How often do you wash dishes and throw food leftovers into the kitchen sink to save time? This habit is absolutely wrong, since you risk to clog the plumbing and to have to call the plumber. Many people believe that, in contact with water, pasta, coffee grounds and cereals are reduced to sludge and end up in the sewers, but actually they just create real blocks. Here are the foods that you should never throw into the kitchen sink.

Pasta, rice and potato peels
Pasta, rice and potato peels are the foods that are more often thrown into the kitchen sink but that unfortunately clog the plumbing. These foods are rich in starch and therefore they tend to swell in contact with water. So it is better to throw these food leftovers in the garbage can.

2. Oil
In spite of what you might think, oil is one of the food products that mainly clogs the plumbing. Even if it is liquid, it solidifies quickly, forming blocks of epic dimensions. It would be better to pour the oil into a jar and then throw it away, while if you throw small quantities into the kitchen sink then you should let hot water flow for the next 2 minutes.

3. Coffee grounds and eggshell fragments
Although coffee grounds seem to be like a powder, they can actually devastate the drainpipes of your kitchen sink, just like the fragments of eggshells. The reason? They remain intact in contact with water, and they are not eliminated. Then, it’s better to throw them in the garbage can.

4. Seeds and cereals
The seeds of fruit and vegetables and cereals are too solid to be disposed of in the kitchen sink. In contact with water, they become softer but they remain intact anyway. To avoid clogging the pipes, it is better to throw them in the garbage can. 5. Filamented foods
Filamented foods such as celery or asparagus should never be thrown into the kitchen sink as they could wrap on themselves, creating blocks in the drainpipes. So before throwing them into the garbage cam, it is therefore necessary to cut them into very thin pieces.
