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have been replaced by plastic pipes that can withstand high temperatures.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.
