After cooking potatoes or pasta, many housewives pour boiling water directly into the sink.
Few people know that such an act can cause certain problems.
Why You Shouldn't Pour Boiling Water Down the Sink
The reason lies in the material from which the sink, pipes and siphon are made.
Thus, for the production of drain pipes, polyvinyl chloride (PVC) is mostly used, which is a fairly cheap and flexible polymer. It can withstand water temperatures up to 60 degrees and is able to withstand short-term (up to 1 minute) exposure to boiling water.
If you pour boiling water into the sink for a long time, PVC can become very deformed due to increased plasticity with increasing temperature. The pipes will not return to their original state. Moreover, when the material cools down and decreases in volume, cracks may appear on the pipes, which naturally leads to a breach of the system's tightness.
A large amount of boiling water flowing through the pipes causes the sealing gaskets that ensure the tightness of the connections to expand and cease to perform their function.
Finally, hot water can also damage the sink material - if you turn on cold water after a large amount of boiling water. As a result, the material, which initially expanded sharply, will decrease in volume, and this is fraught with cracks in the sink.
