Sink traps can do more than what you think
That curved pipe underneath your sink is not created just to catch objects that you accidentally drop there, such as earrings or rings, but for other purposes as well.
“Its primary purpose is to store a small amount of water to seal and prevent the flow of noxious sewer gases from coming back into your home,” says The Real Estate Solutions Guy, Robert Taylor.
So next time when you have to fix something under the sink you will remember this fact. Do you notice that small things have actually great meanings and purposes and we do not even know?
