A backflow certification course is the training class behind a tester credential — some programs call it a backflow certification class, backflow prevention course or backflow testing course.
In the programs we verified, classes run 32 to 40 hours and center on field-testing backflow prevention assemblies; the routes that publish a hands-on format require wet-lab or practical-exam work.
Tuition is set by each provider; the one fixed fee we confirmed is Texas's $111 application fee.
Course length and content
A backflow certification course is the required training behind the tester credential, and its length is set by the program that will accept it, not by the school teaching it.
In the programs we verified, the approved course is 40 hours — Texas's TCEQ-approved course for its Backflow Prevention Assembly Tester (BPAT) licence, the course required for ASSE 5110 certification, and Louisiana's 40-hour tester certification for its Water Supply Protection Specialist endorsement.
Two states we verified land at 32 hours: Virginia requires a minimum of 32 hours of training at a board-approved school for its backflow prevention device workers, and Maryland requires 32 hours of backflow prevention device testing training for its journey plumber licence.
Virginia also runs a shorter 16-hour track for candidates with seven or more years of experience.
| Program | Course hours required |
|---|---|
| Texas BPAT (TCEQ-approved course) | 40 hours |
| ASSE 5110 training course | 40 hours |
| Louisiana Water Supply Protection Specialist endorsement | 40 hours |
| Virginia backflow prevention device worker (board-approved school) | 32 hours (16 with 7+ years of experience) |
| Maryland journey plumber (backflow testing training) | 32 hours |
As for content, the course exists to prepare you for the work the credential covers — in Texas, testing and repairing backflow prevention assemblies — and for the exams that gate it.
Where the exam structure is published — Texas's BPAT and ASSE 5110 — the credential is gated by two exams: a written exam, which Texas candidates take at a TCEQ-approved computer-based testing centre, and a practical exam, given by the training provider for the Texas BPAT and hands-on on four assembly types (RP, DC, PVB and SVB) for ASSE 5110.
The USC Foundation for Cross-Connection Control and Hydraulic Research (FCCCHR) runs its tester course as a series of lectures followed by guided exercises in a wet lab, aimed at field-testing backflow prevention assemblies.
The experience rules that sit around the course — Texas asks for two years of approved experience, ASSE 5110 for five — belong to the credential, not the class.
Our backflow tester certification guide covers eligibility and the certifying bodies in full.
Hands-on test-kit practice
Hands-on work is where the routes differ, and where the buying questions concentrate.
The requirements we could verify sit in the course or the exam: Virginia requires its 32-hour training to include a wet lab, with ASSE testing standards applying, and the USC FCCCHR course pairs its lectures with guided wet-lab exercises.
The exams then test the skill directly — the ASSE 5110 practical covers four assembly types (RP, DC, PVB and SVB), and the Texas BPAT practical is given by the training provider, so the school you enroll with is also the outfit that examines you.
Louisiana and Maryland publish hour totals, not course breakdowns, so ask any provider you are considering how the hours split between lecture and lab.
Hands-on practice stays part of the picture after the class, which tells you how the field treats the skill.
Texas BPAT licences are valid three years and renew with 24 hours of continuing education, 8 of which must be hands-on practical training.
ASSE certifications renew every three years through a recertification class of at least 8 hours plus written and hands-on practical exams.
When you compare classes, ask two questions about the practice time.
How are the wet-lab hours structured — how much supervised time on test kits and assemblies, versus lecture?
And which field-test procedure does the class teach?
ASSE tests to several published procedures — the USC 10th Edition, ASSE, EPA, Illinois, Missouri, one-hose and TREEO procedures are on its list — and some jurisdictions require a specific one.
A class matched to your jurisdiction's procedure is the better buy.
What a backflow certification class costs
The honest answer on cost: tuition is set by each approved provider, and our research confirmed no published tuition figures for any of these courses.
Treat every price as provider-specific — ask the school, and the program that will accept your certificate, for current numbers before you pay.
The one fixed, published number we verified is on the licence side: Texas charges a $111 application fee for the BPAT licence, submitted to the TCEQ, separate from whatever the course costs.
The state exam split matters for your budget too — the written exam runs at a TCEQ-approved computer-based testing centre while the practical is given by the training provider, so provider fees do not stop at tuition.
Fee structures differ elsewhere: Arkansas's plumbing exam instructions list no state fee for its Assembly Testing Technician credential, while Virginia's route prices out in required hours at a board-approved school.
Budget past the class as well.
Texas BPAT holders renew every three years with 24 CE hours (8 hands-on), and ASSE testers recertify every three years with at least an 8-hour class plus written and practical exams — each program sets its own fees for those.
And before you spend, it is fair to weigh the class against what the credential earns: our backflow tester career and pay guide has that picture.
Where to take a backflow certification class
Start with the program, not the provider: the agency, board or water purveyor that will accept your credential decides which class counts.
Texas requires a TCEQ-approved course for the BPAT licence.
Virginia requires training at a school approved by its board.
Louisiana's plumbing board accepts tester certifications issued by ASSE or ABPA, so an ASSE- or ABPA-recognized course is the route to its endorsement.
Maryland builds its 32-hour backflow training requirement into the journey plumber licence itself.
For the ASSE route, courses run at more than 100 ASSE-approved schools across the country.
The USC FCCCHR also runs its own tester training course — lectures plus wet-lab exercises — through the university's Foundation for Cross-Connection Control and Hydraulic Research.
Beyond the approved lists, do not assume a provider counts: if your water purveyor or code authority keeps its own tester program, its approved list governs.
A short order of operations before you enroll: confirm the approved-course list with the program that requires the credential; check that the class teaches your jurisdiction's required field-test procedure; and ask how the wet-lab hours and the practical exam are run — in Texas, remember, your provider is also your practical examiner.
Once the class, the exams and the credential are behind you, the backflow tester jobs on HVACHires are where it all goes to work.
Career information, not legal advice — course, certification and licensing requirements are set by your state agency or licensing board, or by the local water purveyor. Confirm the current rules with the authority in your jurisdiction before you enroll.
The class only counts if the program approves it
