Sewer Line Check: When, Why, and What We Look For

(A Plumber’s Perspective on Catching Big Problems Early)

Let me say it straight:
Most homeowners wait way too long to check their sewer line.

They wait until there’s a backup.
Until the toilet burps water into the tub.
Until the lawn smells like something died underground.

But the truth is — a simple check now can save you thousands later.

Here’s when I recommend checking your line, why it matters, and what we actually do during the inspection.

When Should You Check Your Sewer Line?

It’s not just for older homes (though that’s a big one).
Here are the real moments to consider it:

  • Before buying a house — always, always inspect underground lines
  • If your home is 20+ years old and the pipes have never been inspected
  • If you’ve had repeat clogs or slow drains
  • After big landscaping or construction projects (ground shifting is real)
  • If you notice weird smells or gurgling from toilets or tubs
  • If roots have been an issue before — they don’t stop growing

Basically, if you’re not sure when it was last checked — it’s probably time.

What We Actually Look For

A sewer line check isn’t guesswork.
We use a high-resolution sewer camera to inspect the full line from your house to the city connection.

Here’s what we’re checking:

  • Blockages — buildup from grease, wipes, debris
  • Root intrusion — tree roots cracking through joints
  • Pipe damage — cracks, collapses, corrosion
  • Offsets — misaligned pipes from settling soil
  • Low spots (bellies) — sections where waste and water pool
  • Signs of past patchwork or DIY “fixes”

We can even mark the location and depth of any problem areas — which makes future repairs much easier (and cheaper).

Common Things I Find

“It was just a slow drain…”
— turns out, a massive root ball wrapped around a cracked clay joint.

“Everything seemed fine!”
— until the pipe turned out to be 80% blocked by years of grease buildup.

“It passed the regular inspection…”
— but the camera showed a 5-foot belly under the foundation slab.

That’s why I never assume. I check.

Is It Expensive?

Nope.

A standard sewer line check costs way less than fixing even a small section of damaged pipe.
And once we inspect it, you’ll know exactly what shape it’s in — with footage to prove it.

It’s like a colonoscopy for your house. Not fun, but smart.
