Drain stinks when the weather changes
A change in the weather and the drain odour reappears
An unpleasant odour from the drain when the weather changes can be very annoying. The typical odour, which is reminiscent of rotten eggs, becomes more noticeable especially when there is a sudden change in the weather or heavy rain. Other odours can also occur, but H2S, or hydrogen sulphide, remains the most common culprit. In addition to the unpleasant odour nuisance, this odour can also be harmful to health. With Roebic K67, this problem can be tackled effectively!
Why does the drain stink when the weather changes?
The odour from the drain when the weather changes is caused by the anaerobic decomposition of organic substances in the wastewater system, i.e., decomposition without oxygen. The dirt particles in the pipes settle on the inner walls of the pipes and decompose there. This produces gases, including hydrogen sulphide (H2S), which causes the foul odour.
Normally, these odours are held back by the siphon water lock. However, if the weather changes drastically, the air pressure in the sewer can fluctuate. This can force gases through the surge chamber, releasing the unpleasant odour into the rooms. As soon as the drain is used again, the surge chamber is restored, but the unpleasant odours often remain perceptible for some time.
What helps against the odour from the drain when the weather changes?
Roebic K67 can be a solution here. This product forms a protective layer on the inner walls of the drainpipes, which encases the trapped dirt particles. It also has a biological effect on the deposits. Unpleasant odours can be significantly reduced just a few hours after application.
When used regularly (as a maintenance dose), Roebic K67 biodegrades the deposits and ensures clean drainage pipes in the long term. Even the section after the siphon water lock is cleaned with prolonged use. Roebic K67 is a quick and effective solution against unpleasant drain odours when the weather changes.
Frequently asked questions
Why does my drain stink when the weather changes?
The odour is caused by anaerobic decomposition of organic substances in the wastewater system. This releases gases such as hydrogen sulphide, which cause the foul odour.
How does a change in the weather affect odour formation?
A sudden change in the weather, such as heavy rain or pressure changes, can change the air pressure in the wastewater system. This can cause odours to penetrate the siphon water seal and enter the rooms.
What is Roebic K67 and how does it help?
Roebic K67 forms a protective layer on the inner walls of the drain pipes to encase deposits. It has a biological effect on this layer and reduces odours quickly and in the long term.
