4. Refill the P-Trap
Run water through every sink, shower, tub, and floor drain for about 20 seconds.
Don’t forget to flush every toilet as well.
This is the single most important step because it restores the protective water seal inside each P-trap.
5. Dry the Sink
Wipe away standing water with a clean towel.
Keeping surfaces dry reduces moisture that can contribute to mildew growth.
6. Cover the Drain (Optional)
If you’ll be away for several weeks, you can place a paper towel over the drain and cover it with an upside-down glass as an additional barrier.
Alternatively, you can use:
- A sink stopper
- A rubber drain plug
- A silicone drain cover
- Plastic wrap secured with painter’s tape
The goal is simply to reduce airflow through the drain opening.
Extra Vacation Plumbing Tips
If you’re leaving for an extended trip, consider these additional precautions:
- Empty trash cans before leaving.
- Clean your garbage disposal thoroughly.
- Check that all faucets are fully turned off.
- Shut off the home’s main water supply if appropriate.
- Ensure basement drains have water in their traps.
- Ask a trusted neighbor to periodically check your home if you’ll be gone for several weeks.
These small tasks can help prevent unpleasant surprises when you return.
Frequently Asked Questions
How long does it take for a P-trap to dry out?
In most homes, a P-trap can hold water for several weeks. Hot weather, dry climates, strong air circulation, and infrequently used drains may cause water to evaporate more quickly.
Does the upside-down glass trick really work?
It may help reduce airflow through the drain, but it isn’t considered a complete solution. Keeping the P-trap filled with water remains the most effective way to prevent sewer odors.
Should I pour bleach down my drains before leaving?
Generally, no. Bleach isn’t necessary for routine vacation preparation and may damage plumbing if used excessively. Cleaning with vinegar or simply flushing with fresh water is usually sufficient for routine maintenance.
Can insects really come through sink drains?
Some insects, including drain flies and certain cockroaches, may enter through plumbing systems if conditions allow. Maintaining water-filled P-traps helps reduce this risk.
Is this necessary for a short weekend trip?
Usually not. Most P-traps retain enough water for short vacations. These precautions become more valuable when you’ll be away for several weeks or longer.

Final Thoughts
Preparing your sink before leaving for vacation only takes a few minutes, but it can help prevent unpleasant odors and keep your home feeling fresh when you return.
The most important step is making sure every drain’s P-trap contains fresh water. If you’d like extra peace of mind during a longer trip, covering the drain with an upside-down glass or a proper drain cover may provide an additional layer of protection.
Sometimes the smallest home maintenance habits make the biggest difference. Add your sinks to your vacation checklist, and you’ll be one step closer to returning to a clean, fresh-smelling, and worry-free home.
