7 Signs Your Sewer Line Is Failing (And What to Do About It in Maryland)

If your home in Montgomery or Prince George’s County has started smelling a little off or your drains are moving slower than usual—don’t ignore it. These could be signs your sewer line is failing, and catching the problem early can save you thousands in repair costs and property damage.

At A-1 Trenchless Water & Sewer Repair Services LLC, we help Maryland homeowners avoid disaster with fast, trenchless sewer line solutions that don’t destroy your yard.

Below are 7 signs you might need sewer repair—and what you should do next.

1. Frequent Drain Backups

If your tub, sink, or toilet keeps backing up even after snaking or plunging, the problem could be deeper—literally. A clogged or collapsed sewer line can block the flow from your entire home.

🔧 What to do: Stop using water and call a licensed sewer specialist ASAP before raw sewage backs up into your home.

2. Bad Odors in the Yard or Basement

A healthy sewer line should be airtight. If you smell a foul, musty, or sewage-like odor in your basement or outside, it likely means sewage is leaking into the soil or foundation.

3. Lush Green Patches in the Yard

That super-green patch of grass might look healthy, but it could mean your yard is being fertilized by leaking sewage. Left untreated, it can become a health hazard and invite pests.

4. Slow Draining Fixtures

One slow drain is normal. But if multiple drains in your home are slow—especially on the lower level—it’s often a red flag for a failing main sewer line.

5. Soggy Spots or Sinkholes

Soft or soggy patches in your yard, especially when it hasn’t rained, could indicate an underground leak. In severe cases, it can even lead to sinkholes or foundation cracks.

6. Gurgling Sounds in Pipes

When your toilet gurgles or your shower drain makes bubbling noises, that’s air getting trapped in your sewer line. It’s often a sign of a partial blockage or improper venting.

7. Unexplained Spike in Water Bills

Leaks in your main water or sewer line can cause your monthly bill to rise sharply—without any increase in usage. Always investigate a sudden bill jump.
