determine the most practical and cost-effective solution for your specific assembly. We Explain the Results If your device doesn’t pass the performance test, we’ll clearly explain:
• Which part of the assembly failed
• Why it failed.
• Whether the issue is repairable.
• If replacement parts are available
• Whether repair or replacement is the better long-term option.
We believe homeowners deserve clear explanations, not confusing technical language or pressure to make an immediate decision.
Why Repairs Usually Require a Second Visit
Many homeowners ask why repairs aren’t always completed during the same appointment. The answer is simple—we want to repair your assembly correctly.
Backflow preventers are manufactured by different companies, such as Wilkins, Watts, and Apollo, and each model may require different internal repair kits or replacement components. Rather than installing incorrect or universal parts, we obtain the proper components designed specifically for your assembly.
Once the parts are available and you’ve approved the estimate, we’ll schedule a return visit to complete the repairs. This approach helps ensure a reliable repair and reduces the chance of future issues.
Every Repair Is Followed by Another Certified Test
Repairing a backflow preventer is only part of the process.
After the repairs are complete, the assembly must be tested again using certified testing equipment to verify that it now meets all required performance standards.
Only after passing this final test can the updated certification be submitted electronically to the appropriate jurisdiction.
This final step confirms that your backflow preventer is once again providing the protection it was designed to deliver.
Did You Know?
Many backflow preventers remain in service for years because their internal components can often be rebuilt. Replacing worn springs, seals, and other serviceable parts can restore the assembly’s performance without replacing the entire device—provided the body of the assembly is still in good condition.
Our Philosophy: Repair When It Makes Sense, Replace When It’s Necessary
At Advanced Irrigation, we don’t believe every failed test should result in a new backflow preventer. Whenever it’s safe, practical, and cost-effective, we’ll recommend repairing your existing assembly. If the device has suffered extensive damage, severe corrosion, or freeze-related cracking, we’ll explain why replacement is the better long-term investment. Our goal is to provide honest recommendations based on the actual condition of your backflow preventer—not unnecessary repairs or replacements. Whether your device needs a simple rebuild or a complete replacement, you’ll receive professional guidance, transparent communication, and quality workmanship every step of the way.
Types of Backflow Preventers We Test
Not every irrigation system uses the same type of backflow prevention assembly. The type of device installed depends on factors such as local plumbing codes, the level of hazard associated with the irrigation system, and the property’s specific requirements. At Advanced Irrigation, we perform certified testing on many of the most common backflow prevention assemblies found throughout Northern Virginia. Whether your device is protecting a residential lawn irrigation system or a commercial property, we have the knowledge and equipment to test it accurately.
Reduced Pressure Zone (RPZ) Assemblies
The Reduced Pressure Zone Assembly (RPZ) is one of the highest levels of protection used for irrigation systems. An RPZ contains two independently operating check valves separated by a pressure-monitored relief valve. If either check valve does not seal properly or pressure conditions change unexpectedly, the relief valve opens to discharge water rather than allowing contaminated water to flow backward into the drinking water system. Because of this design, RPZ assemblies provide excellent protection against both backpressure and back siphonage conditions. These assemblies are commonly installed on:
• Residential irrigation systems
• Commercial irrigation systems
• HOA common areas
• Schools
• Office buildings
• Medical facilities
• Industrial properties
Due to their complexity, RPZ assemblies require annual testing by a Certified Backflow Prevention Device Worker (Certified Backflow Tester).
Double Check Valve Assemblies (DCVA)
A Double Check Valve Assembly uses two independently operating check valves to prevent water from flowing backward into the potable water supply. Unlike an RPZ, a Double Check Assembly does not include a relief valve. Instead, protection is provided by the two internal check valves working together to stop reverse flow.
These assemblies are commonly installed where the degree of potential contamination is considered lower than systems requiring an RPZ. Although the design is simpler, annual certified testing is still necessary to verify that both internal check valves continue operating correctly.
Pressure Vacuum Breakers (PVB)
Pressure Vacuum Breakers are another common type of backflow prevention device used on irrigation systems. These assemblies are designed primarily to protect against back siphonage, which occurs when negative pressure develops in the public water system and attempts to draw water backward through the irrigation system.
A PVB contains:
• An air inlet valve
• A check valve
• Test cocks
• Shutoff valves
When operating correctly, the air inlet opens during a pressure loss, preventing contaminated water from being siphoned into the potable water supply. Like other backflow prevention devices, Pressure Vacuum Breakers require annual testing to verify proper operation.
Spill-Resistant Vacuum Breakers (SVB)
Some irrigation systems use a Spill-Resistant Vacuum Breaker. An SVB performs a similar function to a standard vacuum breaker while reducing water
discharge during operation. Although these assemblies are less common, they still require periodic inspection and testing to ensure continued protection.
Common Manufacturers We Service
Our certified testing services include many of the industry’s most trusted manufacturers. Some of the brands we commonly work with include:
• Wilkins
• Watts
• Apollo
Regardless of the manufacturer, every backflow preventer is tested according to accepted testing procedures using calibrated testing equipment.
Pro Tip from Our Certified Backflow Tester
The manufacturer of your backflow preventer doesn’t determine whether it passes or fails its annual test. Even high-quality assemblies from trusted brands like Wilkins, Watts, and Apollo require routine testing because all mechanical components experience normal wear over time.
Does the Manufacturer Matter?
Homeowners often ask if one manufacturer is “better” than another. The truth is that manufacturers like Wilkins, Watts, and Apollo all produce reliable backflow
prevention assemblies when properly installed and maintained. The most important factor isn’t necessarily the brand—it’s ensuring the device is:
• Installed correctly.
• Protected from freeze damage.
• Tested every year.
• Repaired when necessary.
• Maintained by qualified professionals.
A properly maintained backflow preventer can provide reliable protection for many years.
Why Professional Testing Is Important
Although backflow preventers may look similar from the outside, each manufacturer and model has its own design, internal components, and repair kits.
Testing these assemblies requires more than simply attaching a gauge. A certified tester must understand how each device operates, interpret the test results correctly, and determine whether the assembly meets the required performance standards. That’s why hiring a Certified Backflow Prevention Device Worker (Certified Backflow Tester) is so important. Proper testing helps ensure your device continues protecting your drinking water and that the required documentation is completed accurately.
Did You Know?
Two backflow preventers can look nearly identical from the outside but contain different internal components and require different repair kits. That’s one reason repairs are often scheduled for a second visit—using the correct parts for your specific assembly is essential to restoring proper operation.
Electronic Report Submission & County Compliance
Annual Backflow Testing and Local Compliance
Many homeowners first learn about backflow testing after receiving a reminder or notice from their local water authority. It’s common to have questions about why the test is required, who performs it, and what happens once the testing is complete.
At Advanced Irrigation, we help make the process as straightforward as possible. After your certified backflow test is completed, we electronically submit the required
information to the appropriate jurisdiction when applicable. We also provide clear communication throughout the process so you understand what has been completed and what to expect next. Our goal is to help homeowners stay compliant with local requirements while making the annual testing process simple and stress-free.
We Provide Electronic Report Submission
After successfully completing your certified backflow test, we prepare and electronically submit the required report for your jurisdiction.
The report typically includes important information such as:
• Property address
• Customer information
• Backflow preventer manufacturer
• Model number
• Serial number
• Device size
• Test results
• Pass or fail status
• Testing date
• Tester certification information
Accurate reporting is just as important as the testing itself. Complete documentation helps ensure the proper records are maintained and confirms that your annual testing requirement has been fulfilled.
You’ll Receive a Copy of Your Test Report
For many jurisdictions, your email address is included as part of the electronic submission process. This allows you to receive a copy of the completed report for your personal records. Keeping a copy of your annual test report can be helpful if you ever need to verify that testing was completed or review information about your backflow assembly in the future.
Pro Tip from Our Certified Backflow Tester
Save your annual backflow test report in a safe place. It contains valuable information about your assembly—including the manufacturer, model number, serial number, and testing history—which can be helpful if repairs or replacement are ever needed.
What If My Device Doesn’t Pass?
If your backflow preventer does not pass its annual performance test, don’t panic.
A failed test does not automatically mean you’ve done something wrong or that the entire
assembly must be replaced.
Many failures are caused by normal wear of serviceable components that can often be repaired.
If repairs are recommended, we’ll explain:
• Why the device failed
• Which components require attention
• Whether repair is possible
• Whether replacement is the better long-term solution
Once repairs are completed, the assembly is tested again before the updated certification is
submitted.
This ensures the device is operating correctly before the testing process is finalized.
