Backflow Testing in Prince George's County, MD
Nationwide Backflow Services handles backflow prevention testing, repair, replacement, and new installation across Prince George's County — all of it inside the WSSC Water service area. Because our technicians are both WSSC-registered cross-connection specialists and licensed plumbers, we can test the assembly, fix it if it fails, and file the report with WSSC in a single trip.
WSSC compliance
On WSSC water, your Prince George's County test is due every year.
Every testable assembly is tested at installation and once a year after — plus any time it's repaired, relocated, or replaced. The completed report is due within 30 business days and can only be submitted by a WSSC-registered principal master plumber. That's us.
What WSSC requires in Prince George's County
WSSC Water's code applies the same rule county-wide: every testable backflow assembly is tested at installation, once a year after that, and again after any repair, relocation, or replacement. The completed report is due to WSSC within 30 business days, and it can only be submitted by a WSSC-registered principal master plumber.
Property owners who let the annual test lapse risk a non-compliance notice from WSSC, and continued non-compliance on a health-hazard connection can escalate to enforcement. Keeping the cycle current is far cheaper than catching up under a notice.
The cross-connection office for Prince George's County is 301-206-8601. If you are not sure which assemblies on your property are on file with WSSC, we can pull that together as part of a survey.
How a test works
Four steps, and the paperwork is on us. Most single-assembly visits are wrapped up in well under an hour.
Schedule
Send the property address and roughly how many assemblies. We confirm a date — often the same week.
Test on site
A calibrated-gauge test on each assembly. Pass or fail is confirmed on the spot, with the readings recorded.
We file with WSSC
A passing report is transmitted to WSSC Water on your behalf, well inside the 30-business-day deadline.
Repair only if needed
If something fails, we quote the fix — usually same-visit — then retest and refile. Never sold work you don't need.
Assemblies we test
Reduced-pressure zone (RP / RPZ), double check (DCVA), pressure vacuum breaker (PVB), and spill-resistant vacuum breaker (SVB) — the full set of testable assemblies WSSC recognizes. Testing is done with a calibrated differential-pressure gauge, runs roughly 20–30 minutes per assembly, and needs a brief shut-off of the water line it protects.
Multi-assembly commercial sites along the Route 1, Route 301, and Central Avenue corridors are scheduled in a single visit to hold total downtime down.
Failed test? We can usually fix it the same day
Most failures are mechanical wear — checks, springs, seats, relief valves — and we carry rebuild kits for the common Watts, Febco, Zurn Wilkins, and Apollo/Conbraco assemblies. If a unit cannot be brought back to spec, we will quote a replacement sized for the hazard level. We retest and refile once the repair is done, so there is no second trip charge and no gap in your compliance record.

Common questions
Backflow testing in Prince George's County.
Can you file my WSSC backflow report for me?
Yes. We complete the field test and our registered principal master plumber transmits the report to WSSC electronically, inside the 30-business-day window. You get a copy for your records.
Who is allowed to test a backflow preventer in PG County?
A cross-connection technician registered with WSSC Water who also holds a Maryland plumbing license. Both are required to test, repair, and file — our technicians carry both.
We manage several commercial properties in the county — can you handle all of them?
Yes. We run scheduled testing programs for portfolios and campuses: one point of contact, tracked due dates, consolidated reporting, and budget planning for repairs and replacements.
How much is a backflow test in Prince George's County?
It depends on how many assemblies and what type. Send the property address and an assembly count and we will price it — the estimate is free.
What happens if we miss the annual deadline?
WSSC issues a non-compliance notice and can escalate from there. If you have fallen behind, we can usually get you tested and refiled quickly — call us and we will sort out the backlog.
