How To Tell If My Underground Sewer Line Is Leaking


Unfortunately, most people don’t catch sewer line leaks until it’s too late. After all, these leaks occur underground so it’s not always obvious there’s a leak in the first place. However, there are a number of signs to look out for that could tip you off:

  • Odd Sounds: Notice a constant sound of running water? This should be a huge red flag. This sound can often be heard in the walls or overhead and if your faucets are off and your toilet is not running, you may have a leak.
  • Wet Floor: Floors feel spongy or moist? Your plumbing network runs through your home and is connected to the main sewer line. As water pools around those connections, it can cause damage to interior flooring.
  • Bad Odors: You may also notice bad odors around your property or an increase in mold and mildew. Leaky lines create the perfect environment for bacterial growth.
  • Cracks: If you notice cracks in your foundation, it may be because the leaks are causing a shift in the ground. As the water starts to pool in the areas around the leak, it drenches the soil and then undermines the structural integrity of your foundation.
  • Growth in Landscape: Yard suddenly growing very well in some areas? The sewage tends to act as fertilizer for the grass and cause it to grow faster than normal.
  • Rodent Problem: Unfortunately, rodents, such as rats and mice, love the smell of sewer lines. This means they will often show up before you can even detect the problem. So if you notice rodents in your backyard, it’s a good sign your pipes are leaking.

  • Higher Utility Bill: Leaks can cause utility bills to spike. Even the smallest drips tend to add up quickly, so if you notice that there are drastic changes, despite using the same amount of water, you probably have a leak.
