Packing for a vacation usually involves checking luggage, locking doors, unplugging electronics, and making sure windows are secure. Yet one small household task is often forgotten: preparing your kitchen and bathroom sinks.
While it may seem like a minor detail, taking a few minutes to care for your drains before leaving can help reduce unpleasant odors and make your return home more enjoyable.
Why Unused Drains Can Develop Odors
When a home sits empty for several days or weeks, the plumbing system isn’t being used regularly.
In most homes, drain traps hold water that acts as a barrier between your living space and the sewer system. If a trap loses enough water through evaporation—particularly during long absences or in hot, dry conditions—unpleasant sewer odors may become noticeable indoors.
In addition, organic residue inside drains can sometimes contribute to musty smells if left undisturbed.
Can Drains Attract Insects?
Some household insects, including drain flies, may breed in organic material that accumulates inside pipes. Other pests can occasionally enter through plumbing systems if suitable openings exist.
While covering a drain isn’t guaranteed to prevent every type of insect, creating a temporary barrier may help reduce the chance of small pests emerging through unused drains during an extended trip.
A Simple Drain-Covering Method
One popular household tip involves placing a clean paper towel over the drain opening and covering it with an upside-down drinking glass.
The idea is simple:
- The paper towel provides a lightweight cover over the drain.
- The inverted glass helps hold it securely in place.
- Together, they create an additional barrier that may help limit airflow from the drain while discouraging small insects from entering the room.
Although this method isn’t a substitute for proper plumbing maintenance, many homeowners use it as an extra precaution before traveling.
Prepare Your Sink Before You Leave
A few simple steps can help keep your sink clean while you’re away.
1. Clean the Sink
Wash away food residue, soap buildup, and standing water from both the sink basin and surrounding surfaces.
2. Freshen the Drain
Pour hot water down the drain to help rinse away light residue. Some homeowners also use white vinegar as part of their regular cleaning routine to help reduce odors.
Avoid mixing vinegar with bleach or other household cleaning chemicals.
3. Dry the Area
After cleaning, wipe the sink dry. Removing excess moisture can help reduce conditions that some insects prefer.
4. Cover the Drain
Place a clean paper towel over the drain and gently set an upside-down glass on top.
This temporary barrier can remain in place until you return home.
Additional Vacation Plumbing Tips
If you’ll be away for an extended period, consider these additional precautions:
- Empty kitchen trash before leaving.
- Run the garbage disposal with plenty of water if your sink has one.
- Store food in sealed containers.
- Check for dripping faucets.
- Consider turning off the home’s main water supply if appropriate and if you’re familiar with the process.
- Ask a trusted neighbor or friend to check on your home during longer trips.
Will This Trick Work for Every Home?
Every plumbing system is different.
Homes with properly functioning drain traps may not experience odors even after several weeks, while factors such as climate, humidity, ventilation, and plumbing design can affect how quickly water evaporates from drains.
The paper towel and glass method is best viewed as a simple preventive measure rather than a guaranteed solution. If your home experiences persistent sewer odors, recurring insects, or drainage problems, it’s a good idea to have the plumbing system inspected by a qualified professional.
A Small Habit That Can Make Coming Home More Pleasant
Preparing your home before a vacation doesn’t always require expensive products or complicated routines. Sometimes, small preventive steps can make a noticeable difference.
Taking a few minutes to clean your sinks, freshen the drains, and cover them before you leave may help reduce odors and leave your kitchen and bathrooms feeling fresher when you return.
After all, coming home from a relaxing trip is even better when your home feels just as welcoming as when you left it.
