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.
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.
Not all grease is created equal—certain types are more likely to cause issues in your plumbing system:
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.
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.
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.
If grease has been accumulating in your pipes, you may start to notice several warning signs indicating a blockage:
Preventing grease from clogging your drains is easier than you might think. Here are some practical steps to keep your pipes clear:
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.
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.
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.
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.
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.
Grease and oils are major contributors to drain blockages, but with proper disposal habits and routine maintenance, you can minimize the risk of clogs in your kitchen plumbing. Always avoid pouring grease and oils down the sink, and if you suspect a blockage, don’t hesitate to contact Clear Call Plumbers.
