Before heading out for a vacation, most people focus on packing, locking doors, and turning off appliances. But there’s a simple trick that’s been gaining attention online: placing an upside-down glass with a piece of paper in your sink.
At first, it sounds strange—but there’s actually a practical reason behind it.
The Problem You Might Not Think About
When you leave your home for several days, especially in warm weather, your plumbing system can become inactive.
This can lead to:
- Unpleasant odors coming up from the drain
- Evaporation of water in the pipes (which normally blocks smells)
- Small insects or bugs entering through the drain
Even if your home is clean, returning to a bad smell can be an unpleasant surprise.
How the “Glass and Paper” Trick Works
The idea is simple:
- Place a small piece of paper over the sink drain
- Put an upturned glass over it
This creates a temporary seal over the drain.
What this does:
- Helps block odors from coming up
- Reduces airflow through the drain
- Acts as a barrier for small insects
The paper helps improve the seal, while the glass keeps everything in place.
Why It’s Effective
Your drain is connected to a larger plumbing system, and normally, a water trap (called a P-trap) prevents smells from rising.
But when water sits unused for days, it can evaporate slightly, weakening that barrier.
By covering the drain, you add an extra layer of protection.
Other Helpful Tips Before Leaving
While this trick can help, it’s even more effective when combined with a few simple steps:
- Run water down the drain before leaving to refill the trap
- Avoid leaving food residue in the sink
- Take out the trash
- Clean surfaces to prevent odors
These small habits can make a big difference when you return.
Is It Necessary?
Not everyone needs to do this. In many homes, plumbing systems work well enough that odors won’t be an issue.
However, in older homes or warmer climates, this trick can be a simple and low-effort precaution.
The Bottom Line
Placing a glass and paper over your sink before vacation might seem unusual—but it’s actually a clever way to prevent odors and keep your home fresh while you’re away.
Sometimes, the simplest tricks are the ones that make the biggest difference—
and this one might just save you from an unpleasant welcome home.
