The main sewer line is the most important and biggest piece of plumbing in your whole house. All of the pipes, drains, and plumbing fixtures are connected to it.  

Nowadays, most homeowners have run into the unlucky case of having a slow-running bathtub or sink or a clogged drain. Though a minor clog can be an agony, usually, it is a simple fix.  

But, if every single drain in the house starts backing up at once, what will happen? 

The answer to that question is probably sewer drain clog. Oftentimes, when drain cleaning tasks do not work, the replacement or repair of a whole sewer line is needed. That’s why you have to look for a professional plumber with a lot of excellent Hamilton Plumbing Company Reviews. 


When it comes to clogging lines, oil, fats, and grease are a few of the biggest culprits. It isn’t an excellent idea to pour oil, grease, and other fats down your drain. 

Hot grease should always be poured into a coffee jar or can. You could throw it away once it solidifies. A lot of homeowners assume that it will help wash the grease away when they run hot water when pouring down grease. However, that isn’t the case.  

Flushing Debris down the Toilet 

It is crucial to know what you can’t and can flush down your toilet for the sake of the health of your plumbing system.  

It will cause sewer drain problems if you treat your toilet like a trashcan. When flushing the toilet, you have to ensure only toilet paper and human waste goes down. That’s the number one rule to keep in mind.  

Tree Root Infiltration 

Oftentimes, old sewer lines were built out of clay or other materials that are porous. Furthermore, unlike the PVC pipes nowadays, the connections between pipe sections before were not really tight.  

Roots search for water sources as the shrub and tree grow. In order to reach the water inside, they will grow into the pipe if they latch onto the sewer pipe. It can cause the line to break as the roots grow over time.  

Sagging Sewer Lines 

Though this is out of the control of a homeowner, sagging sewer lines occur over time. Whenever a part of the pipe has sunk because of the soil or ground conditions, it will result in a “bellied” pipe.  

The low area in the line would start to gather waste and paper. This will result in repeat blockages.  

Serious Pipe Damage 

The sewage will not be able to drain over the system properly when sewer pipes are ruptured or broken. This will lead to frequent and immediate backups. Here are several causes of sewer pipe damage.  

  • Leaking joints where the seals between the pipe’s sections have broken. This enables sewage and water to escape.  
  • Corrosion of an old pipe. This will result in pipe collapsing or breaking.  
  • Sewer pipe ruptures because of increased traffic on the above ground, settling, shifting soil, or the use of heavy construction machinery above ground.
