Plumbing in Fairfax, VA: what local homeowners should know

Fairfax-area homes are mostly 1960s–1990s split-levels, colonials and townhomes, with many original systems now 30 to 50 years old. Older homes in Fairfax may still have galvanized supply lines, cast-iron drains or clay sewer laterals that can be scoped with a camera before deciding on repairs. Tree roots in sewer lines are a common cause of backups here.
