A seemingly harmless action but causes 2 major dan.gers | March 22, 2025

Pouring hot water into the sink is a common habit in many families, especially when pouring excess water from boiling vegetables or boiling water. This seems convenient but is actually very harmful. We advise you to consider and change this habit to maintain a clean and safe kitchen environment.

Harmful effects of pouring hot water into the sink

Most sinks are equipped with a sewer system to filter wastewater. During cooking, if we pour hot water into the sink, it means we are pouring hot water into the sewer. In the long run, it will cause many serious effects.

1. Reduce the life of the pipe:

The pipes in the kitchen are mostly made of plastic. Although some types have a certain heat resistance, however, when you continuously pour hot water into the sewer, it will reduce the durability and life of the pipe.

Normally, sewer pipes can be used for 30 to 50 years, and if you pour hot water frequently, its lifespan will be shortened, forcing you to replace it sooner than expected.

2. Deformation and cracking of pipes:

Some types of pipes, especially PVC pipes, cannot withstand high temperatures above 60 degrees Celsius. Hot water, especially boiling water from cooking, can reach 90 degrees Celsius, and when poured directly into the sewer, it will cause the pipe to deform or even crack. This can cause serious problems such as leaks or damage, and can even damage kitchen items such as kitchen cabinets or furniture.
