Problems with water trap

The bath is connected to a common sewage system using a flexible pipe called a siphon or a water trap. The siphon always has a curved shape and a drop so that dirty water does not pour back.

Important! A water lock is also formed in the siphon, which prevents the smell from the sewer. If this obstacle disappears for any reason, then there is the smell of sewage in the bathroom.

For what reason can problems with the siphon occur? There can be several such reasons:

• Over time, the corrugated part of the siphon can lose its original stiffness, elasticity, stretch, sag. Water ceases to accumulate, thus, a water lock disappears, which holds back the amber from the sewer.
• Another cause may be improper installation of the water seal. Mount plumbers will come, they will install a siphon, for example, in an inverted form or a corrugated pipe is greatly stretched.
• With prolonged downtime, the stagnant water inside the siphon begins to evaporate, creating an unpleasant odor.
• With prolonged use, dirt, hair, grease settle on the walls of the siphon. All this leads to an unpleasant odor from the bathroom drain.

Important! These reasons are easy to eliminate:

• It is necessary to disassemble the siphon, clean it of dirt, bring the corrugated part to its normal position, and check whether the parts of the hydraulic seal are fitted tightly.
• If the siphon has fallen into disrepair, it must be replaced.
• If you have not used the bathroom for a long time, you need to drain the water from the siphon.

Impaired air circulation

In a bathroom, which is a constantly humid room, good ventilation is very important. It not only eliminates odors, but also dries the air, reducing the amount of condensate. It is easy to determine how the hood works - for this you need to bring a sheet of paper to it:

• A well-functioning hood will draw a sheet.
• If the paper falls to the floor, it means that the duct is jammed. It should be cleaned and air circulation restored.

Important! If it seems to you that the smell does not come from you, but from the neighbors, then you should call the masters from the Housing Office. Maybe the common ventilation shaft is clogged. Sometimes birds or mice get there.

Condensation or leakage

Do not exclude the possibility of leaks and condensation. It is very difficult to determine the place of condensation in such a small room, like a bathtub, where there are many types of plumbing:

• Check if the water falls into the laundry basket, on the shelves with cosmetics. If water gets there, it can rot and create an unpleasant odor.
• Leaks can be in hard-to-reach places: behind the washing machine, under the sink.

If you do not pay attention, the water will eventually destroy the floor and reach the neighbors. And repair will not do.

Important! When repairing in the bathroom, do not install tees and pipe joints in hard-to-reach places. It is best to bring one pipe under each plumbing fixture. Less connections - less leaks.

If condensate nevertheless accumulates in an inaccessible place, then there is a simple way out - to get to this place somehow and insulate its walls and pipes so that the temperature remains more or less the same.

Pipe coating

One of the possible causes of the smell of sewage in the bathroom is plaque on pipes, which reduces their inner diameter and disrupts the circulation of water. This problem most often occurs if the apartment has cast-iron pipes. In this case, clean the sewer. To do this, you can use a variety of methods and means - from plumbing cable and plunger to modern chemicals from blockages and folk remedies such as soda, vinegar.

Wrong pipe selection during repair

If pipes of a smaller diameter than normal are installed during repair or improper installation is done, this can also lead to an unpleasant odor. Here, apart from changing the plumbing, nothing will save you.

Washer

Sometimes the cause of this kind of trouble can be a washing machine. This can happen if the drain hose is inserted after the water seal. Then the aroma will seep through the drum of the washing machine.

Depressurization of pipe connections in the bathroom and toilet

One of the common causes of stench in the bathroom and toilet may be the partial depressurization of pipes. How, then, to eliminate the smell from the sewer in the bathroom and toilet?

• It is necessary to cover the joints with sealant or silicone.
• Sometimes it is enough to replace the rubber o-rings in the sewer sockets.

Important! All cracks in the siphon and pipes must be properly wrapped with sealing tape and treated with silicone.
