The drain gurgles – causes and countermeasures at a glance
A drain that makes gurgling noises is not only annoying and annoying, it usually also hides a technical defect within the sewage system. Therefore, a gurgling drain should not be ignored, because the drainpipe is often completely or partially blocked. Depending on the degree of constipation, home remedies can provide temporary relief. In the case of worse blockages that are deeper, especially if the water escapes upwards or disgusting smells are spreading, then professional help should be sought immediately. Otherwise, there is a risk of worse consequential damage, which leads to even more costs.
How does the “gurgling noise” come about in the drain?
The typical gurgling is created by your negative pressure in the drainpipe of the sewage system. Normally, the air that pushes the running water in front of it moves back above the body of water. But if the pipe is partially blocked, then the water builds up in front of this constriction and only flows away slowly. Underneath the blockage, an overpressure is created, which slowly dissipates in the form of air flowing up through the water column. This creates the characteristic gurgling. These blockages are usually triggered by various deposits such as lime, grease, hair, or even food scraps that accumulate over the years. If the characteristic gurgling occurs, for example, after an extensive rainfall, the problem may be directly in the sewer system. Like other wastewater, rainwater also reaches the sewerage system via gullies. In such a case, you should not experiment yourself and seek advice from a specialist immediately.
It is best to proceed as follows:
- – First of all, a sufficiently large bucket should be placed under the siphon. It is also advisable to have a towel or rag ready.
- – Then the union nuts on the washbasin and drain side must be opened. If this does not work by hand, water pump pliers can help. However, this should be used carefully, otherwise, the plastic nuts can easily break.
- – Pull off the siphon and tip the excess water into the bucket and remove dirt from the siphon with a brush and cleaner. The wall inlet can also be cleaned with a brush or spindle.
- – When reinstalling the siphon, new seals should be used. If there are none, the old ones should at least be freed from limescale deposits with vinegar water.
A vent that is blocked by birds or that is not functioning properly can also be the cause of a gurgling, usually accompanied by unpleasant smells. If available, the ventilation nozzle is located on the roof of the house. An empty pipe leads into the interior of the sewage system. This venting is responsible for ensuring that enough air flows into the system when the water is running out, thus avoiding a negative pressure that would empty the siphon. As a result, its water reserve would be sucked empty and odors from the sewage system would enter the room.
Remedy from the clucking – this can be done
As soon as a gurgling is perceived, there should be no hesitation. This is the only way to solve the problem quickly and without consequential damage. First of all, the source of the cluck must be found. But you shouldn’t act too hastily, because a gurgling sink does not necessarily have to be caused by a clogged sink siphon. Since all pipes in the apartment or house lead into a collective sewer system, it should be checked carefully where the noise actually occurs when water is flushed into the system. If the sound is heard at the same point as water is being brought into the system, then the blockage is mostly near the drain. Here, simple home remedies can initially be used as problem solvers. The siphon should be dismantled and checked for any soiling and cleaned accordingly.
Home remedies and the chemical club
Also, hot water in conjunction with a suction cup can often work wonders. Baking powder, salt, or vinegar are also often used to cope with constipation. Care should be taken when using a chemical pipe cleaning agents from specialist dealers. Because these often form caustic soda in connection with water. This not only releases polluting vapors and damages the environment, but in the worst case, it can also damage the seals of the sewer pipes. This in turn can lead to expensive water damage in the home.
If the pollution is deeper, the professional has to work
If the gurgling is heard from another drain where water is not being flushed in, then the blockage is probably deeper in the pipeline system. The use of conventional home remedies is futile here. A pipe cleaning spiral is usually used here. This is a spiral-shaped wire that is carefully inserted into the sewer pipe and is intended to loosen the dirt there by means of mechanical force. Since their use requires professional knowledge, otherwise there is a risk of damage and consequential damage, a professional should definitely be called in here. This can also replace entire pipe bends or pipe sections in the case of really stubborn dirt such as extreme limescale deposits.
In principle, if the above-mentioned, non-critical home remedies fail, it is advisable to call in a specialist such as a plumber in UK. This avoids expensive consequential damage. With the help of the craftsman’s experience, the cause is localized quickly and efficiently and the problem is resolved gently and purposefully.
