Before leaving for vacation, most people remember to lock the doors, close the windows, and switch off appliances. However, one small part of the home is often forgotten: the sink. When plumbing traps sit unused for several days, the water inside them can slowly evaporate, especially in warm weather. This water normally helps block sewer gases, so a dry trap can allow unpleasant smells to enter the house. Unused drains may also attract small insects searching for moisture.

The good news is that preventing the problem takes only a few minutes. Shortly before leaving, run water through each sink so the plumbing traps are filled with fresh water. For an unused drain, you can also add a temporary barrier. An upturned glass placed over the drain can help keep unwanted odors and insects from entering while you are away. A small piece of paper can be placed nearby as a reminder to remove the cover when you return.

For longer vacations, remember that sinks are not the only drains that can dry out. Bathroom sinks, showers, tubs, and floor drains may also have traps containing water. Checking these areas before leaving can help prevent unpleasant odors throughout the house. It is also a good idea to clean and dry the surrounding areas.

There is no complicated secret behind this simple trick. It is simply basic home maintenance that is easy to overlook. As the original article explains, **”Sometimes, the smallest preparations are the ones you appreciate most when you finally walk back through the door.”** Taking a few minutes before your trip can help ensure that your home smells fresh and feels comfortable when you return.
