Sewer line replacement for older Salem laterals

Many older Salem homes still drain through the pipe they were built with: short clay sections, poured concrete, or postwar Orangeburg. Each of those materials ages out in its own way. Clay joints open up and admit roots, concrete erodes from the inside, and Orangeburg slowly flattens until waste cannot pass. Once the damage runs the full length, a new line is the lasting fix.

A replacement is a bigger project than a rooter call, and you should see why it is needed. We start from the camera video, show you the defects along the run, and walk the path the new line will take. You get a price before work starts and a clear plan for the trench, the yard and the hours your plumbing will be offline.

Why clay, concrete and Orangeburg laterals wear out

Clay pipe is strong, but it came in short sections with mortar or early rubber joints, and every joint is a weak point for roots and settling. Concrete laterals soften and pit as sewer gases attack the inner wall. Orangeburg, made from tar-soaked fiber, was a cheap postwar material that deforms under the weight of the soil. In each case the pipe walls are tired long before anyone notices trouble inside the house.

Digging the trench and laying new pipe

After utility locates, we open a trench along the route, usually following the old line to the connection point. The old pipe comes out where we can reach it or stays in place where it is abandoned. New PVC is laid on a compacted bed with a steady fall toward the main, with a quarter inch per foot as the usual target on a house lateral.

• Utility locates finished before the first shovel
• Bedding gravel placed under and around the new pipe
• Every glued joint checked before backfill
• A cleanout set near the foundation for future access
• Backfill compacted in layers to limit settling

Tying in at the public main and passing inspection

At the street end, the new pipe joins the existing connection or a new tap, depending on what we find when we expose it. We confirm where your private line ends before planning the work. In Oregon, a sewer line replacement generally needs a plumbing permit, so we pull it and schedule the inspection while the trench is still open and the inspector can see the new pipe.

What replacement day looks like at your house

Most replacements take one to three days, depending on length, depth and what sits above the line. Toilets and drains are offline while the old pipe is disconnected, so we plan that window with you and keep it as short as the work allows.

The trench is backfilled in compacted lifts and the topsoil put back on top. Lawn usually needs reseeding once the soil settles through a wet season, so we leave the fill mounded slightly and it sinks close to level by spring.
