Down the drain: 2 common things that should never be poured out into the sink

How often do we rinse off dishes, food containers and other things in the sink before putting them in the dishwasher. This is the habit of many, but can lead to problems.

Solid food residue should obviously be thrown in the garbage, but certain liquids or other viscous substances poured down the drain can, in the long run, create blockages. Two liquids, in particular, are of this nature.

The first liquid to avoid pouring down the drain is actually an entire category: all cooking oils. Whether it's frying oil, seasoning oil or dripping - none of these should be poured down the drain.

These oils are fatty substances which, when in contact with cold water, solidify and cause blockages. A blockage can form right at the opening of the drain. In this case, it is relatively easy to clear the obstruction; but at other times, the obstruction can form much further down the plumbing and requires a plumber's intervention.

So, what can we do with used oil? Well, we should get into the habit of storing used oil in plastic containers and regularly taking it to recycling centers (or disposing of it according to the instructions from your local municipality).

Delicious in a thousand recipes, honey can be harmful to drains. The reason lies in its viscosity: honey, due to its consistency, adheres to the walls of the drains creating an obstruction over time.

However, there is a "positive" side: honey is decidedly more soluble than oil, so by using hot water, you should be able to easily clear a honey-caused blockage. Certainly, it will be much easier to clear than an oil blockage.

Of course, you can avoid this risk entirely by simply throwing empty (or near empty) honey jars in the trash!

In short, the rule is always to try to ensure that only soap and water end up in the drains, and to keep them clean and clear using hot water, bicarbonate of soda or vinegar.
