Lorton's homes and water

Lorton runs along I-95 and Route 1 between Fort Belvoir and the Occoquan River, and the area around the former reformatory is now Laurel Hill. Most houses date from the 1990s and 2000s, with older homes scattered toward Newington and Mason Neck. Fairfax Water supplies the area, and its Griffith plant, which treats Occoquan Reservoir water, is near Lorton. Results from that plant show total hardness of roughly 77 to 147 mg/L, enough to leave scale on fittings over time. Fairfax Water owns the service line through the meter, and everything after the meter is the owner's.

What to do now

Stop active water. If a line is leaking, close the main shutoff and catch what you can.
Check the age of the house. Older homes are more likely to need a full repipe; newer ones usually need a targeted fix.
Identify the material. Note what's at the water heater and under sinks, including any printed markings on plastic pipe.
Look for a pattern. Are leaks on the pipe, at fittings or at fixture connections?
Check warranties. In homes built in the last decade or two, some pipe or fitting failures may be covered.
Ask for options. Have the plumber price a repair and a partial repipe before a full one.

Fairfax County Land Development Services issues building and trade permits for Lorton through PLUS, and the plumber usually handles the application. In older homes toward Newington and Mason Neck, ask whether any original copper or steel remains hidden in walls, since a partial repipe that ties new pipe into old lines can leave the next leak waiting just past the new work.

Repiping questions in Lorton

Why would a fairly new house need new supply pipe?

Most Lorton homes date from the 1990s and 2000s, so age alone rarely calls for a repipe. Repeated fitting failures, freeze damage or a defective product are the usual reasons.

Does the hardness of the water matter for new pipe?

Lorton's water comes largely from Fairfax Water's nearby Griffith plant on the Occoquan, where hardness runs roughly 77 to 147 mg/L. That builds some scale on valves and fittings over time.

Is a partial repipe ever enough?

Often, in Lorton's newer homes. If failures are limited to one area or one fitting type, a partial repipe or targeted repair may be enough; older homes are more likely to need a full job.

Does a whole-house repipe need a permit here?

Usually. Lorton is unincorporated, so Fairfax County Land Development Services issues building and trade permits through its PLUS system.
