Commercial Backflow Testing
Commercial backflow testing and certification across the DMV. Serving DC, Maryland, and Virginia from Suitland, MD.
If your commercial property has backflow prevention assemblies, and nearly all do, most DMV jurisdictions require them tested annually by a certified tester, with the results filed. Miss the deadline and the letters start, followed by fines and, eventually, water service action.
We test, repair, and certify commercial backflow assemblies across the DC metro, ASSE-certified (59027), with the county paperwork handled as part of the service.
What commercial testing covers
A backflow test verifies the assembly actually stops reverse flow under the conditions it exists for. It is a gauge-and-procedure test with pass-fail results, not a visual once-over.
- Annual certification tests on RPZ and double-check assemblies
- Test reports filed with the county and water authority
- Failed assemblies repaired and retested, often same visit
- Fire line, irrigation, and domestic assembly testing
- Reminders before your next test window closes
What to expect on the day
When we arrive, the first thing we do is listen and look, because the visible symptom is not always the real problem. We diagnose the actual cause, explain it to you in plain language, and give you an honest price before any work starts. You approve it, and only then do we begin. When the work is done, we test it, walk you through what we did, and leave the space clean. That is the same process on every job, whether it is a small repair or a major replacement.
Whatever the job, you get one licensed Master Plumber from start to finish, an honest price before we begin, and a plumber who cleans up after himself. Ready to get it handled? Request a free quote or call us at any hour. Want to see the kind of work we do? Take a look at our recent projects.
Test, repair, and file: one call
The annoying part of backflow compliance is rarely the test, it is the logistics: knowing the deadline, getting a certified tester, handling a failure, and making sure the paperwork actually reached the county. We do the whole loop.
When an assembly fails, we repair it and retest immediately whenever parts allow, so one visit ends with you compliant instead of scheduling a second one.
- ASSE 59027 certified testing
- Failures repaired and retested promptly
- County filing handled, deadlines tracked
Why the DMV calls Jackson Plumbing
There are plenty of plumbers in the Washington metro. What sets us apart is not a slogan, it is how the work actually gets done. When you call, a real person picks up, 24 hours a day. When we come out, we give you a real arrival window instead of a vague promise to show up sometime. And when we diagnose the problem, we put an honest price on it before we touch anything, so there are never surprise line items on the invoice.
Brandon Jackson has spent nearly three decades in this trade, and he built the business around a simple idea: treat people the way you would want to be treated in your own home. That means explaining what is wrong in plain language, giving you honest options instead of the most expensive one, and leaving the space cleaner than we found it. It is why so much of our work comes from repeat customers and neighbor-to-neighbor referrals across DC, Maryland, and Virginia.
We are a licensed Master Plumber, license PLM40000116, fully credentialed in Maryland (109495), Virginia (2710083375), and with WSSC (P-83640), plus ASSE certification and a BBB A-rating. That licensing matters: the code-sensitive work, the permitting, and the connections all get done right, so your plumbing passes inspection and holds up for years. Whether the job at your home is a quick repair or a major replacement, you get the same experienced plumber and the same honest standard.
It also means we stand behind what we do. If something we installed or repaired ever acts up, you call us and we come back, because our reputation across the DMV is worth more than any single invoice. That is the difference between a plumber who is here today and a plumber who has spent nearly thirty years building a name he intends to keep. We would rather do one job right and earn a customer for the next twenty years than rush through three and lose all of them.
Honest pricing, no hidden fees
The part people dread most about calling a plumber is the bill, because too many outfits hide fees, pad the invoice, or quote one number and charge another. We do not work that way. You get a clear, honest price before any work begins, and that is the price you pay. No surprise line items, no mystery charges, no upsell to the most expensive option when a simpler fix will do. If we think a repair will hold, we tell you, even when a replacement would earn us more. That kind of straight dealing is rare in this trade, and it is exactly why our customers keep calling and keep referring their neighbors. When you are ready to get it handled, call (202) 840-1998 any hour, or tell us what is going on and Brandon will get right back to you.

How often does commercial backflow testing have to happen?
Annually in most DMV jurisdictions, and some water authorities require it more often for high-hazard assemblies. We track your deadline so the notice never becomes a fine.
What happens if an assembly fails the test?
It gets repaired and retested. Common failures, worn check valves and relief valve issues, are repairable on the spot in most cases, and you leave the visit compliant.
Do you file the paperwork?
Yes. Test results go to the county or water authority as required, and you get copies for your records. Compliance is not real until the filing is.
Which assemblies on our property need testing?
Typically every testable assembly: domestic service protection, irrigation, and fire line assemblies. We inventory what your property has on the first visit.
Are you certified for this work?
Yes. Backflow testing requires specific certification, ours is ASSE 59027, alongside our Master Plumber license and WSSC credentials.
