Lorton's housing is mostly newer, with the 2000s its biggest building decade, so clogs there usually come from what went down the drain rather than failing pipe. A plumber can clear the line and tell you whether the problem was a fixture branch or the main. Call the number on this page to be connected with a local plumber in Lorton.

Lorton in brief
Lorton sits in southern Fairfax County along I-95 and Route 1, between Fort Belvoir and the Occoquan River. Only about 17% of homes in ZIP 22079 predate 1980, and much of the area, including neighborhoods such as Laurel Hill, was built in the 2000s. Fairfax County runs the sewer, and its Noman M. Cole, Jr. Water Recycling Facility, the County's wastewater treatment plant, is in Lorton. Maintaining the private lateral from your house to the county sewer is the owner's responsibility.
What to do now
- Stop using water if two or more drains are slow or the lowest drain is filling.
- If sewage backs up while nothing is running, call Fairfax County's 24-hour line at 703-323-1211 so crews can check the main.
- Locate the cleanout, usually a capped pipe in the basement or by the foundation.
- Move rugs and stored items away from the floor drain.
- Keep children and pets away from any wastewater.
- Write down what was flushed or poured recently; it helps the plumber pick the right tool.

Older homes on Mason Neck and near Route 1 are where a plumber is likelier to meet cast iron or clay. Clearing a clog is service work; replacing a damaged section goes through Fairfax County Land Development Services. When you call, you are connected with an independent plumber who serves Lorton. If you are not sure who maintains which part of the line, the plumber can trace your lateral with a camera once it is clear.
