Backflow Testing in Bladensburg, MD

Bladensburg's water and sewer come from WSSC Water, which requires every testable backflow assembly, such as irrigation vacuum breakers, RPZs and some residential fire sprinkler double checks, to be tested yearly and after installation or repair. WSSC doesn't test devices itself; a WSSC-registered plumber with cross-connection certification does. Call the number on this page to be connected with a local plumber in Bladensburg.

What happens when you call

The call connects you with an independent plumber who works in Bladensburg. Expect to describe the property, the device and what it protects. Shops, restaurants and auto businesses at the crossroads of US 1 Alternate, MD 201 and MD 450 often have assemblies on their service lines, while houses in Decatur Heights or Sunnybrook may have one only on a sprinkler system or boiler. On the visit, the plumber isolates the device, runs the gauge test and records the result. A failed device is usually rebuilt and retested the same day if parts are on the truck.

Bladensburg conditions

Bladensburg is a historic Anacostia River town just outside the District, and its median home was built in 1968. Houses of that age were not built with backflow assemblies, so most homeowners only deal with them after adding irrigation, a fire sprinkler line or a treated boiler. WSSC still expects every testable device to be tested yearly once it exists.

The Town of Bladensburg's website covers business licenses rather than building or plumbing permits. Plumbing permits and inspections here come from WSSC, which also permits all natural gas and LP gas work in the county. The county's cross-connection line is 301-206-8601.

WSSC's tap water reports show Potomac plant water averaging about 140 mg/L of hardness and Patuxent plant water about 65 mg/L, and which plant serves a given address isn't spelled out. Over years, mineral buildup on check seats is one reason an older device starts weeping or fails a test. WSSC also publishes an address lookup map of service line material, worth checking while you're thinking about the water line into an older house.

Locate the assembly and the shutoff that feeds it
Have any WSSC letter or account number ready

Backflow Testing questions in Bladensburg

Does an ordinary house need a yearly backflow test?

Usually not. Most older Bladensburg homes have no testable device. The yearly test applies when there is one, typically on irrigation, a fire sprinkler line or a treated boiler.

Why is water dripping or spitting from my backflow device?

Constant water from an RPZ relief port points to a check that won't seal or a worn relief valve, often from debris or mineral buildup. It needs service, but the discharge shows the device is protecting the line.

Who is allowed to test my backflow assembly?

A WSSC-registered plumber who is also a certified cross-connection technician. WSSC doesn't send its own testers.

Can a winter freeze damage an outdoor backflow preventer?

Yes. An outdoor assembly that holds water through a freeze can crack. Drain it in the fall or protect it with an insulated cover.
