You may have heard of the term “clogged mainline” but do you know what it actually is?

What is a Mainline?

A mainline carries wastewater from toilets, showers, kitchen drains and other fixtures to the municipal sewer line or to a septic system. Every building that has drains has a mainline. It is an integral part of a building’s plumbing system.

Signs of a Problem

As with everything else that is used often, problems can occur. Since your mainline is deep underground, it can be hard to notice damage or a blockage immediately. When you notice a problem, have it repaired as soon as possible or you risk flooding and damage to your property. Signs that you have a clogged mainline:

  • Multiple backed-up drains 
  • Unpleasant odors in your building and yard
  • Buildup in the clean-out 
  • Sewage in floor drains 
  • Water backed up in the shower (especially after flushing the toilet)

Common Causes

Mainlines can sustain damage due to environmental factors. These are some of the common causes:

  • Tree Root Invasion: This is often the main culprit when it comes to mainline problems. Tree roots in your yard are naturally attracted to mainlines because of the water and “nutrients” that can come from small leaks. The roots then enter your pipes and grow inside, eventually causing clogs or resulting in a burst mainline pipe. 
  • Corrosion: Aged pipes can cause leaks in your main mainline, which will require replacement. The pipes we will replace them with are more resistant to corrosion, saving you the hassle of having to replace them again anytime soon. 
  • Soil shifting: This causes misalignment of your mainline.
