A sewage leak is more than an inconvenience—it can be a health hazard and a warning sign of major plumbing issues. Catching a leak early can prevent damage, contamination, and thousands in repair costs. But what does a sewage leak look (or smell) like?

Common Warning Signs of a Sewer Leak

Unusual Odors

If you smell rotten eggs or sulfur in or around your property, especially near drains or your yard, this could indicate leaking wastewater.

Slow Draining or Gurgling Pipes

If multiple drains in your home are draining slowly or making strange noises, this could mean a blockage or a leak in the main sewer line.

Unexplained Water Damage

Damp spots on walls, ceilings, or floors with no obvious source can be signs of hidden sewer leaks. Over time, these leaks can increase the risk of mold growth and structural issues.

Soggy or Greener Patches in Yard

Sewage leaking into the soil will make patches of your lawn overly lush, soggy, or sunken—particularly over the sewer line path.

Increased Pest Activity

Rodents and insects are attracted to leaking sewage. A sudden increase in pests could point to a sewer issue underneath or around the property
