Kitchen drains take more abuse than any other drain in the house. Cooking oil, food scraps and soap residue all go down the sink. It is no surprise that they are the drains we see blocked most often in Banbury homes.
Why Kitchen Drains Block So Easily
The main culprit is fat, oil and grease, often called FOG. When hot, these are liquid and flow away easily. However, they cool in the pipe, harden and stick to the wall.
Over time, that layer catches other debris. Eventually it forms a complete blockage. Because of this, the habits below make sense.
Daily Habits to Prevent Blockages
Never Pour Grease Down the Drain
This is the single most important rule, because grease causes most kitchen blockages. Let cooking oil or fat cool and set, then scrape it into the bin. Pour small amounts into a container and bin it with your household waste, and take large amounts of oil to your local recycling centre.
Use a Sink Strainer
A simple mesh strainer catches food before it enters the drain. Empty it into your food waste bin after each use. It costs very little, yet it stops many kitchen blockages.
Scrape Plates Before Washing
Remove food from plates, pots and pans before they go in the sink. Even with a waste disposal unit, a large amount of food can still overwhelm the pipes. Wiping greasy pans with kitchen roll first helps a lot.
Run Hot Water After Use
After washing up, run hot water for fifteen to thirty seconds. This flushes residue through the pipes. It matters most after you wash greasy items, since grease sets as it cools.
Weekly Maintenance Tips
Hot Water Flush
Once a week, boil a full kettle and pour it slowly down the drain. The heat helps dissolve grease that has started to build on the pipe wall. Do not use boiling water on old or cracked plastic pipes, since it can soften the joints.
Natural Cleaning Solution
For a deeper clean, try this method once a month. It is gentle, yet it works well on light build-up.
- Pour half a cup of bicarbonate of soda down the drain.
- Follow with half a cup of white vinegar.
- Wait fifteen minutes while it fizzes.
- Flush with hot water.
This breaks down organic matter because it is gentle, unlike the harsh chemicals that can damage older pipes. If the sink is already blocked, our guide to five fixes for a blocked kitchen sink goes step by step.
What to Avoid
- Chemical drain cleaners. They can clear a minor blockage, but regular use can corrode pipes.
- Coffee grounds. Despite the myth, they do not clean drains and they add to blockages.
- Flour and starchy foods. These form a paste inside the pipe.
- Eggshells. They break into small pieces that catch other debris.
When to Contact a Professional
If water drains slowly despite these tips, or blockages keep returning, there may be a deeper fault. A professional CCTV drain survey can find the root cause. For persistent blockages, however, drain jetting cleans the pipe walls far better than DIY methods.
A sink that will not clear needs a closer look, because the cause may be deeper. See our blocked sink service. Our tell-tale signs of a drain blockage guide shows when to call. Outside the house, the same grease can block a gully, as covered in how to unblock an outside drain.
