🤔Here is Why You Should Always Leave an Upturned Glass and a Piece of Paper in the Sink Before Going on Vacation👀👇

A viral tip suggests placing a piece of paper and an upside-down glass over a sink drain to block odors and insects. While creative, this method doesn’t fully address how household plumbing actually works.Every sink, tub, and floor drain is designed with a curved section of pipe that holds water. This water creates a seal that blocks sewer gases and pests from entering your home. When a drain isn’t used for a long time, that water can slowly evaporate, breaking the seal. Short trips usually aren’t an issue, but longer absences—especially in hot or dry conditions—can allow evaporation to occur.
