The Real Deal on Covering Your Sink Before Vacation

Why Do People Think They Need This Hack? The Real Plumbing Issue Behind This Idea
As mentioned above, every sink, tub and floor drain in your home contains a small piece of plumbing magic referred to as a P-trap. Most people have heard of the P-trap, but may not know that the curve of the P-trap wasn’t designed to catch lost jewelry or hairballs, but rather to hold water on purpose. The water within the P-trap creates a physical barrier between your home and the large sewer system outside. This barrier is commonly known as the “water seal” and provides a level of protection by blocking unpleasant sewer gases and odors from entering your home.Plumbing Fixtures & Equipment
