Drain Line cost — national FAQs.
Drain line vs sewer line?
Drain lines run inside the home from fixtures to the main drain. Sewer lines carry combined waste from the main drain out to the city. Sewer work is usually larger and more expensive.
Is a slab cut always necessary?
Only if the failing drain runs under slab. Branch lines in walls or crawlspaces are replaced without touching concrete.
Are these jobs covered by insurance?
Most policies do not cover wear-related drain failures. Sudden damage may be covered — check your policy.
