How to tell if your main sewer drain is clogged.

Clogged Main Line Sewer Drain

A sewer line clog can lead to raw sewage backing up out of your drains.  This can not only be hazardous, but can be very costly as well. Know the telltale signs and what to do when your sewer drain becomes clogged.

How can we help?
If you are experiencing a backup due to a clogged sewer line at your home, it is important to stop using any water as it could accumulate in the basement. If you are noticing signs that your main drain line may be clogged, you can schedule a main drain sewer line inspection. Our expert technicians are trained to inspect the line as well as camera the line to see what is causing the problem.

Listen to your home

  • Gurgling noises in your drains or toilet
  • Sewer odor
  • Water backup or flooding
  • Sewage backup

The telltale sign of a sewer line clog is when you see water backing up out of a basement floor drain.  Another sign includes a toilet bubbling when flushed or your hear gurgling noises. 

How do I know if it is a main sewer line clog or a secondary line clog?

If the clog is in the main line, any water that you run through your house will not exit the property, but will surface at the lowest point in your drainage system.  (typically a basement floor drain or shower) If it is a clog in a secondary line (kitchen and bathroom sinks) the backup will be isolated to that specific area.  For example, if you have a clog in a bathroom sink, the water will remain in the basin or may back up into the bathtub.  Sometimes a main sewer line clog will give you no warning until you see it backing up into your home.  If you have a main sewer line clog, discontinue any water usage immediately and contact a plumber. 

Tree roots - the main culprit

Many of the clogged main line drains we see, especially in older homes, are a result of tree roots.  The clogs in newer homes are usually caused by feminine hygiene products, paper towels, and certain brands of thicker toilet paper. As you can see below,  tree roots can penetrate the drainage lines and, over time, clog the line. Our expert technicians will use the appropriate blades to break up the roots and get the drain unclogged.  If the problem is bigger than tree roots, we will work with you to find the problem and take care of the issue.  If you need your sewer line replaced, A.B. May has a team that is dedicated to specifically to just that.  Read more...
