Trenchless Sewer Repair
Luckily, traditional sewer repair isn’t always necessary when there’s a problem with the sewer line. Trenchless sewer repair doesn’t require any digging at all! Instead, the expert inserts a special, small camera into the sewer line to inspect the inner walls of the pipe. This means no digging up yards, cracked driveways or ruined parking lots. Using live cam footage provided by the camera, the technician identifies the problem in the sewer line.
Once the problem is identified, the plumber knows how to fix it. If the line is blocked by debris or tree roots, we use a hydrojetter to clear it out. If the pipe is ruptured, we can re-line it with a resin substance called “cured in place pipe,” or CIPP. CIPP can be inserted directly into the old pipe, where it will cure and harden, forming a new, unbroken pipe. If the whole length of piping needs to be replaced, we can use a process called “pipe bursting” to pull a new pipe through the old one. As the new pipe enters the old pipe, the old pipe “bursts” to make room for the new one.
Trenchless sewer repair is faster, less invasive, and usually cheaper than traditional sewer repair, but it may not be feasible in all circumstances.
How Do Sewer Lines Become Damaged?
Your main sewer line runs under the ground beneath your house and yard, but several things could still damage it.
Tree Roots: The most common source of sewer line damage. As the trees in your yard grow, their root systems push further into the ground. Roots can grow with enough force to punch through pipe walls, causing a rupture and blocking the flow.
Sediment Buildup: Over time, minerals and other debris in your water may collect on pipe walls, including the walls of the sewer mainline. If enough sediment builds on the sewer line’s walls, it may block water flow. If the block is bad enough, pressure may build in the pipe until it ruptures.
Rust: Most sewer lines are made of metal, which means they will rust or corrode over a long enough period of time. Rusted pipes may crack or rupture. This is particularly likely if your home is old or your pipes are made of substandard material.
High Pressure: If your home’s water is over-pressurized, it may put your sewer line under more strain than it can handle. Over pressurized water may also wear down inner pipe walls to clean drains.
Ground Shifting: If the ground around or under the sewer line shifts, the pipe may detach, bend, or break off. Earthquakes may shake up the ground enough to do this, but other natural disasters or nearby major construction may also be responsible.
