Who knows how to detect where water leaks are? Which netizen knows?

1. Collect pipeline data.

Collect the drawings and water consumption data of the pipeline that need to be tested, and arrange technicians who are familiar with the location of the pipeline to point out the relevant information of the pipeline on site.

2. Environmental investigation of regional pipe network.

The purpose of the environmental investigation of the pipeline network is to fully understand the on-site situation and prepare for the construction arrangement and method selection of the next water leakage detection work, including the environmental investigation of the pipeline network, the investigation of ancillary equipment, the investigation of water use and the investigation of drainage.

1) Pipe network environmental investigation: water supply pressure; Pipe Material; Pipeline pavement.

2) Ancillary equipment investigation: wells, meters, valves, and bolts in the investigation area, and preliminary investigation of water leakage of the above appendages.

3) Investigation of drainage conditions: Conduct a detailed investigation of all underground structures involved in the vicinity of the pipe network, such as drainage pipes and cables.

3. Detailed investigation of water leakage.

In the work area, 100% direct listening is carried out on fire hydrants, valves, water meters and open pipes in the area during the day to listen to the sound waves transmitted from the leakage point to the pipeline structure, and the water leakage anomaly is found. After the anomaly is found, a detailed record is made, including the field number, location, nature of the anomaly, abnormal condition and explanation, etc.

4. Audio and audio detection.

Above the pipeline in the survey area, use a water leakage detector to follow the "S" pattern along the pipeline at intervals.

The operation is carried out during a period when the water consumption is relatively stable and the surrounding environment is relatively quiet.

Investigate leaks in pipes buried under the road surface and mark the potential for leakage on the ground.

a.Perform a "m" profile detection at the anomaly.

b.The pavement hearing rate is 100%, and the sound anomaly detection rate is 100%.

c.Make a detailed record of the anomaly and the surrounding environment.

d.Pavement listening should also assist in valve bolt listening and environmental investigation.

5. Confirm the leakage point and locate the leakage point.

For the water leakage anomalies or areas that have been discovered, organize personnel with high technical level and rich experience to judge the abnormalities, eliminate abnormal interference, and confirm whether it is an abnormal water leakage. If the water leakage is abnormal, the leakage point will be accurately located.

Accurately locating water leaks is a comprehensive and complex task. It is necessary to comprehensively use a variety of methods such as ground sound intensity and audio detection, pipeline sound intensity and pipeline close sound intensity audio detection, and comprehensively analyze the results of valve bolt detection, road surface detection, related detection and other detection methods, and finally confirm the accurate location of the water leakage point.

Once the leakage detection controller detects the liquid, the leakage positioning controller will generate an audible and visual alarm, and the digital tube will display the leakage location, and trigger the relay to produce a voltage-free contact closure; The sensor monitors the water leakage signal in real time, and when the leakage occurs, the system receives the water leakage signal for alarm and locates the leakage location to automatically close the corresponding water valve. When there is a fault, the corresponding display screen will automatically jump out, display the fault point, greatly reduce the loss and prevent the accident from expanding, the water leakage detection controller has the advantages of good real-time performance, low cost, safe and reliable operation, etc., you can go to learn more about it, I hope my help to you.

Here's how to detect a water leak:

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.

Prevent water leakage in the home

If we want to avoid water leakage at home, we need to choose high-quality waterproof coatings, water pipe fittings, and waterway renovation and waterproof construction should be strictly installed and used for construction and acceptance.

For example, after the water pipe is laid, we should do the pressure test bridge front, and after the construction of the waterproof layer is completed, we should do the water storage test for acceptance, and we can not destroy the waterproof layer and water pipes at home in the later decoration process, and we should turn off the faucet at home when we go out, and if you go out for a long time, you can turn off the water valve at home and so on.

1.Observe the water meter.

The first step in detecting a water leak is to look at the water meter. Turn off all faucets to make sure there are no water appliances running, and then watch for movement on the meter's pointer, if the pointer keeps turning, it means there is a leak.

2.Inspect the pipe connections.

If the meter pointer keeps turning but no water stains are found, the leak may be at the pipe connection. The pipe connection is the most common place for water leakage, and you can feel the pipe connection with your hand for moisture or water stains. For water leaks in pipe connections, it is best to ask a professional to fix them.

3.Use a paper towel to check the faucet.

The faucet is the place where water is most frequently used in the home, so it is also a high area for water leakage. The usual way is to check the faucet for leaks with the help of a paper towel. Place the paper towel under the faucet and observe if any water droplets fall onto the paper towel.

4.Listen to the sound check.

In addition to observing with the naked eye, listening to sound is also one of the ways to detect water leaks. Calm down and listen carefully to your home for "tick-tock" sounds, usually from a water pipe or faucet.

5.Check with a stain.

Dyes can be used to detect the most insidious water leaks. Put the dye into the water tank or water pipe, and observe whether there are any stained water stains at the end of the water tank or water pipe.

6.Seal the pipes.

If you can determine that there is a water leak, you can try wrapping it and wrapping waterproof tape around the leak to seal it. This method can prevent further spread of water leakage and cause more waste and loss before finding the leak, but it is not a long-term solution, such as finding water stains, odors, etc., to deal with it in time to avoid more losses.

7.Regular check-ups.

The best way to prevent it is to check it regularly and not wait for the leak to become a widespread problem. You can set a certain burning day of the god shirt every month as the day to check for water leakage to avoid the problem of missing inspections.

8.Summary. All in all, detecting a water leak is a small thing, but it's a very important one.

Due to a small water stain, it can cause a lot of damage to the family in the long run. Therefore, we should actively detect water leakage problems so as to avoid the harm caused by water leaks to the home.

The methods of detecting water leakage include observing water consumption, observing signs such as walls, floors, ceilings, etc., observing the movement of water meters, observing water pipes, testing with pressure pumps, observing key areas, and so on.

1. Observe the water consumption.

Looking at this month's water bill, if there is a sudden surge in water bills, excluding special water use situations, it is likely to indicate a water pipe leakage, which is the easiest and most direct way to detect water leakage.

2. Observe the signs of walls, floors, ceilings, etc.

If there is an abnormality in the walls of the home, such as the wall paint and wallpaper are black and bulging, it may be a leak in the pipes in the wall; If the wooden floor is bulging and the color around the tile gap becomes darker, it is a warning of leakage from the underground water pipe; If there are water stains oozing out of the ceiling, and the wall skin is cracked and falling, it indicates that the top water pipe is leaking.

3. Observe the movement of the water meter.

Close the valves in the house, open the main valve, if the water meter is still moving, it will indicate a water leak. Of course, if you don't move, it doesn't mean that there is no water leakage 100%, if it is leakage, the rotation of the water meter can not be judged with the naked eye, and you need to find a professional testing master to help judge it.

4. Observe the condition of the water pipe.

Observe the exposed water pipes at home, wipe the water pipes clean with a clean cloth, put a clean cotton cloth on the ground where the water pipes are connected, if the cotton cloth becomes wet and wet after a period of time, it indicates that the water pipe is leaking, this method is suitable for vertical open pipes. If it's a hidden pipe, you'll need to look at the downstairs neighbor's ceiling to see if there is any water stain seeping.

5. Use the pressure pump for testing.

Buy a set of pressure pumps, close the main valve and each faucet, remove one of the valves and press inside, if the pressure drops, it will indicate that the water pipe is leaking. This method is more professional, there may be problems if you don't pay attention to the operation, try not to operate yourself without relevant experience, it is best to find a professional leak detection team.

6. Observe key areas.

If the house is older and suspected of leakage, you can focus on checking the faucet, drain pipe, shower head, etc.

The slip methods for water leakage detection include environmental investigation method, pressure test comparison method, and residual chlorine detection method.

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 with the mountain 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 collected water samples can be detected and whether the leakage is caused by visual color comparison can be determined.

Ways to prevent water leakage:

The self-leveling layer is 30 cm higher towards the wall. Showers and walls with waterproof requirements have a height of 180 cm. The waterproof coating should be coated with no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

In the construction and transformation of water pipes, it is necessary to prevent sewer blockage, and to close and protect the sewer and floor drain before construction to prevent cement, sand and other sundries from entering. Once the cement and mortar block the passage, it is extremely difficult to clean up, which will bring great trouble in the spring.

After the construction of the kitchen, bathroom and waterproof layer is completed, the closed water test must be done, and the company and the owner can only do the surface layer after the test results are qualified. If you don't do the closed water test or the test is not qualified, you will make a waterproof layer, and when the water leaks in the future, you can only remove all the waterproof layers and start again. <>

Generally, there are two reasons for water leakage in the bathroom, one is water seepage on the ground, and the other is water seepage caused by broken water pipes.

1. Judgment of pipeline water seepage: pipeline leakage refers to the leakage caused by the damage of the upper and lower water pipes, floor drains and toilet interfaces

1) Leakage of water pipes.

The manifestation of this situation is that the leakage is continuous and uninterrupted, and sometimes the leakage volume is constantly increasing, such as closing the main valve of the water pipe, and the leakage will be reduced immediately.

2) Leakage of sewer pipes.

Observe the amount of leakage, open all faucets, toilets and drain water multiple times, if the leakage increases, it means that the pipe is damaged and leaking.

2. Toilet water pipe leakage test method.

1) Test whether the water inlet pipe is leaking: write down the data of the water meter, let the upstairs not use any water at this time, and check it after two or three hours; If the inlet pipe is leaking, it will definitely be reflected on the water meter.

2) Test whether the drain pipe is leaking: turn off the sluice, drain all the places where there may be water, find a water pipe to flush the floor drain, and insist on a little longer to see if there will be water leakage downstairs.

3) Waterproof layer leakage test: close all the sluices, drain all the water in the water pipes, and do a closed water test for 24-48 hours to see if there will be water leakage downstairs.

Hello, I am aware of the high water long leak.

Your estimation direction is right, such a leakage is generally caused by waterproofing or leakage of sewer pipe joints, and the possibility of water leakage is not very likely, because the water leakage will be reflected quickly, and it will not wait until two days to have water seepage.

You have no other way, just redo the waterproofing, even the sewer joints are redone, once and for all.

It's hard to find the leak accurately, and even if you do, you'll still need to break the waterproofing layer.

Hope mine is helpful to you.

You can only plane the floor to find the leakage, and it is difficult to find the geothermal heat, disconnect it at the leakage point after finding it, connect it with a joint, and continue to use the geothermal system if you press it again, but remember not to carry out projectile geothermal cleaning!

Specific steps of geothermal pressure detection:

a. With each component and water collector as a unit, fill the floor heating system with water pressure pump, and at the same time, slowly increase the pressure of the gas in the system pipeline to or twice the working pressure of the system;

b. Observe and inspect the floor heating pipeline at any time during the pressurization process. Floor heating pipes with points. Water collector attachment points. Manifolds.

and its connectors, etc., whether there is leakage;

c. Check whether there is any leakage point after one hour of voltage stabilization;

d. After confirming that there is no leakage, the pressure will be raised again, and the pressure will be observed for 15 minutes, and the pressure drop will be qualified.
