Persistent smell of sewage in the bathroom, mold, dampness: 4 mistakes in repair (reasons and what to do)

A person always reacts to smells. The atmosphere in the house should not smell like a sewer, but pleasant aromas from the kitchen or aromas.

Often apartment owners notice that after the renovation of the bathroom, a not very pleasant smell has appeared. I would like to invite friends and relatives, but how to solve this problem?

Sewer air not only not pleasant, but also harmful. It includes methane, hydrogen sulfide and ammonia. Some even develop anxiety, irritability from such a “scent”. Prolonged exposure to sewer odor can impair human health.

Blockage

Hair, small debris, threads, dirt accumulate inside the pipe and do not go away. The blockage narrows the space in the pipe and impairs the flow of water through the pipes. Air from the sewer begins to see through the smallest cracks, pipeline joints, siphon.

Cleaning of pipes and siphons is carried out using a cable and a plunger. If the blockage is large, use the first tool. But when there is no cable, and the blockage needs to be removed urgently, many use folk remedies: soda and citric acid. They are good for small blockages.

To prevent the pipes from clogging up in the bathroom, and the siphon, I use homemade fixtures from a plastic bottle.

I cut it so that there is a ring on top for easy removal of the hair catcher from the drain. Hair sticks to the notched plastic strip and does not get inside. Then I just throw it away and cut new ones. Forgot about the blockage forever.

There are also chemical remedies for blockages, but if left to fill for a long time, it can harm plastic pipes, a siphon. Therefore, do not use the products for longer than indicated on the bottle.

Sealing and waterproofing

Use a sanitary sealant to seal all gaps. It is sanitary, because fungicides are added to it (against fungus).

Lack of a waterproofing layer. If a leak occurs, water will accumulate on the floor and the flooring will rot.

Other errors

Often, an unpleasant smell appears due to design errors in the sewage system. The required slope of the pipes has not been made (2-3 cm. per 1 meter of pipe length).

If too great a slope is made, then the liquid will fill the entire space of the pipe, and a vacuum will be created, which will lead to the suction of the liquid from the siphon water seal. As a result, all vapors from the pipes will go straight into the room.

Better to install immediately siphon with dry seal. It is a durable plastic tube with a check valve inside. There will be no smell.

Ventilation

It is not difficult to find out whether the ventilation is working correctly or not. Take an ordinary piece of paper, open a window in any room, and bring the piece to the ventilation grill.

He should kind of stick to her. So the ventilation works fine. Can be checked with a lighter. If the light is directed towards the ventilation, then everything is fine. If not, then the reason is in her.

Musty air, mold in the bathroom Is the main reason for poor ventilation. If there is mold and mildew in the corners, between the tiles, there is an unpleasant smell, then it is necessary to install forced ventilation.

Call a professional to install an exhaust fan.
