It is necessary to monitor the cleanliness of the room for hygienic procedures in order to prevent the appearance of an unpleasant smell of sewage from the sink and bathtub drain. In addition, if the water in the bathroom does not leave well, this can contribute to the appearance of fungus and mold, the active reproduction of pathogens. The most common reason for slowing down the flow of water is a sewage blockage, but sometimes water stagnates at the drain due to insufficient slope of the outlet drain pipe or the wrong cross-section of the sewer hole or drain pipe.
Mechanical clogging of pipes
Why does the water in the bath go bad? Mechanical blockage is a consequence of the ingress of various small objects into the sewer. The hair and hair of pets, sand and stones with dirty shoes, earth and clay with vegetables, coins and threads after washing clog pipes, a siphon and a bowl. The more debris accumulates, the slower the water goes.
Operational blockage
Why is water not leaving the bath well? The problem may be due to operational blockage resulting from ignoring preventive measures or during improper operation of the system. There are natural causes that make pipes worse over time. For example, it is cold water and fat. Soap or gel, which is used for everyday hygienic showers, is not enough to dissolve fat in the sewer pipes. Small debris also gradually accumulates, and a blockage forms. The situation is aggravated if you do not regularly clean pipes and plumbing with special detergents.
Man-made pipe clogging
Does the water in the bathroom sink go bad? This happens when there is a violation of the technology at the stage of construction work, wear of the main elements and in case of accidents on the communications. This includes the wrong angle of inclination of the outlet pipe, freezing or kink of the pipe, errors when choosing a site for laying communications, and the like. In this case, it is unlikely that it will be possible to eliminate the problems without the help of plumbers.
Proper blockage elimination
If the water in the bathroom leaves poorly, what should I do? You can only get rid of mechanical blockage on your own, but it is likely that this will not help or fix the problem for a short time. It is not enough to clean the pipes mechanically (with a plumbing cable or plunger) or using aggressive household chemicals.
Hydrodynamic cleaning is very effective, but for this it is necessary to supply water to the sewer system under pressure. Special hoses and a compressor will be required to ensure sufficient pressure. This is the fastest and safest way to clean pipes, but you will need to attract professionals.
In practice, only an integrated approach to the problem will help eliminate blockage and forget about it in the future for a long time. Cleaning the drainage system is inseparable from measures to clean the sewer pipe, because small debris is not distributed locally in one area, but along the entire length of the sewer riser and the discharge pipe. You can do everything yourself.
Cleaning the drain and siphon
Small debris, which turns into rotting sludge or mold, emanating a fetid odor, is usually collected in sewage and siphon. To clean these areas, you need to remove the siphon, unscrew the mesh that holds the tube. The entire contents of the siphon must be thrown into the toilet and rinsed several times. Bowls, all inner tubes, gaskets, mesh and siphon should be washed well under running water with a degreasing agent. It's okay if there is no special detergent for plumbing. Effectively dissolves fats and removes dirt from ordinary dishwashing detergents.
Mechanical cleaning
If water still drains poorly into the bathroom drain, you need to mechanically clean the sewer pipes. This is done before installing the siphon and other parts of the system. It is best to use a plumbing cable that is screwed into the system. To remove debris, the cable must be pulled out and cleaned periodically. It is necessary to push it until the blockage is completely eliminated. When the garbage is removed, the water will begin to drain normally.
To clean the system with a plunger, you need to fill the bath with water so that the valve is completely hidden. Previously, it is better to cover the space around the film and change into overalls - the work can be dirty. The drain hole must be covered with the rubber part of the plunger, and then begin to press on the handle in order to push the blockage into the pipe along with stagnant water. To flush the system as best as possible, after removing the blockage, it is advisable to refill the bath with hot water and lower it.
Household cleaning
After performing all of the above actions, it remains only to clean the sewer system with household chemicals. A bag of detergent that breaks down fats, softens plaque and kills pathogens, needs to be emptied into the sewer. You need to leave it for 15-40 minutes (the exact time is indicated in the instructions for the detergent), and then rinse the pipes with running hot water for 10-15 minutes.
Incorrect pipe slope
If the water in the bathroom does not leave well, but there is no blockage, then the cause of the problem is most likely a violation of the technology of plumbing. Perhaps the slope of the pipe is insufficient, so that the draining water does not reach the socket. This is determined visually. To increase the slope of the pipe, you need to lower or raise the bath.
The standard maximum slope is 15%. The optimal value is 30-50 mm per meter of pipe. With slopes of less than 15 or more than 60 mm, the likelihood of clogging is significantly increased. In addition, it is not recommended to install corner elements at 90 degrees when laying the system. If necessary, it is better to set two turns at 45 degrees.
Insufficient cross-sectional size
Does the bath water go bad? If the “wrong” pipes are installed, you will have to change the entire system so that you no longer face the problem of constant blockages. Previously, designers were generally limited to three sections: 150 mm cast iron pipes were rarely used inside buildings, from 100 mm cast-iron pipes were assembled, and the rest was assembled from 50 mm. Today, the product range has expanded significantly. In most cases, the pipe diameter and configuration are selected based on recommendations and regulatory requirements.
For internal networks, any available diameter of cast-iron (50, 100, 150 mm) or plastic (16-160 mm) sewer pipes can be used. A cross section of 32 mm or more is suitable for a washbasin in a bathroom where fats do not merge. For a kitchen sink, draining the bathtub and shower, washing machine and dishwasher, you need a pipe of at least 40 mm in diameter. For combined draining of the bathtub and shower, it is better to choose 50 mm, more than three devices without a toilet are connected to a horizontal “lounger” 60 mm, more than five devices are 75 mm, the toilet and vertical risers are 100-110 mm.
Blockage prevention
Does the bath water go bad? After a comprehensive cleaning of the system, it is necessary to carry out preventive measures from time to time so that the problem does not occur again and again. You can install filters and grids (grilles) on the drain, which reliably protect the interior of the plumbing from small debris. Every few days, you need to rinse the system with hot water to protect the pipes from the accumulation of fatty deposits. In addition, plumbing needs periodic preventive cleaning (both mechanically and by household chemicals).
