Telltale Signs Your Sewer Lines Are Damaged

Telltale Signs Your Sewer Lines Are Damaged

Your sewers and drains take a lot of abuse. While they probably aren’t filled with mutated turtles fighting ninja battles, just think of everything they are filled with on a day to day basis!

Given all they put up with—human waste, stormwater runoff, tree root invasions—they could easily be damaged and you not realize. And the longer sewer damage goes untreated, the worse it will become. Be on the lookout for these telltale signs that your sewers have been damaged and need repair from the plumbers at Allstar Home Services.

Sewer Backups

Typically caused by a blockage in your sewer line, sewer backups usually show up in the drain closest to the blockage. For example, if you experience backups in every drain on your lower floor, your main sewer line may be damaged; however, if just one drain is backing up, there may be a problem with a single line off the main line.

Smelling Sewer Gas

If you can smell sewer gas in your home—a smell like rotten eggs—you almost certainly have a cracked or broken sewer line. Sewer pipes are airtight, so the only time you would ever be able to smell sewage in your home is when your sewer is damaged.

If you suddenly start seeing mold on your ceilings or walls, call Allstar to check for broken sewer lines, especially if the mold growth is accompanied by sewer odor. Mold can be extremely dangerous to your health, so be sure to find the source of the mold growth quickly!


There may not be samurai turtles in your sewers, but there are rats and bugs, so if you suddenly find unwelcome vermin in your home, there’s probably a break in your sewer line. If you develop a problem with roaches, sewer flies, or rodents, don’t just call a pest control company; also call Allstar to inspect your pipes for damage.

Outdoor Signs of Sewer Damage

Uneven Grass Growth

Sometimes the signs of sewer damage aren’t in your home but in your yard. One such sign is a patch of grass that is more green and lush than the rest. Sewage is essentially concentrated fertilizer, so this super lush patch of grass could be a sign that you have an underground sewage leak.

Another sign you have an underground sewage leak is the formation of dips in your landscape. Sustained sewer leakage will lead to soil dissipation, which will manifest as a large divot or indentation above the damaged sewer line, or in more extreme cases, a sinkhole.

Waste Pooling

This is one of the most obvious signs of sewer damage, as a pool of wastewater won’t appear in your yard without a sewage line having broken underground. Thankfully, locating the sewer leak is easy in these instances, as the breakage is almost always directly below the waste pool.
