How do I know if it's a sewer leak and not just a clog?

A clog usually clears with snaking and doesn't come back for a while. A leaking or cracked line often causes recurring backups, a persistent smell, or a wet spot in the yard that doesn't dry.

What causes sewer line leaks in Stillwater specifically?

Root intrusion from mature trees and joint separation from clay soil movement are the two most common causes we find in older neighborhoods.

Should I use a chemical drain cleaner if I suspect a sewer leak?

No. It rarely resolves a structural issue like a crack or root intrusion, and can make a later camera inspection harder to interpret.

Will I need to dig up my yard to fix a sewer line leak?

Not necessarily for the inspection. Digging is targeted to the exact marked location if a repair is needed, rather than along the whole line.

What to Do If You Suspect a Sewer Line Leak

A sewer line leak and a simple clog can look similar at first, but they need very different responses. Knowing which one you're dealing with saves time and, in some cases, prevents a small problem from becoming a much bigger one.

Signs It's a Leak, Not Just a Clog

Recurring backups after snaking: A clog that keeps coming back despite being cleared often means a cracked or root-intruded line, not a simple blockage.
A persistent smell near the cleanout or yard: Sewer gas escaping through a crack has a distinct, unpleasant odor that doesn't go away.
A soft, damp patch in the yard: Especially one that stays wet even during dry stretches.
Multiple drains backing up at once: A sign the problem is in the main line rather than one fixture's branch line.

What Causes This in Stillwater

Two things show up more here than elsewhere: root intrusion from mature trees near older sewer lines, especially in neighborhoods close to campus, and joint separation from Stillwater's clay soil, which swells and shrinks enough over time to shift a buried pipe's joints. Older neighborhoods with clay or cast iron sewer pipe are more vulnerable to both.

What to Do Right Now

Stop running water into the affected drains if you can, extra water just makes a backup worse. Avoid using a chemical drain cleaner on a suspected sewer line issue, it rarely fixes a structural problem and can complicate a later camera inspection. If the smell or backup is severe, treat it as something to address quickly rather than wait out.

How It Gets Diagnosed

A camera run through the line shows its actual condition: cracks, root intrusion, or a bellied section where the pipe has sagged. If the camera doesn't clearly confirm the source, smoke testing pushes non-toxic smoke through the line and shows exactly where it escapes, useful for cracks that aren't visible at the camera's angle.

What Happens After Diagnosis

Depending on what's found, repair options range from a targeted spot repair at a single joint to a longer section replacement if damage is widespread. A locator paired with the camera marks the exact depth and position on the surface, so any digging that's needed is targeted instead of exploratory.
