How to quickly find the leak point, the easiest way to check the leak point

Generally, it can only be dug up and checked, and there is no instrument to detect water leakage without damage. There are several ways to check this:

1. The original pipeline diagram is judged according to the installation position of the water supply pipe and drainage pipe.

2. The leakage part is generally at the leaking water pipe, but it often leaks far along the electric pipe and other pipes.

3. When the amount of seepage is relatively small, you can wipe it dry and observe the seepage point by sprinkling cement.

1.First, confirm the leakage site, find the root cause of the leakage, and divide it into waterproof layer, hot and cold water pipes, medium water pipes, heating pipes, and upstairs and upper and lower water pipes.

2.The first step is to do a pressure test on the water pipe to see if the pressure is dropped.

3.The second step is to do a 24-hour closed water test in the bathroom to determine the waterproof layer.

4.The third step is that if the water pipe is leaking, it can be repaired or the water pipe can be changed to an open pipe without damaging the waterproof layer.

5.The fourth step is that if the waterproof layer is leaking, the treatment plan is to put the wall and floor tiles, sanitary ware, and ceiling of the bathroom.

Wait for dismantling, re-do waterproofing, generally three times, and then do a closed water experiment, the construction period is about 15 days.

Causes of water leaks in the home.

1. There is no insulation layer.

If it is an old house, it may not be insulated, and the walls of the previous residences are basically without insulation. In winter, the temperature difference between indoor and outdoor is large, so the wall is cold on the outside and hot on the inside.

Due to the high temperature of the interior walls, condensation will form on the walls.

Causing the wall to be damp, and it is a whole wall, such a situation generally only appears in winter, and it will be better in summer, but there are sequelae.

That is, it will leave a lot of unsightly mildew, which will affect the appearance of the wall.

2. Improper paint construction.

We all know that the paint must be dried before the next process can be constructed, if there is no correct construction, it is easy to cause the water vapor in the wall to fail to volatilize, causing the wall to be damp.

3. Waterproofing is not in place.

The upstairs neighbor's floor was not waterproofed well, especially in the bathroom and kitchen, causing water to leak into the downstairs wall.

The junction between the upstairs water pipe and the ground is not waterproofed, and it is very likely that there will be water seepage near the pipe, and the water will flow down the water pipe, resulting in water seepage on the roof.

4. Leakage of water pipes in the wall.

The water seepage of the wall of many owners' homes is caused by the leakage of the water pipe in the wall, and the leakage of the water pipe will directly cause the wall to be damp. Generally, this situation mostly occurs near the bathroom, or on the roof or wall of the house. It may be that there is a leak in the part of the embedded water pipe joint, or it may be a leak in the wall of your own home or upstairs.

The easiest way to check for leaks:

1. Find the leakage point from the high part of the roof to the low part to see if there are cracks on the roof, if there are cracks, it means that there will be water leakage here.

2. You can see the damage of the waterproof layer of the roof, and see that the water flows from the **.

3. Usually the water leakage will be more damp, and there are traces of dripping, if the water leakage is not easy to detect, you can use a special testing instrument to detect, you can quickly find the water leakage point.

Common problems with water leaks in the house:

1. Water leakage on the wall.

Water leaks on the walls are a common problem, and wall leaks are mainly caused by peeling off of the coating. This condition not only affects the aesthetics, but also causes water leakage in the room. Water leakage on the wall is generally caused by the developer cutting corners and not adding waterproofing materials when using cement slurry bonding.

2. Roof leakage.

The problem of roof leakage is also very common, which is mainly caused by poor construction quality, when building a house, the construction personnel are not up to standard, and the materials are not qualified, which will lead to roof leakage.

The easiest way to check the leakage point is generally to use the way of the pressure test, first close the main valve of the water pipe at home, and then use the manual pressure machine to carry out the water pipe pressure experiment, when there are 8 to 10 kg, it should be placed for half an hour to stop the water pipe, wait until the surface of the pipe is cooled down and then inject hot water into the pressure, and then close the valves of each pipeline on the water separator, check the change of the pressure gauge, if the circuit pressure is lowered, it is said that the water leakage. After finding the leakage, chisel the wall to repair the leakage point, the leakage is serious, usually replace the water pipe, pay attention to the waterproof hidden measures in the pipe and the wall should also be in place, so as to avoid the problem of water leakage in the old stove again.

The way to find the leakage point of water leakage is to suppress and check the gaps in the pipe.

1. The way of suppression

To find the leakage point by suppression, first let the plumber come to the door to conduct a pressure test on all the pipes in the home, and soon find the specific leakage point and repair the work.

2. Check the gaps in the pipeline

If no water leakage is found in the pressure test, it is necessary to check the gap in the pipe, or check whether there is any water leakage at the floor drain, and if so, the local waterproofing needs to be redone.

Causes of water leaks in the house

1. The pipeline is damaged

One of the most direct reasons for water leakage in the house is that there are cracks and damage in the pipes, and the water will flow out directly through the gaps in the water pipes when it passes, even if it is an inconspicuous small crack, it will cause serious water leakage over time, so that the water stains on the wall are obvious, damp and mildew, and in serious cases, it will also cause the wall to drip and even affect the residents downstairs.

2. Water leakage upstairs

The main manifestation of the upstairs leakage is that there are obvious water stains on the ceiling of the downstairs house, and even water droplets continue to leak. This situation is most likely due to a large area of overflow in the bathroom or other ground of the upstairs resident, and the waterproof layer is damaged, so the water will leak downstairs.

3. Water leakage on the top floor

If the top floor of the house is leaking, then it is basically a problem with the waterproof layer of the roof. If it is within the warranty period, you can reflect it to the property, and generally there will be a special person to come to repair, and if the water leakage is serious, you can apply to start the overhaul**, but the premise is that all owners need to agree. If the warranty period has expired, then you can only repair it yourself.

There are several ways to detect water leaks:

1. Environmental Investigation Method.

One of the most intuitive ways to determine the clues and extent of water leaks. According to the water supply network diagram and the information provided by the relevant personnel, a detailed investigation of the water supply pipeline is carried out. This includes the connection, distribution, material and surrounding media of the pipes.

The leakage point was determined by observing the road surface conditions, the snow melts first in winter, the vegetation above the pipeline, and the long flow of clear water in ditches such as wells.

2. Stress test comparison method.

If the pipeline is damaged and leaking, if the leakage is large, it will generally cause the local pressure of the pipe network to decrease, and the closer to the leakage point, the lower the pressure. Pressure measurement comparisons using fire hydrants allow for quick locking of leaking areas.

3. Residual chlorine detection method.

According to the factory water standard stipulated by the state, the residual chlorine content of chlorine and water after 30 minutes of contact should not be less than milligrams, and the content of free residual chlorine in the water at the end of the pipe network should not be less than milligrams. Using the principle of residual chlorine and o-toluidine to form yellow quinone compounds, the water samples collected can be tested to determine whether there is a leak in the water supply network by visual color comparison.

4. Leakage noise technology detection.

Leakage noise-related technology has been used as a method for water leakage detection for more than 20 years, and with the development of microelectronics, the design and performance of correlators have come a long way in these years. Leakage noise-related technology works by placing a sensor on each side of the suspected leakage, receiving the leakage noise, and then determining the time difference between the two sensors.

Knowing the distance between the two sensors and the speed at which the sound travels through the pipe, it is possible to accurately calculate the location of the missing silver point.

1.First, confirm the leakage location and find the root cause of the leakage, which is divided into a waterproof layer, a hot and cold water supply pipe, an intermediate water supply pipe, a heating pipe, and an upstairs water supply pipe.

2.The first step is to do a pressure test on the water pipe to see if the pressure is negative.

3.Step 2: Do a 24-hour closed water test in the bathroom to determine the waterproof layer.

4.Step 3: If the water pipe is leaking, it can be repaired or changed to an open pipe without damaging the waterproof layer.

5.Step 4: If the waterproof layer leaks, the treatment plan is to remove the wall, floor tiles, sanitary ware, and ceiling of the bathroom, and re-do the waterproofing, usually three times, and then do the closed water experiment. The construction period is about 15 days.

Causes of water leaks in the home.

1.There is no insulation.

If it is an old house, it may not have an insulation layer, and the previous residential walls basically did not have an insulation layer. In winter, there is a large temperature difference between indoor and outdoor, so the outside of the wall is cold and the inside is hot. Because of the high temperature of the interior walls, condensation will form on the walls, causing the walls to be damp and the entire wall.

This kind of situation generally only occurs in winter, and it will be better in summer, but the sequelae is that it will leave a lot of unsightly mildew, which will affect the beauty of the wall.

2.Improper application of paint.

When painting, we all know that it needs to be thoroughly dried before the next process can begin. If the painting is not done correctly, the water vapor inside the wall will not evaporate, which will cause the wall to be damp.

3.Waterproofing is not in place.

The floors of the upstairs neighbor's house were not properly waterproofed, especially in the bathroom and kitchen, causing water to leak into the wall downstairs.

The connection between the upstairs water pipe and the ground is not well waterproofed. There is a high probability that water is seeping near the pipes, and the water is flowing down the pipes, causing water to seep into the roof.

4.Leaking water pipes in the wall.

Many owners' wall seepage is due to leaking water pipes in the wall, which will directly lead to dampness in the wall. This usually happens near the bathroom, or on the roof or wall of the house. It may be that there is a leak in the embedded water pipe joint, or it may be a leak in the water pipe of your own home or the wall of the upper floor.

Kiss, <>

We're glad to answer your questions! You can do a 24-hour closed water test to clear potatoes, mainly to determine whether the waterproof layer can be waterproof. If the surface-mounted water pipe can wipe the water on the surface, and then observe the seepage point on the **, the concealed water pipe can observe the ceiling, wall and other positions, and the place with water stains and watermarks is the leakage point.

Look at the location of faucets, water pipe joints, or installed fittings, most of which are prone to water leakage, so a closer inspection will reveal them. In addition, if it is a roof leakage, you can also observe the cracks, and at the same time check whether the waterproof layer is aging. A special pear filler can be used to fill in the answer.

Hope mine can help you! <>

In life, we often encounter the situation of water leakage, among which the water leakage problem in the bathroom is the most common, because the bathroom is the place where people use the most water throughout the day. Generally, after the water leakage, it will not only affect yourself, but also likely to affect the residents downstairs, at this time, we need to check the leakage point, and then dispose of it, Xiang Kuandan to prevent trouble to yourself and others.

1.Check whether the water pipe has penetrated If the leakage of the bathroom has spread to the side search downstairs, then at this time you should first check whether all the water pipes in the bathroom are damaged and cause infiltration, if there is water infiltration, then you can directly find the leakage point, close the water source, and then use special tools such as adhesive tape to seal the leakage point, or replace the new water pipe. 2.

Check whether there is water seepage in the common wall If the water seeps downstairs, you can check whether there is a water leakage problem between the sewer pipe and the public wall of the bathroom. If it is a sewer problem, then it should be that the sewer pipe is damaged, it is very troublesome to deal with, and it may be necessary to remove the floor and reinstall the sewer pipe. 3.

Check whether the floor drain is installed in place, many times the problem of water leakage is caused by the fact that the floor drain is not installed well, and the water in the bathroom is easy to have problems when discharged, and it is easy to damage the waterproof layer of the bathroom. At this time, if the floor drain is not installed in place, it is necessary to use leakage filling materials to make the floor between the floor drain and the sewer pipe waterproof leakage repair project, so that it will not penetrate into the downstairs when draining. 4.

Find professionals to investigate and repair for a person with poor hands-on ability, the best way is to ask a professional master to investigate and solve the problem, let professionals deal with it, not only higher efficiency, but also higher efficiency and leakage, and because it is a leak downstairs, it does need to be paid attention to and dealt with quickly, so as not to cause trouble to others, after communicating with the downstairs.
