Grease and Oils: Major Contributors to Drain Blockages and How to Prevent Them

One of the most common causes of drain blockages in kitchen plumbing systems is the improper disposal of grease and oils. While it might seem convenient to pour hot grease or cooking oil down the sink, these substances can lead to severe clogs as they cool and solidify inside the pipes. At Clear Call Plumbers, we often see the long-term effects of grease build-up, and in this blog post, we’ll explore why grease and oils cause blockages, the signs of a grease-related clog, and how to prevent these issues effectively.

How Grease and Oils Cause Drain Blockages

When you pour grease or cooking oil down the drain, it’s usually in liquid form because it’s still warm. However, as it cools, it solidifies and sticks to the inner walls of your pipes. Over time, this layer of grease builds up, narrowing the passage and reducing water flow.

The sticky nature of grease also causes other debris, like food particles and soap residue, to adhere to it, further contributing to drain blockages. Eventually, the grease and trapped debris create a hardened obstruction that can cause serious plumbing problems, including slow drainage, foul odors, or complete blockages that require professional intervention.

The Most Common Grease-Related Clogs

Not all grease is created equal—certain types are more likely to cause issues in your plumbing system:

  1. Cooking Oils (Vegetable, Canola, Olive) While liquid oils may seem harmless, they can combine with other substances in your pipes and form a sticky residue. Over time, this layer attracts food particles, soap, and other debris, gradually building into a blockage.

  2. Animal Fat and Bacon Grease Fats from meat products, like bacon grease, are especially problematic. These fats solidify quickly when cooled and can create thick, stubborn blockages that are difficult to clear without professional tools.

  3. Butter and Margarine Similar to cooking oils, butter and margarine also solidify as they cool, leading to build-ups that restrict water flow through your pipes.

Signs of a Grease-Related Drain Blockage

If grease has been accumulating in your pipes, you may start to notice several warning signs indicating a blockage:

  • Slow Draining Water: One of the first signs is slow drainage in sinks, particularly in the kitchen. This indicates that grease has built up in the pipes, preventing water from flowing freely.
  • Gurgling Noises: When grease blocks part of the drain, it can cause air pockets that lead to gurgling sounds when you run water.
  • Foul Odors: A blockage caused by grease can trap food particles, which then decompose and create unpleasant smells emanating from the drain.
  • Complete Blockage: If the grease build-up becomes severe, you may experience complete drainage failure, requiring immediate professional attention.

How to Prevent Grease-Related Drain Blockages

Preventing grease from clogging your drains is easier than you might think. Here are some practical steps to keep your pipes clear:

  1. Dispose of Grease Properly Instead of pouring grease down the drain, let it cool and solidify. You can then scrape it into a container and dispose of it in the trash. For cooking oils, use a container to collect them and discard the entire container once it’s full.

  2. Use Drain Strainers Installing a drain strainer in your kitchen sink can catch food particles that might combine with grease and create blockages. Regularly clean the strainer to keep it effective.

  3. Run Hot Water After Washing Dishes If you suspect any oil or grease may have gone down the drain, run hot water immediately afterward. This can help flush the grease through the pipes before it has a chance to solidify.

  4. Use Dish Soap Grease-fighting dish soap can help break down some of the fat before it cools and solidifies. Using soap and hot water together is more effective at keeping your pipes clear.

When to Call a Professional for a Grease-Related Blockage

Even with preventative measures, grease-related clogs can still occur, especially if grease has been building up over time. If you notice any of the signs mentioned above, such as slow drainage or foul odors, it’s important to call a professional plumber. At Clear Call Plumbers, we use advanced techniques like hydro-jetting to clear grease blockages efficiently. This method uses high-pressure water to break down and flush out the grease build-up, restoring proper water flow.
