🧼 Here’s the Reason to Always Place an Upside-Down Glass and a Piece of Paper in the Sink Before You Leave for Vacation

🚫 The Problem: Evaporating Drain Traps = Smelly Surprise

Every  sink has a U-shaped pipe underneath called the P-trap.

It holds  water that acts as a seal against sewer gases—blocking foul odors, methane, and even pests from rising up through your pipes.

But when you leave your house empty for days or weeks:

No water runs down the drain

The air gets dry (especially with AC or heat running)

The water in the trap evaporates

➡️ Result?

No seal.

No barrier.

Just open access for rotten-egg smells, drain flies, cockroaches, and ants to move in.

Not exactly the welcome-home vibe you wanted.
