The main cause of a blocked kitchen sink is remnants of food and build-ups of grease. Residue from soap and other cleaning products can also cause blockages over time, or make blockages even worse.

Usually, your kitchen sink becoming blocked is a long process. Gradually, the build-up of food, grease and cleaning products makes the drain narrower, until it becomes blocked completely.

Although less common, a drain can become blocked due to improper installation and old drainage pipes. Cast iron pipes for example, 

can become blocked due to a buildup of rust, dirt, grime and waste. If you think this is the cause of the blocked kitchen sink, it could be worth having them professionally cleaned or replaced with plastic pipes.

A sink can easily get blocked with daily use. The tips below will help you prevent a blocked kitchen sink.

1. Avoid leaving food in the kitchen

Before you put your dishes in the kitchen sink, make sure you empty all of the leftovers into the bin. You can then rinse the plate clean or place it into the dishwasher. Filters for the plughole are also useful at preventing food from getting down the drain.

2. Pour hot water down the drain regularly

Hot water can remove some grime and build-ups of grease, without damaging your pipes. You should always wash your dishes using hot water, as this is more hygienic as hot water removes more germs than cold water. It also helps prevent build-ups of grease.

3. Use soda regularly to rinse the drain

Soda can also help to remove build-ups of grime.

4. Never throw frying oil or gravy in the sink

Although tempting, you should avoid throwing cooking oil down your kitchen sink. Once this cools, it solidifies. It can then cause a build-up of grease and cause a blockage. Gravy also solidifies once it cools. You should instead throw these in the bin. However, make sure you use high-quality binbags to avoid leaking.
