7 Tell-Tale Signs of a Cracked Pipe

August 4, 2025by Alex

Your sewer system is a vital component of your home’s plumbing infrastructure. It carries away wastewater from your home and into the city’s main sewer line. However, just like any other part of your home, sewer pipes can develop issues over time. One of the most common problems with sewer pipes is cracks. Cracks can occur due to age, corrosion, and environmental factors. Here are the 7 tell-tale signs that your sewer pipe might be cracked:

1. Slow Drains

If you notice that your drains are slow to empty, it could be a sign that your sewer pipe is cracked. A crack in your sewer pipe can cause blockages that prevent water from flowing freely through the pipes.

2. Foul Odors

If you detect a foul odor coming from your drains, it could be a sign of a cracked sewer pipe. Cracks in the pipe can cause wastewater to leak out, leading to a strong smell of sewage.

3. Mold Growth

If you notice mold growing in your home, it could be a sign of a cracked sewer pipe. The moisture from the leaking wastewater can create the perfect environment for mold growth.

4. Extra Green and Lush Patches of Grass

If you have patches of extra green and lush grass in your yard, it could be a sign of a cracked sewer pipe. The leaking wastewater can act as a fertilizer and cause the grass to grow faster and greener.

5. Wet Spots in the Yard

If you notice wet spots in your yard, it could be a sign of a cracked sewer pipe. The leaking wastewater can saturate the ground and cause the soil to become waterlogged.

6. Foundation Problems

If you notice cracks in your foundation or walls, it could be a sign of a cracked sewer pipe. The leaking wastewater can erode the soil beneath your home’s foundation, leading to settling and cracks.

7. Insect and Rodent Infestations

If you notice an increase in insect and rodent activity in your home, it could be a sign of a cracked sewer pipe. The leaking wastewater can attract pests looking for a source of water.

If you notice any of these signs, it’s important to call a professional plumber immediately to inspect your sewer pipe. They can use advanced tools such as pipe cameras [6] to inspect the pipes and locate the source of the problem. Depending on the extent of the damage, they may recommend pipe relining [2] as a solution. This no-dig method uses an epoxy liner to repair the damaged pipe and restore proper function.

It’s important to address a cracked sewer pipe as soon as possible. Ignoring the problem can lead to more significant damage and costly repairs down the line. Regular maintenance and inspections by a professional plumber can help prevent sewer pipe issues from developing in the first place. And if you do notice any of the signs listed above, don’t hesitate to call for help.
