Understanding the Differences Between Your Main Sewer Line and Drain Line

Your sewer line is one of the most important plumbing components in your house; it’s where all the other plumbing lines connect.

When it experiences issues, you could be looking at serious flooding throughout the house. Having established its importance, it’s important that you understand the difference between the sewer line and drain lines.

Let’s get started:

Main Sewer line

This is the line that connects your home to the municipal connection. If your home has a septic system, then this line will connect your home to the septic tank. This line is located underground and is sloped slightly downward.

It is commonly assumed that the sewer line is mainly used to carry away human waste. But in reality, human waste isn’t the only thing that moves through the sewer line. This is why some local plumbers prefer calling it the main line—for the purposes of clarity.

There are a couple of things you must know when it comes to your main line:

  1. You must know where the main line cleanout is located. This will help you assist the plumber carry out sewer line inspections.
  2. You should get cleanouts done routinely.
  3. Always watch out for backups and overflowing drains throughout the house to see if there’s something wrong with the main line. This is because even the most minor clogs can bring wastewater back inside your home, leading to potential health hazards.

Drain line

These lines are located within your home. They neither lead inside your home or outside it. They don’t even lead into the septic tank. They are, however, connected to the main sewer line.

If something goes wrong with the main line, the effects are usually felt across all the drain lines. This is not the case when drain lines experience issues. If one drain line gets affected, you can easily go ahead and use the rest as usual. Issues with drain lines connected to the sinks, toilets, and shower drains are very common in households.

Unlike sewer lines, these ones aren’t located underground. In fact, most drain lines are completely concealed by the finished walls. Some of these are also behind the ceiling or under the floor.
