After the house was installed, I was very happy when I first lived in it, but the bathroom suddenly leaked, and the joy disappeared. This was followed by lengthy repairs, and due to the different decoration methods, the treatment methods were also different.
Toilet leaks are often blamed first on lack of waterproofing, but this is only one of many reasons, and it is especially common and well-known. However, the source of the water leak can come from multiple sources. Xiaobian deeply analyzes the key parts of the toilet leakage, not only limited to waterproofing, but also provides detailed solutions to help you avoid treatment mistakes and reduce trouble!
1. Waterproof
When the bathroom leaks, people first think of the lack of waterproofing of the wall and floor, which is indeed reasonable, because waterproofing is the key to ensuring that the bathroom does not leak. However, even after the closed water test, why does the water still leak? In fact, it is caused by improper materials and construction methods, which is the root cause of water leakage in the bathroom due to waterproof problems.
(1). Waterproof material
There are many waterproofing materials in the bathroom, and the combination of "hard walls and soft floors" is the best choice at the moment to ensure that the waterproof function is maximized. Brand selection is also crucial, and only big brand waterproof products can ensure that "no water leaks". The problem of water leakage after moving in some bathrooms often stems from the quality and improper matching of waterproof materials, which needs to be paid attention to.
(2). Waterproof construction method
Waterproof construction needs to follow the principle of "wall rigidity and soft floor" and be implemented step by step. The wall is waterproof first, and then the tiles are pasted; After the wall is completed, the ground can be treated, waterproof construction can be carried out, and the closed water test is strictly carried out. This step-by-step operation ensures that the ground is protected from damage during the construction process, maximizing the protection of the integrity of the floor's waterproofing layer and thus effectively preventing water leakage.
Some people are accustomed to completing the wall and floor at one time when doing waterproofing, and then laying the wall tiles. However, in this process, construction tools, ladders and other items slide on the ground, which is easy to cause potential damage to the waterproof layer, and it is difficult to detect at the beginning. After moving in, as the amount of water consumption increases, the problem of water leakage gradually appears.
Editor's suggestion:
If the leakage in the bathroom is due to a waterproof problem, there is no need to hesitate to directly remove the floor and redo the waterproofing to cure the problem. The so-called "brick-free waterproofing" on the market only temporarily alleviates the surface water leakage, but fails to solve the fundamental problem, and needs to be carefully chosen.
2. There is no waterproof plugging around the threshold stone
Soon after moving into a new house, do you notice that the wall at the door of the bathroom is getting damp? At first, it is suspected that it is caused by mopping or improper use, but the increasing humidity is actually a sign of water seepage in the bathroom. The root cause of the problem is that the waterproofing under the threshold stone is not perfect, and the stagnant water seeps out from it, causing the wall to be damp.
Editor's suggestion:
Before the waterproofing construction of the bathroom floor, be sure to pave the threshold stone first. When waterproofing, it is necessary to use a plugging material to professionally plug the leakage under the threshold stone, and then carry out ground waterproofing simultaneously to ensure that the bottom of the threshold stone is also completely waterproofed and form an integrated waterproof layer, so as to eliminate the problem of water seepage under the threshold stone.
3. Leaking water pipes
Although it is said that the bathroom is leaking, it does not mean that it is a waterproof problem, and in some cases, the cause of water leakage is the cause of the water pipe. The causes of water pipes often come from two aspects, namely:
(1). There is a leakage problem in the water pipe provided by the developer
Although some developers have pre-installed some water pipe points when handing over the house, some owners choose to use it directly in order to save costs. However, due to the influence of water pressure after moving in, the water pipes are prone to leakage and bursting joints, resulting in water seepage from the wall to the downstairs bathroom. At the root of the problem, these water pipes are engineering pipes, and their quality is not guaranteed, and they are only suitable for temporary use, not long-term home use. If it is not replaced during decoration, the risk of leakage in the later stage is high, which directly causes the problem of water leakage in the bathroom downstairs.
(2). The new water pipe used in the decoration has a leakage problem
Although some developers have pre-installed some water pipe points when handing over the house, some owners choose to use it directly in order to save costs. However, due to the influence of water pressure after moving in, the water pipes are prone to leakage and bursting joints, resulting in water seepage from the wall to the downstairs bathroom. At the root of the problem, these water pipes are engineering pipes, and their quality is not guaranteed, and they are only suitable for temporary use, not long-term home use. If it is not replaced during decoration, the risk of leakage in the later stage is high, which directly causes the problem of water leakage in the bathroom downstairs.
Editor's suggestion:
When decorating, it is necessary to choose high-quality water pipes, and the concealment of hydropower projects is strong, and the quality of materials cannot be compromised. After the installation of the water pipe, be sure to ask the merchant to carry out a pressure measurement, the pressure measurement time is at least 30 minutes, the test pressure is at least 6 kg, 8 kg is recommended, and the electronic and manual pressure measurement are parallel to ensure that nothing goes wrong. After the pressure measurement is qualified, protect the water pipe in time to avoid construction damage.
4. Leaking sewer pipes
The leakage of water in the bathroom downstairs turned out to be the cause of the sewer pipe, although it is not common, but it does happen. And the sewer pipe leakage is also divided into two situations, namely:
(1). The original main sewer pipe is leaking
When decorating, it is necessary to choose high-quality water pipes, and the concealment of hydropower projects is strong, and the quality of materials cannot be compromised. After the installation of the water pipe, be sure to ask the merchant to carry out a pressure measurement, the pressure measurement time is at least 30 minutes, the test pressure is at least 6 kg, 8 kg is recommended, and the electronic and manual pressure measurement are parallel to ensure that nothing goes wrong. After the pressure measurement is qualified, protect the water pipe in time to avoid construction damage.
(2). Leakage of new sewer pipes
Since the location of the sewer pipe of the developer may not meet the renovation needs, the renovation often needs to be adjusted and the sewer pipe needs to be relaid. However, during the construction process, there may be leakage after prolonged use due to improper application or omission of PVC adhesive or damage to the pipes. As the water accumulates, leaks can spread downstairs. Therefore, it is necessary to ensure that the glue is applied in place during construction to avoid damage to the pipes and ensure the reliability of the sewer system.
Editor's suggestion:
When decorating the house, be sure to carefully check the sewer pipes preset by the developer, especially the joints, and confirm that they are correct before closing. Newly laid sewer pipes are also subject to a test drain test to ensure that the sewer system is not leaking after confirming that they are unblocked.
5. The bathroom installation is not in place and leaks
Bathroom equipment in the bathroom is indispensable to meet daily needs. However, if the installation of bathroom equipment is not done properly, it is very easy to cause leakage, and the accumulation of stagnant water may even leak downstairs, so the quality of the installation is crucial.
(1). The angle valve is not installed in place
Angle valves are indispensable water connections in kitchens, bathrooms and balconies. Due to the embedded position of the raw water pipe and the length of the angle wire, the installation of the angle valve is often not in place, resulting in water leakage in the bathroom. This kind of water leakage was difficult to detect at the beginning, until the residents downstairs reported that the cause was finally determined after many investigations. Therefore, special care should be taken when installing angle valves.
(2). The shower is not installed in place
The installation position of the shower is similar to that of the angle valve, and it needs to be precisely connected to the inner wire elbow of the water pipe in the wall. However, some installers only operate according to their personal habits rather than following the installation standards, resulting in improper installation of angle valves at the shower position. The problem was discovered when the wall was damp, and the water leaked downstairs. Therefore, strict standards must be followed during installation to ensure quality.
Editor's suggestion:
After the water pipe is pressed, the position and depth need to be accurately controlled when fixing to ensure that after the tile is laid, the inner wire elbow is flush with the tile or only 2mm lower. This detail ensures a smooth connection between the angle valve and the shower during installation and is key to the quality of the installation.
Finally, I would like to summarize it for you:
Toilet leakage is not only caused by insufficient waterproofing, but also the lack of waterproof plugging of sill stones, leakage of water pipes and sewer pipes, and improper installation of bathrooms are also common causes. It's important to pay attention to these details when renovating to ensure worry-free restrooms and maintain a harmonious neighborhood relationship.
