How to detect pipeline leakage, how to detect pipeline leakage

Household water pipes, geothermal pipes leakage detection method:

1.First of all, choose the pressure detection, close the tap water valve in the household, link the tap water and cold water with a soft connection, and close all the angle valves to prevent the angle valve from being non-zero sensitive, resulting in inaccurate pressure detection results.

2.After the link is good, hit the water pressure to 8 kg of water pressure, to see if the pressure is dropped, such as the pressure drop speed is fast (2-10 minutes pressure gauge to zero), such a speed can be sure that there is a problem of water leakage in the water pipeline, if 1-2 kg of pressure is dropped in 10 minutes, you can press to 8 kg pressure again, continue to observe, if you do not lose pressure, or fall to 6-7 kg pressure, hold the pressure for 30 minutes and do not continue to drop pressure, can be regarded as normal. There is no leakage in the pipeline.

3. If there is no pressure relief phenomenon in the tap water cold water pipe, you can choose to test the pressure of the hot water pipe, and the operation is as above.

4.If there is no pressure relief phenomenon in the tap water cooling water pipe and hot water pipe, it is necessary to consider geothermal pressure, and geothermal pressure is best to be detected in a group, so that the results will be very accurate.

5.If there is no pressure relief phenomenon in the above, you can consider whether it is a sewer pipe, a waterproof bathroom, or a water leak in the neighbor's house next door.

The more troublesome thing we usually encounter is the leakage of the water pipe, which will bring a lot of troubles to our lives, many reasons will lead to the occurrence of water pipe interface leakage, or it may be a problem with the pipeline, so how to effectively operate the pipeline leakage detection? Today, Wuhu Chengfei pipeline inspection will analyze with you, and the specific steps are as follows!

1. Open all the water outlets in the home, and then seal each water outlet with a sealed material, and close the water valve switch that controls the main switch, which must be closed tightly, otherwise the data obtained will not be accurate. If the pressure test is not exceeded within 30min, and there is no leakage at each connection, then the water pipe at home is qualified.

2. If the water pipe test confirms that the water pipe is leaking, then observe where the water seeps out, and then confirm the direction of water seepage, check them one by one, and destroy the ground and wall again, and even affect the beauty of the house.

3. If the water pipe test is qualified and there is no water leakage, but there are water marks in the floor cracks at home, this is because when decorating the floor tiles, the decoration workers have infiltrated a large amount of waste water into the cement mortar under the floor tiles, and when there is too much water, it will cause the water to penetrate into the relatively low place, which will lead to the water seeping out from the floor tile joints.

Pipes can be seen in every family, its installation is an important project in the decoration of the house, in the process of use, some families will have water leakage. So, how to detect a leak in a pipe? What are the causes of leaking pipes? Let's take you to find out.

Pipeline leakage can be detected by listening to sound and vibrating, that is, using a certain sound-transmitting tool to listen to the sound of running water in the pipeline, so as to judge whether there is water leakage. Or use infrared thermal imaging to detect leakage in pipelines, which uses photoelectric technology to determine whether there is water leakage in pipelines.

Causes of pipe leakage.

1. Many pipeline leaks are caused by cracks in the sink bolt, and some of these cracks are caused by aging, and some are only caused by improper use, but most of them are caused by damage to the sealing gasket in the gland. In this case, we just need to take out the gasket and replace it with a new one.

2. When there is a problem with the outlet of the sink, the pipe will also leak, which may be caused by the damage to the shaft gasket inside. For water leakage caused by this situation, simply remove the sink gland bolt with pliers, then take out the shaft gasket and replace it with a new one.

3. There will be water leakage in the pipeline, which is mainly caused by the loosening of the lease Zhaojing sink when it is connected to the joint. Because in the process of use, the sink will be loose due to the faucet part of the cap nut phenomenon, and begin to leak, for this need to replace a new cap nut, and then install it, and tighten it, or you can change a U-shaped tight gasket, can solve the pipe leakage.

Article summary: The above is all about how to detect pipeline leakage and what are the causes of pipeline leakage, I hope it will be helpful to you. If you want to know more, please continue to pay attention to Qeeka Home.

The method of detecting water pipe leakage is as follows:

1. First of all, you can look at the surface of the water pipe, see if the surface of the water pipe is wet, this can take the paper to rub the water pipe, see if the paper is wet, if it is wet, it proves that the water pipe is leaking.

2. You can also see whether the wall near the water pipe is moldy, if it is moldy, it proves that there is water leakage, because the wall will be moldy when it touches the water, and you can also check whether the water pipe is leaking.

3. In addition, you can put some saliva in the leakage of the water pipe to see if there are bubbles coming out near the water pipe, if there is, it proves that the water pipe is leaking, because if the water pipe is leaking, it will bubble when it touches the saliva.

4. There is also a phenomenon that can be carefully observed whether the water pipe is dripping, drop by drop, this can be observed, if there is a drip, it can also prove whether the water pipe is leaking.

The proper way to use the drain

1. Do not pour decoration materials, such as cement slurry, white paste, and plastic floating objects and other sundries into the kitchen or bathroom pipes.

Residents of the building should regularly use fire, alkali or hot water to flush the sewer pipes frequently.

3. Do not pour edible oils and vegetable residues into the sewer.

4. Edible oil and vegetable residue are one of the reasons for sewer blockage and hindering water treatment.

5. Please use newspapers to blot up the old oil and leftover oil, and then dispose of it as combustible garbage.

Water pipes are usually installed in the wall, and if there is a leakage problem, it will not only affect the water consumption, but also may cause the wall to become moldy and peeling. So how do you detect a leak in a water pipe? How much does it cost to detect a water leak? Let's learn about it right away, I hope it will be helpful to you.

1. How to detect water pipe leakage.

The best way to determine if a water pipe is leaking is to do a pressure test. First close the main valve of the pipeline, and then use a manual press machine to press the water pipe, when the pressure is 8 10 kg, stand for half an hour, if the pressure can be kept without dropping, it proves that the water pipe does not leak. If a water leak is detected, the leakage will be obvious, and the pressure will be difficult to maintain for a long time, and the pressure gauge will generally drop pressure in a short time.

At this time, let the pipeline stop running, wait for the surface of the pipe to cool down, and then close the valves on the water separator after the hot water is pressurized, we can observe the pressure gauge to determine whether the pressure gauge has changed. Then open the valves of each circuit respectively to observe which circuit has a pressure drop phenomenon, if there is a circuit with obvious pressure reduction, it is a leakage circuit. After determining the leaking circuit, start digging the wall and repair the leaking pipe, and it is recommended that the leaking pipe be replaced.

At the same time, it is also necessary to waterproof the pipe and the pipe groove in the wall, so as to prevent the pipeline from aging and leaking again in the future.

Second, how much does it cost to detect water pipe leakage?

Generally, it is a special pressure pump water pressure test, and then the pressure test record is made, and the labor cost is about 150-250 yuan. An additional 80 yuan will be charged for the separate trial, and the specific ** will be charged separately according to the on-site treatment method.

Conclusion: Generally speaking, the phenomenon of high-quality water pipe leakage is relatively rare in daily life, and it is generally caused by the cross construction damage in the decoration process. Therefore, it is recommended to choose a better pipe and pipe material in the purchase, and ask a professional construction team to deal with it.

Otherwise, it will be more difficult to transform and repair in the later stage, and it will also cause a lot of additional losses.

The water supply pipe leakage detection methods include observing water consumption, observing the signs of walls, floors, ceilings, etc., observing the movement of water meters, observing the situation of water pipes, and testing with pressure pumps.

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 indicates a leak in 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 branching 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.

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 is a hidden pipe, you need to check the ceiling of the downstairs neighbor to see if there are any water stains and skin 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.

Water pipe leakage can be said to be a problem, not only will cause your home to be wet all the time, but also affect daily water use, waste of water resources, so the water pipe leakage should be found out in time to find out the cause, and repair. So how to detect water pipe leakage, and how to maintain water pipes, do you know? Now let's take a look.

1. How to detect water pipe leakage.

Through the pressure test, it is judged whether the water pipe is leaking. At this time, it is necessary to close the main valve of the water pipe, install a manual press, control the pressure at about 10 kg, and stand still for a period of time, if the pressure is unchanged, it means that there is no water leakage, on the contrary, the pressure falls in a short time, indicating that the water pipe is leaking.

Second, how to maintain the water pipe.

1. If there is a problem with the water pipe, it will leak, and the amount of water leakage is greatly related to the amount of indoor water pressure. Therefore, no matter if the water pipe bursts, causing water to gush out or drip out, you need to close your water valve immediately, and contact the relevant maintenance personnel immediately after the water does not flow, so as not to affect future use.

2. After the water pipe is broken, you can wrap the tape dedicated to repairing the water pipe, which can prevent the continuation of water leakage and make tap water normally. Moreover, some families often use glass fiber glue or resin adhesive for repair, which can also repair the effect of water pipe cracks.

3. If the daily water pipe burst is serious, you should first wrap the damaged water pipe with a towel at home to avoid water splashing everywhere, and then contact the relevant personnel to repair it. If the water pipe breaks over time, then there is no need to repair it, and it is recommended to buy a new water pipe to replace it to avoid frequent trouble.

About how to detect water pipe leakage and how to maintain water pipes, I will introduce it here, do you understand? Leaky water pipes will have a greater impact on an individual's home life, so once a water leak occurs, no matter how big or small, it needs to be repaired.

In life, we will encounter such and such troubles, in which the water pipe is an indispensable part of every home life, although the pipe is a hidden part, but the pipe leakage often occurs. Since it is a hidden part, how can the water detect a leak in the pipe. There are many reasons that can lead to the occurrence of water leakage in the water pipe interface.

Therefore, there are some things to understand about the causes of pipeline leakage.

Since it is a hidden part, how can the water detect a leak in the pipe.

There are many reasons that can lead to the occurrence of water leakage in the water pipe interface. Therefore, we need to do some understanding of the causes of pipe leakage.

How to detect a leak in a pipe?

1. The first thing to do is to close the main sluice. Then use a hose to fix it at both ends of the hot and cold water pipes.

2. After everything is ready, it is ready to be pressurized for testing.

3. At the same time, fix one end of the instrument on another water pipe in the same space.

4. When the master is using the instrument, he needs to screw every interface so as not to cause air leakage, so that the measured water pressure will be accurate.

5. Gradually increase the water pressure and test the pressure bearing capacity of the water pipe to see if there is leakage of the water pipe.

6. Check the water pipes everywhere to see if there is water seepage and leakage.

7. The inspector beats the water pressure high, according to popular saying, the water pressure at this time is 8 catties.

8. The inspector touches the water pipe with his hand to see if there is any dripping. The whole process of measuring the water pressure needs 30, if there is no water seepage and leakage, it means that there is no problem with the pipeline.

Causes of pipe leakage.

1. Water leakage in the gap under the sink bolt, solution: The leakage in the gap under the sink bolt is caused by the leakage of the faucet caused by the wear of the triangular gasket in the gland. At this time, loosen the screws of the kitchen faucet and remove the tie head, then remove the gland after loosening it, and then take out the triangular sealing gasket on the inside of the gland and replace it with a new one.

2. The sink outlet is leaking, the solution: use pliers to loosen the gland and remove it, take out the axial gasket with a clip, and replace it with a new axial gasket. If there is a leak at the sink outlet, it is usually the shaft gasket in the sink that is worn out and needs to be replaced with a new shaft pad.

3. Leakage at the joint of the sink pipe, solution: The leakage at the joint of the sink pipe may be due to the loosening of the cap nut of the faucet, and it can be solved by re-tightening the cap nut or replacing a new U-shaped gasket.

Water pipe interface leakage is very common in our daily life, how to detect pipeline leakage is the key, there are many reasons for pipeline leakage, we can detect through the above methods, find the problem as soon as possible to solve the problem as soon as possible. I hope what is written above can help you and serve as a reference suggestion for everyone.
