Your sewer line is buried underground, out of sight and out of mind — until something goes wrong. A failing sewer line doesn’t announce itself with a single obvious event. It sends warning signs that build over weeks and months. Catching these signs early saves you from sewage backups, property damage, and emergency repair bills. The experts at Repipe Solutions Inc. see these red flags every day in Houston homes.
1. Frequent and Multiple Clogged Drains
A single clogged sink is a minor inconvenience. But when your toilets, showers, and sinks all back up at the same time — or in quick succession — the problem isn’t at the fixture level. It’s in your main sewer line. Every drain in your house feeds into that one pipe. When it’s blocked or broken, wastewater has nowhere to go but back into your home.
If you’re calling a plumber for drain cleaning more than once or twice a year, stop treating the symptom. You need someone to look at the main line.
2. Slow Drains Throughout the House
This is the subtler version of frequent clogs. All your drains are sluggish — not completely blocked, but noticeably slow. You might also hear gurgling sounds from your drains or toilet when water flows through the system. That gurgling is air getting trapped in the line because of a blockage or break in the sewer pipe.
3. Sewer Gas Odors
A properly sealed plumbing system is airtight. You should never smell sewer gas inside your home or in your yard. If you notice a persistent rotten-egg smell near your drains, in your bathrooms, or outside near where your sewer line runs, it means there’s a crack or break in the pipe. The EPA warns that raw sewage contains bacteria, viruses, and parasites that pose serious health risks. Don’t ignore the smell.
4. A Soggy, Extra-Green Patch in Your Yard
A broken sewer line leaks water and waste into the surrounding soil continuously. This creates a spot in your yard that’s always damp or swampy, even when it hasn’t rained. You might also notice one area of grass that looks greener and lusher than the rest. That’s because the leaking sewage is acting as fertilizer. In Houston’s clay soil, this moisture can also cause uneven settling around the leak.
5. Foundation Cracks or Settling
This is one of the most alarming warning signs. A sewer line leak under or near your foundation erodes the soil that supports your home. Over time, this loss of support can cause your foundation to sink, shift, or crack. If you notice new cracks in your foundation, walls, or floors — especially if they appear alongside other symptoms on this list — a failing sewer line could be the cause. Houston’s expansive clay soil makes this problem worse, since the moisture from a leak causes the soil to swell and shift unpredictably.
6. Pest Infestations
A sudden unexplained increase in rats, mice, cockroaches, or other pests can point to a broken sewer line. Rodents live in municipal sewer systems and can enter your home through cracks in your pipes. Insects are drawn to the moisture and organic material from a leaking line. If your pest control company can’t find an obvious entry point, a sewer camera inspection may reveal the real source.
7. Mold and Mildew Growth
A sewer line that breaks behind a wall or under your slab creates constant moisture. That moisture breeds mold and mildew, especially on the lower levels of your home. If you see mold on walls or smell a musty, damp odor combined with sewer smells, you may have a hidden pipe leak feeding the problem.

Don’t wait for a full sewage backup to take action. A professional sewer camera inspection is the fastest, most accurate way to find out what’s happening inside your pipe. The camera shows the exact location and type of damage so you can make an informed decision about repair or replacement.
