Absences of several days require small precautions at home. There is a quick gesture, made with objects that everyone has at hand, capable of reducing the risk of bad odors upon return. It’s discreet, cheap and easy to repeat whenever the house is closed.
The simple gesture that makes a difference
The idea is to create an additional barrier to the passage of odors down the drain. According to the German news portal, all you need to do is use a glass of water and a small weight to temporarily seal the sink opening, preventing the smell from spreading throughout the kitchen.
For greater effectiveness during prolonged absences, it is possible to replicate the same procedure in other drains that are rarely used in the house, such as the sink or shower in the bathroom. The objective is to standardize protection in less used water outlets, reducing the likelihood of odors upon arrival.
How to apply, step by step
The procedure is straightforward. According to the source mentioned, first place a napkin over the mouth of the drain. Then, place a glass full of water on top or, alternatively, an upside-down plate. This light weight limits air entry and slows evaporation from the water seal.
Why it works: the function of the siphon
In domestic drains there is a siphon with a “U” shape that retains a small amount of water. This liquid “lid” blocks the rise of gases from the collector into the home, fulfilling an essential safety and comfort function.
When the house remains unused for days
Prolonged lack of use can lower the water level in the siphon through evaporation. In this circumstance, the protection loses effectiveness and odors become noticeable. By limiting air circulation in the drain, the recommended method helps to preserve the water seal for longer.
Alternatives and prevention
There are complementary measures that reinforce the same objective, explains the website. Filling the various drains with water before leaving and checking for leaks or blockages are prudent habits. Preventive maintenance with hot water and eco-based cleaning products also helps keep the pipes in good condition.
For those who prefer not to leave glass on the counter, there are silicone or rubber drain covers that create a soft, reusable seal. They are easy to wash, take up little space and can replace a cup or plate when you are away, as long as they are only placed when the drains are not in use.
And if the smell has already appeared
If the odor is already noticeable when you return, cleaning the drain and checking the siphon usually resolves most situations. The same publication reminds us that there are also homemade unblocking tricks for small accumulations, which can be applied when necessary.
