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
You get a real arrival window when you call, and we keep it. Once we are in the door, Brandon does not rush to a quick fix. Quality over quantity is how he runs the business, so he takes the time to track down the cause instead of treating a symptom that comes back next month. You hear the diagnosis and the price, and you give the go-ahead before any tools come out. When the job is finished, we test it, tell you what we did, and sweep up behind ourselves.
One licensed Master Plumber handles your job from the first look to the last test, and the price is set before anything starts. If that is the kind of plumber you have been looking for, send us a note about the problem or call any hour of the day. You can also browse photos of jobs we have finished to see the work for yourself.
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
Our motto is no job too big, no job too small, and we mean both halves of it. We come out for a running toilet with the same care we bring to a sewer line replacement or a commercial restroom. Every job gets a real person on the phone at any hour and an honest price before we start. A small call is often how a long relationship with a customer starts.
Brandon’s career started at 16, working alongside his uncle. He has spent nearly three decades in the trade since, and the lessons from those first years still run the shop: listen before you pick up a tool, and tell people the truth about what they need. He leaves the work area cleaner than he found it, too. A lot of our work today comes from customers who have called us before.
Brandon holds Master Plumber license PLM40000116. He is also credentialed in Maryland (109495), Virginia (2710083375), and with WSSC (P-83640), ASSE certified, and A-rated by the BBB. For your home or building, that means the jobs where mistakes are expensive, like gas lines, backflow devices, and water heater installs, are handled by someone fully qualified to do them, whether it is a quick repair or a full replacement.
When the owner is the plumber, there is nobody else to blame if a repair fails. Brandon knows that, and it is why he stands behind everything we touch. If a part we put in or a joint we made ever causes a problem, you call and we come back. That trust took years to earn, and he is not going to trade it for a shortcut on your job.
Honest pricing, no hidden fees
A plumbing bill stings most when the problem hit at a bad hour and you had no time to shop around. Some companies count on that. We price a burst pipe at two in the morning the same honest way we price a scheduled repair: Brandon looks at it, tells you what it needs, gives you the number, and waits for your okay before he starts. You are not signing a blank check because there is water on the floor. If shutting off the water buys you time to think it over until morning, we will tell you that too. The price you approve is the price on the invoice. Call (202) 840-1998 any hour, or send us a message if it can wait, and Brandon will get right back to you.

M. Owens JonesGoogle ReviewsStraight Answers
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.
