A simple gesture such as placing a full glass next to the sink prevents unpleasant odours that can ruin your return home after the summer break.

Summer is here, and with it, the long-awaited holidays. However, leaving your home for several days without taking precautions can turn your idyllic getaway into an unpleasant welcome.

An easy and inexpensive household trick promises to keep your kitchen fresh: leave a glass of water next to the sink before closing the door.

Why leaving a glass of water next to the sink prevents bad smells from the drain in summer

Have you ever come home and been surprised by a sewer smell in your kitchen or bathroom? The explanation lies in your domestic plumbing. The S-shaped siphon, that curve you see under the sink, acts as a hydraulic barrier: it retains a small amount of water to prevent sewer gases from entering the interior. The problem arises when the tap is not used for several days: the heat causes the water to evaporate and the “plug” disappears. Placing a full glass next to the drain, covered with a napkin or even a plate, slows down the evaporation process and blocks the escape of bad odours. This way, the water seal is maintained until you return.

Practical steps for placing the glass and sealing the drain before you go on holiday

Before packing your suitcase, follow this short guide and avoid unpleasant surprises:

  • Clean the sink and run hot water for a few seconds to remove any grease. Cover the drain with a paper towel or an upside-down plate, place a glass or bowl filled to the brim with water on top and repeat the process in the least used bathrooms (guest shower, bidet, etc.). That’s it! The seal is immediate and requires no chemicals.

These steps only take a couple of minutes. What’s more, you’ll find everything you need in your home, so there’s no extra cost. It’s easier than you thought, isn’t it?

Other plumbing precautions to take before leaving your home for the holidays

The glass trick is effective, but it’s not the only recommended measure. There are other equally simple actions that reinforce the protection of your plumbing:

Recommended action Main objective
Fill all drains with fresh water. Renew the hydraulic seal on secondary siphons
Visually check for possible leaks under sinks and washbasins. Prevent leaks that damage furniture or walls in your absence
Pour hot water with organic anti-grease products Prevent blockages and facilitate drainage after weeks of non-use

One last tip, and happy holidays!

Before you leave, check that all taps are turned off and that no appliances (dishwasher, washing machine) are left running. A kitchen free of leaks, odours and surprises will help you relax and ensure that your return home doesn’t spoil your summer memories.
