Blocked Sewer Lines…How Can You Tell?

Feb 18, 2020

For most homeowners, the most they know about sewer lines is that they drain waste water to the underground main sewer. Since the sewer lines are hidden behind the walls of a home, most homeowners only get to realize a blockage when extensive damage has occurred.

Left unaddressed, blocked sewer lines result in serious health hazards such as raw sewage finding its way out of the drains. Here is what you need to know about blocked sewer lines.

There are multiple sewer lines in your home, which unfortunately, also means multiple fronts from where blockage could occur. In most cases, lifestyle practices are the number one cause of sewer blockage. Habits such as flushing sanitary products like extra thick toilet paper, female hygiene products or even facial towels could block sewer lines. Draining grease in the kitchen sink is another common but overly ignored cause for sewer lines blockage.

Tree roots could also lead to blocked sewer lines. As they seek warmth, moisture and nutrients, the tree roots creep into the loose joints or tiny cracks present in the sewer lines. Blockage occurs once the roots grow into the sewer line or when flushed products are caught by the roots and accumulate behind it.

How to Tell When Sewer Lines are Blocked

Slow draining of water from your sinks or bathtub is usually the first sign of a blocked sewer line. Other signs include bubbles and gurgles when you run water, water backup on multiple drains (sink, bathroom, or roof vent) and water backing up when you flush the toilet or when you drain your washing machine.

While using a plunger could work for minor blockages, it is best to leave the unblocking to professional plumbers.
