What Happens When You Don't Clean Your Sewer Line Drain

A clogged sewer drain line can cause far more than drainage problems. When left unaddressed, a clogged drain can cause a crack in your sewer line that will wreak havoc on your system and lead to all sorts of issues. As a result, it's essential you have your sewer line cleaned regularly. Learn about some of the problems that can come along with a clogged drain that you fail to have addressed. 

Foundation Damage

A crack in a sewer line can cause significant damage to your home's foundation. Foundations are durable and can withstand some level of exposure to moisture, but prolonged exposure can cause the foundation to develop soft spots. Once a soft spot forms, the foundation may settle. A settling foundation affects the structure of your home and its safety. Even if you avoid direct foundation damage, a cracked line could also cause a sinkhole to develop around the foundation wall.


A sewer system is home to all sorts of unpleasant creatures, including rats. While rats often travel through sewer lines, they aren't provided with an opening to get out of the sewer line and enter into a building. However, when there is a crack in your sewer line, the rats have an open door into your home. Even a small crack comes with this risk as rats have the ability to flatten themselves to fit through tiny spaces. 


Mold and moisture go hand-in-hand, and if you fail to clean your drain line regularly and a crack forms, mold and your home will also go hand-in-hand. A crack in the sewer line creates a humid environment behind your walls, under your floorboards, and other dark, mold-prone spaces. Mold is incredibly dangerous to your health and can cause damage to wood surfaces. 

Unusual Odor

A crack in your sewer line can make your time at home less than desirable. Your sewer line is full of waste — waste that doesn't at all have an enjoyable scent. A crack in your line will allow the gases produced by the waste to seep out and fill the inside of your home. No matter of cleaning or air freshener will allow you to escape the scent until you address the crack. 

You can avoid all the problems mentioned above. However, you do need to have your drain cleaned in order to do so. Contact a technician, like those at Johnson Plumbing, to come to your home, look of your system, and determine the best course of action.
