"Frank and his team at Kozan did an absolutely incredible job on my house replumb! We had to replace our 1980s polybutylene pipes as they were finally starting to leak, and knew it would be an invasive job. I had 5 companies come out and quote me - Kozan came in the most reasonable, but that wasn't the only reason I went with them. When Frank was here doing his estimate, he was the only guy who really looked at the pipes, and started putting together a plan; having worked construction myself, this is exactly what I would've done. All the others were in and out with a handshake and a couple pics. Regarding the work, they replumbed the house with minor intrusion, and even took care to cut the drywall stud-to-stud to make my patchwork a bit easier. They did everything they could to keep the water running to all the lines not being worked on, and cleaned everything up every day before they left. All-in-all the job was very well done, and Frank was a true professional. Thanks Frank!"

"The technician, Marvin, could not have been more professional, knowledgeable and efficient. The main issue we wished to resolve was changing the shower. Marvin communicated the process involved, project pricing and returned on the second day with necessary parts to complete the job. The entire experience working with him was seamless and was a great way to start 2026!"

FAQs for sewer main install, replace or repair projects in Washington DC, DC

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
