5 Common Causes of Blocked Drains

Blocked drains can be a real headache for homeowners, causing inconvenience and potential damage to your property. To prevent these frustrating issues, it is important to understand what causes them and how to properly maintain your drains. In this article, we’ll dive into the top five causes of blocked drains and provide tips and tricks to keep them flowing smoothly.

1. Hair & Soap Scum

One of the most common causes of blocked drains is hair and soap scum build-up. This can easily accumulate in your pipes and create a blockage, causing water to drain slowly or not at all.


How to Prevent Hair and Soap Scum Build-up:


  • Use a drain strainer in your shower or bathtub to catch any loose hairs
  • Clean your pipes regularly with a plumbing snake or drain cleaner

Avoid using harsh chemicals that can contribute to soap scum build-up

2. Grease & Cooking Oil

Another common cause of blocked drains is the build-up of grease and cooking oil. When these substances cool and solidify, they can stick to the sides of your pipes and form a blockage.


How to Prevent Grease and Cooking Oil Build-up:


  • Never pour grease or cooking oil down the drain
  • Let grease cool & dispose of it in the trash
  • Regularly clean your pipes with a plumbing snake or drain cleaner

3. Foreign Objects

Foreign objects, such as toys and sanitary products, can also cause blocked drains, leading to slow-draining water or complete blockages. Children may accidentally flush toys and other objects down the toilet. Sanitary products, such as tampons and wipes, are another common culprit and can lodge in the pipes when flushed.


How to Prevent Foreign Object Build-up:


  • Dispose of these items properly (never flush them down the toilet)
  • Educate children on what should & should not be flushed
  • Use a drain strainer in your sinks to catch any loose debris
  • Regularly inspect your pipes for any foreign objects
  • Avoid flushing non-biodegradable products, such as wipes & sanitary products, down the toilet

4. Tree Roots

Tree roots can also be a cause of blocked drains, as they can penetrate the pipes in search of water and nutrients.


How to Prevent Tree Root Intrusion:

  • Have your pipes inspected regularly if you have trees near your home
  • Remove roots with a plumbing snake or hydro jetting if they have already infiltrated your pipes
  • Consider installing root barriers around your pipes

5. Debris, Dirt & Dead Leaves

Debris, dirt, and dead leaves can accumulate in your pipes, leading to slow-draining water or complete blockages. This can lead to unpleasant odours and even water damage if the blockage is severe enough.


How to Prevent Debris, Dirt, and Dead Leaves Build-up:


  • Regularly clean your gutters & downspouts to prevent leaves from entering your pipes
  • Use a drain strainer in your sinks to catch any loose debris
  • Consider installing a grate over your storm drain to prevent larger debris from entering
