Why should you not pour hot water into the sink? A lot of people are doing it wrong without knowing it

This habit seems harmless, but it can cause damage to pipes and drainage systems, affecting both the economy and the environment.

Harmful effects of pouring hot water into the sink
Causes aging of drainage pipes
Unlike before, sink drain pipes were often made of metal, but now they have been replaced by plastic pipes that can withstand high temperatures. Therefore, discharging hot water many times will cause the pipe to age to a certain extent, which in the long run will affect the lifespan of the drainage pipe. This leads to damage, causing you to spend more money on repairing and replacing drainage pipes.

The drainage pipe is deformed and easily cracked

The heat resistance of drain pipes also varies depending on the material used to make the drain pipe. If your family is using PVC drainage pipes, be careful because some types cannot withstand temperatures above 60 degrees. Therefore, if you pour vegetable broth or vegetable blanching water at about 90 degrees, it will cause the pipe to be deformed due to heat, even crack or explode.
