Questions

Sewer line replacement, answered.

Answers from licensed plumbers and septic installers. Still unsure? Call West CT at (860) 248-6262.

How much does sewer line replacement cost in Connecticut?

Up to 50 feet of new sewer pipe at less than 4 feet deep starts from $6,460 at Drainworks, including a camera inspection of the remaining line, the permit and a 5-year warranty.

Repair or replace?

If the damage is in one spot, a repair is cheaper. If the pipe is failing along its length, replacement lasts longer. A camera inspection tells us which.

Can I finance a sewer replacement?

Yes. Sewer replacements are eligible for financing through Service Finance and TURNS, subject to credit approval.

What warranty do I get?

Full sewer or water line replacements carry a 5-year parts and labor warranty. Septic inlet replacements carry 3 years.
