Many homeowners may not give much thought to their sewer lines, often "out of sight, out of mind." But the truth is, the condition of your sewer line can significantly affect the functionality and well-being of your household. An ignored or unnoticed broken sewer line can lead to expensive repairs and health hazards.
Understanding the signs of a broken sewer line can help you prevent further damage and costs. Here are some warning signs that your sewer line might need some professional attention:
Unpleasant Odors
If there's a persistent smell of sewage in your home or yard, it might be an early sign of a broken sewer line. The odorous smell indicates that sewage isn't effectively being removed from your property.
Frequent Drain Clogs
While an occasional clog is expected, frequently clogged drains may point towards a bigger issue. If you’re experiencing repeated blockages, slow draining, or even backups, your sewer line might be damaged.

Unusual Sounds
Unexplained gurgling noises from your toilets, sinks, or showers could mean that there's a blockage in your sewer line, causing the water to flow in unusual ways.
Soggy or Indented Lawn
Sewage leaks from broken sewer lines can lead to extra dampness in your yard, causing soggy areas or indents in your lawn. In some cases, you may also notice unusually green patches of grass due to the additional 'fertilization' from the sewage leak.
Unusual Rodent or Insect Activity
Rats and some insects are attracted to sewage. If you've noticed an increase in these pests, it might be due to a crack in your sewer line.
Mold Problems
The humidity from a sewage leak can increase the dampness in your home, leading to mold growth. If you notice a sudden appearance of mold coupled with a sewer-like smell, it could indicate a sewer line issue.
Spike in Water Bill
If your water bill suddenly increases without a change in usage, it could mean you have a leak. While it might not always be a sewer line issue, it is worth getting it checked by a professional plumber.
