Kitchen drains take a lot of abuse. Cooking oil, food scraps and soap residue all go down the sink. So kitchen pipes can block faster than you expect.
The good news is that a few habits make a big difference. They cost almost nothing, and they take seconds each day. This guide covers the daily, weekly and monthly steps.
Why kitchen drains block
The main culprit is fat, oil and grease, often called FOG. Hot fat flows easily down the drain. As it cools, it sets and sticks to the pipe wall. Over time it traps food and builds a solid plug.
Daily habits that help
Keep grease out of the sink
Let cooking fat cool and set, then scrape it into the bin. This single habit matters most, since fat causes so many blockages.
- Pour small amounts of oil into a jar and bin it with household waste
- Wipe greasy pans with kitchen paper before washing
- Check what your council accepts for large amounts of used oil
Use a sink strainer
A mesh strainer catches food before it reaches the pipe. Empty it into the food bin after each use. It costs little, yet it stops many blockages.
Scrape plates first
Scrape plates and pans before washing. This matters even with a waste disposal unit. Large amounts of food can still overload the pipe.
Rinse with hot water
After washing greasy items, run hot water for 15 to 30 seconds. This helps push loose residue along the pipe, since warm water keeps fat moving.
Weekly and monthly care
Once a week, pour a kettle of just-boiled water slowly down the drain. The heat can soften grease that has started to build. It is a cheap habit, and it only takes a minute. Do it after a greasy meal for the best effect, when fresh fat softens fastest.
This gentle method gives a deeper clean each month, and it needs only two kitchen items. Follow these steps while the sink stays clear.
- Pour half a cup of baking soda down the drain
- Add half a cup of white vinegar
- Wait 15 minutes while it fizzes
- Flush with hot water
This method is kind to pipes. It can help with light build-up, but it will not clear a full blockage. If water still pools, stop and ask for help instead of trying harsher products.
What to avoid
- Chemical drain cleaners: they may clear a light blockage, yet regular use can harm old pipes
- Coffee grounds: they do not clean drains and can add to a blockage
- Flour and starchy food: these form a paste in the pipe
- Eggshells: small pieces can catch other debris
When to ask a drainage engineer
If the sink still drains slowly after these steps, the problem may sit deeper in the pipe. Repeat blockages can mean damage or a build-up further along. A CCTV drain survey can show the cause.
Drain jetting cleans grease from the pipe wall, which rods may not do. For a stuck sink, see the blocked sink page. Ask the engineer for a written quote before work starts, since prices differ.
