How to determine whether there is a leak in the underground water pipe

The method of judging that there is a dark leak in the underground water pipe is as follows:

Method 1: Night observation method

The night observation method is the most common and simplest method, that is, in the middle of the night, when no one uses water, observe whether the tap water meter pointer rotates, if it does not stop, it means that there is indeed a leak in the pipeline, otherwise, there is no leakage in the pipeline.

Method 2: Water Balance Test Method

The water balance test is an effective method for the scientific management of water users, and it is also the basis for further urban water conservation. The difference between the sum of the water consumption of each branch and the amount of water paid should not be more than 15%, and if it is found that the difference between the sum of the water consumption of each branch and the amount of water paid is greater than 15%, it means that there is a leakage point in the pipeline.

The significance of the water balance test is that through the test, we can fully understand the status of the pipe network of the water consumption unit, the current situation of water use of each part (unit), draw a water balance map, find out the water balance relationship and the degree of reasonable water use according to the measured water quantity data, and take corresponding measures to tap the potential of water use, so as to strengthen water management and improve the reasonable water use level.

Method 3: Water Consumption Analysis

Usually, when a leak occurs in a water supply pipeline, the amount of water leaking is equivalent to a household tap being turned on 24 hours a day, and the water consumption is abnormal, soaring by more than 20% of the daily water consumption. Therefore, when the water consumption suddenly increases due to the influence of temperature changes, there is a high possibility that there is a leak in the pipeline.

Method 4: Water pressure determination method

Hydrostatic testing is one of the most common methods of leak detection. When there is a leak in the pipeline, the water pressure will be reduced when the water pressure is found to be lower than before, and it is very likely that the pipe is leaking.

Method 5:

Check whether the toilet is leaking, you can drop a few drops of ink into the toilet pool, and then carefully observe whether there is water leakage, close the main valve, after an hour, observe whether the water level of the toilet tank has dropped, if there is, it indicates that the water tank is leaking; Check the ground or walls for damp areas, if there may be leaking water pipes buried inside.

At night, when we don't use water, the pressure of the water pipe will be greater than that during the day, this is also the easiest to hear, the leak is basically to listen, listen to the nearby water pipe whether there is a sound, judge the positioning according to the sound, or directly use the leak detector, this instrument is more expensive, the cheap one is more than 7,000, but this is only an auxiliary, and professionals are also needed.

Hello, <>

I've been waiting here for a long time, the problem you pointed to before the code, the phenomenon of leakage of the main drainage pipe of the hidden pipe is seen like this, and the leakage of the underground water pipe should be checked before we first check that it is in that position, and it is late so that you know that it should be repaired**. Underground water pipe leakage inspection method: a simple approach, is to start from the introduction of water pipes, and extend the distribution inspection of each water pipe, including each faucet, interface and other parts, to see if there is water leakage, to be eliminated, and then consider whether the problem of underground water pipes, if necessary, to start excavation.

Another way is to install a single-flow valve in front of your water meter, and see if the meter is still flowing, you can determine whether there is water theft or leakage. Wishing you good health and looking forward to a thumbs up <>

Use an underground pipeline probe leak detector. The underground pipeline detection leak detector is used to apply an AC single frequency or multi-frequency current signal to the tested pipeline, so that the target pipeline is excited to generate an electromagnetic field of corresponding frequency around it, which provides useful signals for the next pipeline positioning and leak detection. Leak Detection Method:

The built-in receiving antenna is used to receive the maximum or minimum induced electromotive force tangentially or parallel to the magnetic field lines on the pipeline to determine the plane position of the pipeline. There are a variety of measurement methods for depth measurement, such as % and direct reading sounding. When there is a damage point in the measured pipeline, the ground electric field above the point will change gradually, and the electric field signal above the pipeline will be sent to the instrument for processing by the two input electrodes of the instrument through the human body of the detector or a subframe, so as to determine the location of the damage point.

Summary. Hello, the kind of water leakage point you are talking about is called a leak in the industry, that is: a leakage point hidden in the ground that cannot be seen by the eye.

There are two types of leaks, one is the leakage of the water pipes in the house, and the other is the leakage of the water pipes on the municipal streets.

If your question is the former. It is recommended that you replace the pipe directly, do not find the leakage, and then repair it. Because the method of replacing the pipeline is more economical, cheaper and hassle-free.

For the latter, the pipeline leakage on the street is the leakage of the public pipeline (the public pipeline inside the unit also belongs to this category), the public pipeline is generally large in caliber, the cost is high, and it is not suitable to take the replacement method to solve it, generally the leakage point is detected first, and then excavated and repaired.

How to find leaks in the running water of the buried pipe of tap water.

If it is a public pipeline, you only need to go to the relevant departments, and they will send someone to repair and replace it

Nowadays, water pipes are generally buried in the wall or ground during renovation. Although the overall effect of the buried method is more beautiful, the problem of water leakage will occur after a long time, and the maintenance is more troublesome. So how to detect the leakage of buried water pipes?

How to detect leakage from buried water pipes

First turn off the main valve, then turn on all the faucets and keep the water running for about half an hour, until all the water remaining in the pipe has flowed and then close. Next, turn off the water inlet switch of toilet tanks, water heaters, and other equipment with water storage functions. Finally, open the main valve and observe whether the water meter will go, if it will go, it means that the buried water pipe will leak.

What to do if the buried water pipe is leaking

1. First of all, you must determine which section of the water pipe is leaking, and then you must remove the wall or pry open the floor, so that you can find the water pipe. Pay attention to the need to be careful when dismantling to prevent damage to other pipes. If the water pipe leaks severely, the leaking part should be cut off and replaced with a new one, so that the leakage problem can be completely solved.

However, be careful to bond the new water pipes firmly and tightly.

2. Glue repair.

If there is a small leak in the pipe, it can be repaired with glue or repaired with hot melt adhesive. If the pressure in the pipe is high, this method is not suitable because the pressure of the water can easily wash away the solidified glue, which can lead to another leakage.

3. Repair welding with welding torch.

If the buried metal pipe is buried, then glue should not be used, because the glue has a poor adhesion to the metal. Since metal pipes are not easy to saw, it is not suitable to replace them with new ones, so they can only be welded. However, if the inner wall of the pipe is severely corroded, the only way to do it is to replace it with a new one.

Concealed water pipe is installed in the wall or under the ground water pipe, now the owner in order to make the home decoration appear more beautiful, more tidy, usually choose this wiring method, but this wiring method once there is a water leakage, must be dealt with immediately, and it is very troublesome. So, how to judge the location of the leakage of the concealed water pipe? How to deal with leaking water pipes in the wall?

Let's take a brief look at it together.

1. How to judge the location of the leakage of the concealed water pipe.

The location of the leakage of the concealed water pipe can be judged by a professional water leakage detector, because the instrument is mainly through the noise of the leakage, to determine the location of the leakage, so it is more accurate, or it can also be checked through the water pipe pressure test, one by one to check the location of the leakage of the concealed water pipe, if the pressure value drops seriously, it means that there is a water leakage in the section, otherwise, that is, there is no water leakage.

2. How to deal with the leakage of the water pipe in the wall.

1. Finding the location of the leakage is the key, because the concealed water pipe is installed inside the wall, and the surface may be paved with tiles, and the waterproof performance is good, so the leakage will spread to the periphery, and sometimes the leakage part is opened, and it is found that there is no leakage, which is very troublesome, so before the maintenance and treatment, it is best to find the location of the leakage with the help of professional instruments, and then deal with it according to the actual situation.

2. After confirming the leakage point, you need to chisel the wall or ground first, pay attention to the finished furniture in the construction process, be sure to protect the finished furniture, including tables, chairs, cabinets, etc., and then confirm the leakage position of the pipeline again, and clean it clean, so as not to affect the post-processing, and finally repair it according to the actual leakage situation.

Summary: The above about how to judge the location of the leakage of the concealed water pipe, and how to deal with the leakage of the water pipe in the wall with the wheel defeat and the water pipe leakage in the wall are introduced here, I hope it will help you.
