Sewer Line Materials & Brands in Great Falls, MT
We work with a variety of proven sewer line materials and trusted brands for durability and performance. Options include PVC (polyvinyl chloride) for its corrosion resistance, ABS (acrylonitrile butadiene styrene) for its strength, and sometimes modern cast iron for specific applications. We source our pipe from reputable manufacturers that meet industry standards. Rocky ground, clay and gravel are all common in Montana, and rock can make trenching for sewer and water lines slow and expensive. Our team helps you choose the best material for your specific needs and budget.

Sewer Line Material Upgrades in Great Falls
Many older homes in Great Falls may have sewer lines made from outdated materials like clay or cast iron, which are prone to cracking, corrosion, and root invasion. We offer upgrades to modern, more durable materials such as PVC or HDPE (high-density polyethylene). These materials resist corrosion, roots, and shifting soil, giving your sewer system a much longer lifespan.
Trenchless Pipe Bursting in Great Falls
Pipe bursting replaces the old sewer line by pulling a new pipe through the path of the old one. A bursting head breaks the old pipe outward while fused HDPE pipe follows close behind. This usually needs only an entry pit and an exit pit instead of a long trench. It works well under driveways, mature trees and landscaping. The new pipe is seamless, which leaves no seams for roots to enter.
Preventative Measures After Replacement in Great Falls
Once your sewer line is replaced, we can recommend steps to extend its lifespan. This includes landscaping choices that won't interfere with your new pipes, proper waste disposal habits, and periodic inspections. Rocky ground, clay and gravel are all common in Montana, and rock can make trenching for sewer and water lines slow and expensive. We also talk through how trees and soil movement near your home can affect the line and what you can do to reduce future risks. That keeps your new system in Great Falls problem-free.
Open-Trench Sewer Replacement in Great Falls, MT
Traditional excavation is sometimes the best option, especially when the old line has a severe belly or the slope must be corrected. We dig along the line, remove the old pipe and set new PVC on compacted bedding at the correct grade. Rocky or hard-packed soil can slow digging, and we plan for that in the estimate. Each joint is glued and checked before backfill. The inspector sees the open trench before we cover it.
Permitting and Code Compliance in Great Falls, MT
Sewer line replacement projects in Great Falls, MT often require permits and must comply with local plumbing codes. DFV Plumbing handles the permitting process and makes sure every part of the replacement meets or exceeds municipal standards. Our knowledge of local regulations means your new sewer line is installed correctly and safely. That helps you avoid potential fines or future issues.
Cast Iron Sewer Replacement in Great Falls
Cast iron drains in older homes corrode from the inside, particularly along the bottom of the pipe. Over time this leaves cracks, holes and a rough surface that catches waste. Replacing the cast iron sewer outside the home is often the first step. We can also evaluate under-slab cast iron and discuss lining or rerouting choices. New PVC or HDPE will not rust or scale the same way.

Clay and Orangeburg Line Replacement in Great Falls, MT
Clay pipe joints let roots in, and Orangeburg fiber pipe flattens and blisters with age. Both are near the end of their service life in many older properties. When the camera shows multiple failures, replacement is typically the best value. We remove or burst the old line and install modern pipe with a long expected service life. You get a smooth, root-resistant line to the street.
