Common Reasons For Kitchen Sink Clogs
Here is what you need to know.
Food Waste Build Up
Food can fall into the sink when you wash plates. Some small bits go down the drain and stick inside the pipe. More food sticks to it and makes a thick lump. Water then moves slow or stops.

Grease and Oil
Grease from meat or oil from pans can make a hard layer inside the pipe. When that happens food bits stay there too. The water cannot pass. It is best to wipe grease with a paper towel and throw it in the bin. You should not pour oil in the sink.
Soap and Detergent Leftovers
Soap can leave white marks inside the pipe. It mixes with hard water and makes a layer. That layer stops water from going out fast. You can use hot water once a week to help clean that.
Foreign Objects
Small things like plastic or a sponge can block the pipe. Be sure nothing falls into the drain when you wash dishes.
Faulty Drain Trap
If the drain trap is old it may not work well. A bad pipe shape can also hold dirt. That makes clogs come back. With the help of an expert you can avoid these issues.
