When Repair Won't Cut It — Full Sewer Line Replacement
Some sewer lines are past the point of spot repairs. When the camera shows damage throughout — multiple root intrusion points, extensive cracking, a bellied section where the pipe has sunk, or a line made of deteriorating Orangeburg or clay pipe — full replacement is the right call. Patching a failing line in one spot only delays the inevitable failure somewhere else.
We see this most often in pre-1970 homes throughout Murray, Midvale, Sugar House, and the Avenues. Original clay pipe joints loosen over decades as Utah's clay soil shifts seasonally, and Orangeburg pipe (a tar-impregnated cardboard product used from the 1940s–1970s) literally collapses under soil pressure. If your home was built before 1980 and you're experiencing recurring sewer problems, the camera will usually show a line that needs full replacement.
We offer two replacement methods: traditional excavation (digging a trench along the pipe path) and trenchless pipe bursting (pulling a new HDPE pipe through the old one). The right method depends on your pipe condition, property layout, and what's above the line — driveways, mature trees, or landscaping that you want to preserve.
Traditional Excavation vs. Trenchless Pipe Bursting
Traditional excavation is necessary when the line has severe bellies (the pipe has sunk and can't be followed by trenchless equipment), when there are sharp bends in the line, or when the existing pipe has completely collapsed and lost its path. We dig a trench along the old line, remove the damaged pipe, and install new Schedule 40 PVC at the correct grade. Trenchless pipe bursting works when the old pipe still has a viable path — we pull a new HDPE pipe through the old one, breaking the old pipe apart as the new one takes its place. This preserves your landscaping, driveway, and yard. Most residential pipe bursting jobs are completed in a single day.

Know the Warning Signs
Signs You Need Main Sewer Line Replacement
Catch these early to avoid a bigger, more expensive problem down the line.
Recurring Backups Despite Cleaning
If professional sewer cleaning provides only temporary relief and the line backs up again within weeks or months, the pipe itself has structural problems that cleaning can't fix.
Act NowCamera Shows Widespread Damage
Multiple cracks, root entry points at every joint, offset connections, or a bellied section mean the entire line is compromised — not just one spot.
Act NowOrangeburg or Clay Pipe in Camera Footage
Orangeburg pipe (black, fibrous-looking) and old clay pipe are at the end of their service life. If you still have these materials, replacement prevents emergency failure.
Watch ThisSewer Line Belly Visible on Camera
A belly is a low point where the pipe has sunk, creating a spot where waste and water collect. Bellies cause chronic slow drainage and are not fixable without replacing that section.
Watch ThisHome Built Before 1970
If your home is over 55 years old and you're experiencing any sewer symptoms, the original pipe materials are likely near or past their expected lifespan.
Watch ThisFoundation or Yard Settling Near Sewer Path
Soil settling along the sewer line path can indicate a long-term leak that's been washing away soil around the pipe — a sign the line is failing underground.

What Our Customers Say
“Camera showed our entire clay sewer line was cracked and root-filled — the plumber said it was one of the worst he'd seen in Sandy. Towers replaced the whole thing with PVC in two days. They handled the permit, the city inspection, and even re-graded the yard where they dug. Three years later, not a single issue.”
