Steps a Plumber Takes to Line Sewer Pipes
Depending on the plumber's trenchless lining method, they will require one or two access points.
Traditional sewer repair is a process that takes time and effort. In the past, plumbers would typically repair sewer pipes by digging up the affected section of piping and replacing it. The process was the same for replacing any other plumbing part, with the added complication of requiring a foot or deeper trench for access.
Many plumbers now use trenchless lining methods to repair sewer pipes without digging. If hiring a trenchless repair plumber is a consideration to line a home's pipes, these are the steps they will need to take before beginning the repair.
Access and inspection
Depending on the plumber's trenchless lining method, they will require one or two access points. When they have established at least one access point, the plumber will use their diagnostic equipment to assess the sewer line condition. In most cases, this means using a fiber-optic camera to inspect any damaged or leaking areas.
This initial inspection aims to locate the damage and determine the best pipe-lining method. The best option for repairing individual cracks or intrusions will differ from repairing an old, highly corroded pipe. By inspecting the drain, the plumber can determine if the sewer lines are a good candidate for sectional repair or need more comprehensive methods.
Drain cleaning
Most trenchless repair methods require clean drain lines before the process can begin. Since these repair techniques use the existing pipe as an outer layer, any blocks in the drain will prevent proper installation. Lining installers will typically use hydro jetting or similar technology to blast out any debris in the sewer line and create the cleanest surface possible for installation.
Digging and installation
Although sewer lining methods do not require trenches, they sometimes require digging. All lining methods require access points with a minimum diameter for inserting material into the existing pipe. A plumber will require two separate access points for some techniques, such as pull-in-place liners or pipe bursting.
If a sewer line's clean-out needs significant access, digging may be necessary to provide a proper opening. Fortunately, digging two access holes is significantly less involved than digging an entire trench and replacing large pipe portions. In most cases, plumbers can complete the entire procedure in a day or two, even if they must dig their access points.
