Aging underground sewer pipes can cause severe backup issues when bellies develop or joints degrade over time. Replacing failing lines with modern SDR pipe restores proper gravity drainage and protects home interiors from hazardous plumbing backups.
In Clifton Park, NY, a residential property suffered from frequent drain backups caused by a deteriorating 1950s sewer lateral. Duell Plumbing & Heating executed a 13-hour sewer lateral excavation and line replacement to permanently fix the drainage system.
Key Takeaways
- THE CHALLENGEAn old asbestos sewer pipe developed bellies that prevented proper gravity-fed drainage.
- THE APPLICATIONExcavated 80 feet to install an SDR gasketed drain line with exterior cleanouts.
- THE RESULTRestored proper waste flow and tied directly into the municipal sewer manhole.
A camera inspection revealed that the original 1950s asbestos line had sagged, causing waste to pool in low spots rather than flow into the municipal system. Replacing the 80-foot lateral restored continuous gravity flow and added exterior access for future maintenance.

| Key Outcome: |
Completely eliminated line bellies and connected directly to the municipal manhole in a 13-hour project. |
Diagnosing Sewer Backups with Camera Inspection
The project began when the homeowner reported recurring backups in the house. Drains were cleared using cable machines, followed by a sewer camera inspection to evaluate the underground pipe condition.
The video inspection revealed significant bellies in the original 1950s asbestos-based line. Because gravity sewer systems rely on a continuous downward slope, these dips allowed water and waste to pool, creating chronic blockages.
Excavating and Replacing the Sewer Lateral
Before digging, the team contacted 811 to locate underground utilities, including gas, electric, and cable lines. The 13-hour project involved excavating 80 feet from the foundation out to the street.
Technicians connected modern SDR gasketed pipe to the existing foundation outlet and tied the new lateral directly into the town sewer manhole.
As part of the project, the Duell Plumbing team added an outside cleanout pipe, a capped, vertical access point that connects to a home's main sewer line.
"By code now, we have to add outside cleanouts. This is good for our customers because if they get a backup, we don't have to enter the house to remove the clog." - (Jared, Duell Plumbing & Heating)
The team then coordinated with a paving contractor who was installing a new driveway for the homeowner.
Long-Term Reliability and Driveway Coordination
Replacing the underground lateral permanently resolved the drainage issues, ensuring waste flows smoothly without lingering in dips in the pipe.
By adding exterior cleanouts and working with the driveway paving crew, the job was completed cleanly, giving the homeowner lasting protection and convenient exterior maintenance access.

Frequently Asked Questions
What causes sewer pipe bellies in Clifton Park properties?
Sewer pipe bellies occur when the soil beneath an underground pipe settles or shifts over time. This creates a sag where water and waste gather, preventing proper gravity drainage and causing frequent backups.
Why are exterior sewer cleanouts important?
Exterior cleanouts provide direct ground-level access to your main sewer line. If a blockage ever occurs, technicians can clear the main line from outside without bringing heavy drain cleaning equipment inside your home.
How do technicians ensure safety during deep sewer excavation?
Prior to digging, 811 is called to mark all underground public utilities. For excavations deeper than eight feet, technicians utilize shoring systems to protect workers and prevent trench wall cave-ins.
