Sewer Line Repair in Chantilly, VA

Do I call Fairfax County or a plumber when the sewer backs up?

Fairfax County says that if sewage backs up while no fixtures are in use, call it first at 703-323-1211 so crews can check the public main. If the main is flowing, the blockage is in the private lateral and that's the owner's to fix. In most Chantilly homes, a backup that shows up during normal use, with water rising in a basement shower or floor drain, is a private-line problem and a plumber is the faster route. The County also doesn't locate or mark private laterals, so the plumber's camera and locator will be how the line is traced.

My house isn't that old. Why would the lateral fail?

Chantilly is an outer suburb about 22 miles west of Washington, centered on the Route 50 and Route 28 interchange, with neighborhoods such as Franklin Farm and Greenbriar. The median home was built in 1987, so most laterals are plastic. Plastic doesn't corrode, but it can still fail. The trench under it can settle and create a belly where waste collects. A joint can be pulled apart when a deck, patio or addition goes in. Pipe under a driveway can crack, and roots from yard trees can still find a loose fitting. Older homes in the area may have clay or cast iron sections that are wearing out.

Can it be fixed without tearing up the yard?

Often, yes. If the camera shows cracks or a separated joint in pipe that still holds its slope, a cured-in-place liner can be installed through a cleanout, or the plumber can open one small pit at the bad spot. A sag or a collapsed section usually means digging and replacing that piece. Permits for repaired or relocated plumbing come from Fairfax County Land Development Services through PLUS, and the plumber typically files them. Common clues it's time to call:

• Gurgling from a toilet when the tub drains
• Water in the lowest drain after laundry
• Sewage odor outdoors near the cleanout
• Recurring main line clogs

A local note

Chantilly has many townhouse and association neighborhoods. If yours is one, check your community documents before work begins to confirm which section of pipe is yours and what the association expects for restoring common areas.
