Should You Outsource Backflow Testing? 6 Reasons Why Companies With Plumbers Do.

For many businesses, facility departments and plumbing contractors, outsourcing backflow testing makes more sense than maintaining the certification, equipment, scheduling and administrative systems required to perform it in-house. A specialized backflow company can handle testing, reporting, repairs and retesting while your team stays focused on its primary work.

Backflow testing can look simple from the outside: test the assembly once a year, submit the paperwork and move on.

Anyone who manages a large number of backflow assemblies knows there is considerably more to it.

There are testing deadlines to track. Assemblies have to be located and accessible. Certified testers have to be scheduled. Different water providers may have different reporting processes. Failed assemblies need to be repaired and retested. Records have to make it to the right place.

For a plumbing contractor, property manager, facility department or multi-site organization, backflow can quietly become an entire compliance program.

That's why many organizations choose to outsource it.

It's essentially adding backflow capability without adding an entire backflow department.

What Does It Mean to Outsource Backflow Testing?

Outsourcing backflow testing means using a specialized backflow company to manage some or all of the testing and compliance work instead of maintaining those capabilities internally.

Depending on the organization, that can include:

• Annual backflow assembly testing

• Scheduling and access coordination

• Water-provider reporting

• Tracking multiple locations and assemblies

• Diagnosing failed assemblies

• Backflow repair

• Retesting after repair

• Backflow assembly replacement and installation

For plumbing companies, the backflow provider may essentially function as a backflow subcontractor or extension of the service department. For facility and property management teams, the provider can become a single point of contact for backflow compliance across multiple properties.

1. Backflow Testing in Washington Requires a Certified Tester

Backflow testing is a specialty within the plumbing and water industry. Washington regulations require approved backflow prevention assemblies protecting the public water system to be tested by a certified Backflow Assembly Tester (BAT). Testing is required when assemblies are installed, repaired, reinstalled or relocated, after a backflow incident, and annually thereafter. A water purveyor can require more frequent testing in certain circumstances. That distinction matters.

A skilled plumber or maintenance technician isn't automatically qualified to perform the required backflow test. Maintaining an in-house program means maintaining the necessary BAT certification as well as the equipment and processes that go with it.

If backflow isn't a core part of your business, outsourcing gives you access to that specialty without having to build it yourself.

2. Your Plumbers and Maintenance Staff Can Stay Focused on Their Actual Work

This is one of the biggest reasons to outsource backflow — and one that is easy to overlook. A licensed plumber may be capable of becoming a certified backflow tester.

The better question is: Is annual backflow testing the best use of that plumber's time?

Testing requires more than time at the assembly. There is travel, scheduling, site access, locating equipment, documentation and reporting. Meanwhile, that same employee could be handling leaks, water heaters, service calls, tenant improvements, plumbing repairs or other work that requires their broader skill set. The same principle applies to facility personnel.

Instead of asking an already-busy maintenance department to build another specialty compliance function, a backflow provider can handle it.

3. The Administrative Work Can Take Longer Than the Test

This is the part of backflow compliance that doesn't get much attention. The field test is only one step.

Depending on the property and water provider, someone may also need to determine:

• Which assemblies are due

• Where each assembly is located

• Which water provider has jurisdiction

• What the testing deadline is

• Whether an appointment or site access is required

• Whether the assembly passed

• Whether repairs are needed

• Whether a retest has been completed

• Where the test report must be submitted

• Whether the water provider has received or accepted it

Multiply that across dozens — or hundreds — of assemblies, and backflow becomes a significant administrative responsibility. A specialized backflow testing company already has systems built around that workflow.

That can be particularly valuable for organizations with properties served by multiple Washington water districts, municipalities and water providers.

4. Failed Backflow Assemblies Can Move Straight Into Repair and Retesting

A failed backflow test creates another decision point.

Who diagnoses the problem?

Who obtains the correct repair parts?

Who performs the repair?

Who schedules the retest?

And who makes sure the passing result gets submitted afterward?

Using separate vendors for each stage can turn one failed assembly into several phone calls, work orders and site visits. A backflow company that performs both testing and repair can often move directly from identifying the failure to recommending the appropriate repair, completing the work and retesting the assembly. There is also value in repetition. Technicians who work primarily on backflow assemblies see a wide range of manufacturers, models, sizes, installations and failure conditions. That experience can be useful when an assembly doesn't behave exactly as expected.

5. Multi-Site Backflow Compliance Becomes Much Easier to Manage

One assembly is relatively easy to track. One hundred assemblies across 30 properties and several water-provider jurisdictions is a different operation entirely.

This is particularly relevant for:

• Property management companies

• Restaurant groups

• Retail chains

• Healthcare organizations

• School districts

• HOAs and multifamily properties

• Commercial and industrial facilities

• Municipalities

• Companies with multiple Washington locations

At that scale, the value of outsourcing isn't simply having someone perform the annual tests. It's having someone help manage the portfolio.

As a specialized provider of backflow testing services, Certified Backflow Testing organizes testing geographically, coordinate access, identify failures, complete repairs and provide one point of contact instead of requiring the facility team to manage each assembly individually.

6. Plumbing Contractors Can Offer Backflow Service Without Building a Backflow Department

Backflow presents an interesting challenge for commercial plumbing contractors.

A customer asks: "Can you take care of our backflow testing too?" You want to say yes. But building that service internally means certified testers, test equipment, calibration, scheduling, reporting procedures, repair inventory and enough testing volume to justify all of it.

There is another option: Partner with a company that specializes in backflow.

A dedicated backflow subcontractor can provide testing and repair support while allowing the plumbing contractor to maintain the broader customer relationship.

It's essentially adding backflow capability without adding an entire backflow department.

For contractors that occasionally encounter backflow work — or that manage large commercial customers with annual testing requirements — that can be a much more efficient model.

When Does Outsourcing Backflow Testing Make the Most Sense?

Outsourcing tends to provide the greatest value when an organization:

Situation	Why Outsourcing Helps
Has multiple properties	One provider can coordinate testing across locations
Has many backflow assemblies	Centralized tracking reduces administrative work
Operates in several water-provider jurisdictions	A specialist can manage varying reporting requirements
Doesn't have a certified BAT on staff	No need to build an internal testing program
Uses plumbers for testing	Keeps skilled plumbers available for broader plumbing work
Experiences frequent failed tests	Testing, repair and retesting can stay with one provider
Is a plumbing contractor	Adds backflow capability without creating a dedicated department
Has annual compliance deadlines	Provides an accountable point of contact for completing the work

Is Outsourcing Backflow Testing Right for Every Organization?

Not necessarily. A large organization with several certified testers, significant annual testing volume and an established compliance system may have good reasons to keep the work in-house.

But for many organizations, the real calculation isn't simply: "What does a backflow test cost?" It's: "What does it cost us to maintain the people, equipment, scheduling, reporting, repair capabilities and administrative systems necessary to manage this ourselves?" That's a much more useful comparison.

Frequently Asked Questions About Outsourcing Backflow Testing

Can a regular plumber perform a backflow test in Washington?

Not solely by virtue of being a plumber. Backflow prevention assemblies that protect the public water system must be tested by a Washington-certified Backflow Assembly Tester (BAT). Some plumbers also hold BAT certification, but the credentials are separate.

How often do backflow assemblies need to be tested in Washington?

Approved backflow assemblies protecting the public water system are generally tested when installed, repaired, reinstalled or relocated and annually thereafter. Water providers may require more frequent testing in certain situations.

Can a company outsource both backflow testing and repairs?

Yes. Using one provider for testing, repair and retesting can simplify the process when an assembly fails because the same company can take the work from the initial test through a final passing test.

Can plumbing contractors subcontract backflow testing?

Yes. A plumbing contractor can partner with a backflow testing company when customers require annual testing or backflow-specific work. This allows the contractor to provide a broader solution without necessarily maintaining its own backflow testing department.

Who submits the backflow test results to the water provider?

Requirements vary by water provider. As your full-service backflow testing company Certified Backflow Testing handles the submission of the completed test report to the appropriate water provider as part of our service.

Is outsourcing backflow testing useful for companies with multiple locations?

It can be especially useful for multi-site organizations. As a single backflow provider Certified Backflow Testing routinely helps coordinate testing schedules, locations, failures, repairs, retests and reporting across an entire portfolio rather than requiring facility staff to manage each assembly separately.
