Top Warning Signs You Need Sewer Line Repair (And Why You Should Call a Pro)

When you think of plumbing problems, things like dripping faucets or clogged toilets might come to mind first. But there’s one issue that lurks underground—quietly causing big trouble—and that’s your sewer line. At Dino Plumbing & Service Pros, we’ve seen it all here in Washington, UT, from tree roots breaking into old clay pipes to sewer backups flooding basements. Knowing the warning signs early can save you a major headache (and a hefty repair bill). Let’s walk you through what to look for.

Unpleasant Odors: Smells That Signal Trouble

Smelling something nasty near your drains or out in the yard? That “rotten egg” or sewage smell is more than just unpleasant—it could be a sign of a sewer gas leak. Sewer gas contains hydrogen sulfide, which isn’t just stinky, it’s harmful with long-term exposure. If the smell won’t go away, don’t try covering it with air freshener. It's time to get your sewer line checked out by a pro.

Slow Drains and Gurgling Sounds: The Noisy Warning Signs

A slow drain here and there might just be a little buildup, but when multiple drains are sluggish—or worse, making gurgling noises—that usually means something’s going on deep in your sewer line. Gurgling happens when air is trapped behind a blockage and tries to escape. It’s like your pipes are talking to you... and what they’re saying isn’t good.

Sewage Backups: When It’s More Than Just a Clog

Sewer backups are nasty. If you see water backing up into your sink, tub, or toilet—especially with a foul smell—it’s not just gross, it’s an emergency. This often points to a major blockage or even a collapsed pipe. Trust us, this isn’t the time to reach for a plunger. Give us a call immediately before damage spreads.

Puddles or Lush Spots in the Yard: Hidden Leaks Underground

If you notice parts of your yard are suddenly greener or feel soft and soggy underfoot (and it hasn’t rained recently), your sewer line might be leaking and “fertilizing” your lawn. Sounds nice in theory—until that sewage starts seeping into your soil or basement.

Foundation Cracks and Sinkholes: Structural Damage from Sewer Failures

Water from a damaged sewer line can erode the soil beneath your home, leading to cracks in the foundation, uneven floors, or even sinkholes in serious cases. Don’t ignore small cracks, especially if they’re near plumbing access points.

Toilet Oddities: Bubbling, Fluctuating Levels, and Strange Reactions

If your toilet bubbles when you use the sink or shower—or if the water level in the bowl keeps changing—that’s a sign your sewer system is having trouble venting properly. These pressure imbalances usually point to a clog or break in the main line.

Mold, Mildew, and Moisture: Health Risks from Sewer Leaks

Leaking sewer pipes behind your walls or under your floors create damp, musty spaces that mold loves. Mold isn’t just a nuisance; it can trigger allergies, asthma, and respiratory problems. If you’ve got that musty smell that won’t go away—get it inspected right away.

Unwanted Pests: Rodents and Sewer Flies as Red Flags

Here are a few signs that pests might be piggybacking on your sewer issues:

• Rodents showing up unexpectedly

• Tiny sewer flies near your drains

• Holes or burrows near your home’s foundation

• Mysterious scratching or odors coming from walls

• Increased pest sightings despite recent pest control

If this sounds familiar, your sewer line might be compromised and giving pests a free pass into your home.

Rising Water Bills: The Cost of an Invisible Leak

Has your water bill gone up but you haven’t changed your usage? It might not be your imagination. Undetected sewer line leaks can waste water underground without leaving visible signs—until it’s too late.

Age of the Sewer System: When Time Becomes the Enemy

If your home was built before the 1980s here in Washington or nearby Southern Utah communities, chances are your sewer line may be made of older materials like clay or cast iron. These pipes don’t last forever. If your home is older, a camera inspection can help you stay ahead of costly surprises.
