Main Sewer Line Replacement

Platinum Plumbing provides professional main sewer line replacement for homeowners throughout Longview, Kelso, and nearby communities. Over time, aging pipe, tree roots, soil movement, and corrosion can damage a sewer line. As a result, homeowners may experience backups, slow drains, and poor drainage.

To begin, our team excavated the failed residential sewer line and removed the damaged piping. Next, we installed new ABS sewer pipe at the proper grade and connected it to the existing plumbing system. Once installation was complete, we tested the new line, backfilled the trench, and restored the landscaping.
