Before leaving home for several days, most people remember to lock the doors, unplug unnecessary appliances, and take out the trash. But there is another small area worth checking: your kitchen sink and drain.
A viral household tip suggests placing a piece of paper over the drain and turning a glass upside down on top of it. But why would someone do that? 🤔

Why Cover the Sink Drain?
When a home is empty for several days, people may want to prevent small insects or unpleasant odors from becoming a problem.
A simple cover over the drain can act as an extra physical barrier, helping prevent insects from emerging through an open drain opening.
The upside-down glass also helps keep the paper in place.
Does This Replace Proper Drain Maintenance?
No. The best protection against drain odors and plumbing problems is still proper maintenance.
Before leaving for vacation, consider:
- Running water briefly in infrequently used sinks.
- Checking for leaks under the sink.
- Removing food debris from the drain.
- Emptying the garbage and cleaning the sink.
- Making sure the drain trap contains water, as the water barrier helps block sewer gases.
Why Use an Upside-Down Glass?
The glass serves a very simple purpose: it weighs down and protects the paper.
The paper covers the drain opening, while the glass helps prevent it from moving.
It is an easy temporary trick, particularly if you simply want an additional cover while your home is empty.
Other Smart Things to Do Before Vacation
Before leaving home for an extended trip, you may also want to:
🗑️ Take Out the Trash
Food waste can create unpleasant odors and attract insects.
🚰 Check for Leaks
Inspect faucets and pipes for dripping or signs of water damage.
🥫 Don’t Leave Food Out
Store food properly and clear away crumbs.
🔌 Unplug Unnecessary Devices
Where appropriate and safe, unplug devices you don’t need running while away.
🏠 Ask Someone to Check Your Home
For longer trips, a trusted person can occasionally check for leaks or other unexpected problems.
The Bottom Line
Placing paper over a sink drain and covering it with an upside-down glass is a simple temporary barrier, but it is not a magical solution to plumbing problems.
A clean sink, a functioning drain trap, and checking your home for leaks are much more important before going on vacation.
Sometimes the simplest household tricks are useful—but knowing why they work makes them even better! 😊
