Can the underground water pipe of the house be leaked, and the traces of soil seepage can be detecte

Can the underground water pipe of the house be leaked, and the traces of soil seepage can be detected two years after the water is turned off? You can use the valve bolt listening method, the ground listening method, and the following is a specific introduction to the method:

1. First of all, we must confirm whether the water pipe is really leaking, plug the two ends, find a machine to test the pressure of the water pipe, try to add some presses into it, and then wait for half an hour to see if there is a significant decrease in pressure, if there is a real water leakage. Use this method to confirm which section of the water pipe is leaking, and if there is a condition after confirmation, replace the leaking section of the water pipe, and if there is no condition, you can lay another one to replace it, and the original one will be discarded. It is not recommended to do repair, because the pressure in the water pipe is high, and the repair will not last long, and it will leak;

2. Ground listening method.

When the leaking pipe section is determined by the pre-positioning method, the leakage point of the underground pipeline is listened to on the ground with an electronic amplification leak detector and accurately located. When the ground pickup is close to the leakage point, the stronger the water leakage sound, the maximum at the top of the leakage point.

Extended information: The method of water pipe leakage buried in the ground has mutually beneficial pipeline leakage detection and telling that the leakage point can be found out by audio leak detection method for maintenance, and the sound and audio leak detection method is divided into two types: valve bolt hearing and ground listening, the former is used to find the clues and scope of water leakage, referred to as leakage point pre-positioning.

Generally speaking, the distance between metal pipes is 1 2 meters, the distance between non-metal pipes is meters, the distance between cement pavements is 1 2 meters, and the spacing of dirt pavements is meters.

Of course I was able to check it out. The ground is not leaking. It's not the same as a leaky floor.

If there is water seepage, there will be a depression in that ground. Impermeable the no. And that underground pipe definitely has.

The presence of leaky rust. No leakage, definitely not. So you just have to cut the ground open and you can see it.

Traces of water leakage. Because one by one. To leak, there must first be a leak.

As long as there are leaks. You can find traces of the water that penetrated in the first place.

General leakage point bai

are all judged in the joint or bending du, and then combined with the water dripping part.

zhi.There are two situations of water leakage, one is that the special waterproof layer is not done well, which leads to water leakage, and the other is that the pipeline is broken, if there is no water leakage, it should be the pipeline leakage, only the wall can be beaten, the pipeline is repaired, and then the pit is filled, and then the waterproof is redone.

Hello, you can notify the water company, they have professional testing equipment that can detect water leakage in buried water pipes.

Answer: If you find that there are water traces on the floor or wall of your home, how to check if the water pipes at home are leaking? Or just finished renovating and want to see if there is a water leak, how to check it? Here is a very simple and easy-to-use method! Very practical!

Start by turning off all the faucets in your home!

Then turn off the main switch of the main valve for tap water in your home.

Then find the water meter at home.

Then keep an eye on the black gear pointer on the water meter. Turn on the main switch, and observe whether the black gear rotates at the moment when the main switch is turned on. If it does not turn, it means that there is no water leakage and water seepage, and if it is turned, it means that there is water leakage and water seepage.

The main water valve at home is closed, and the water is still leaking downstairs, it is very likely that the water pipe is broken, otherwise it is impossible to close the main water valve and leak, check the section of water pipe in front of the main water valve.

Nowadays, in life, we often encounter the phenomenon of water pipe leakage, even if the water pipe valve is closed, there will still be a dripping situation, which makes many friends feel very distressed, and if it goes on like this, it is also a waste of water source, so it is necessary to solve it in time, so why can't the water stop when the water pipe valve is closed? What should I do if the water pipe is leaking? Let's take a look at the relevant knowledge.

Generally speaking, if the water pipe has been used for a long time, it will leak due to aging and damage. If it is found that the sewer joint is leaking after inspection, you can cut off the end of the bad water pipe first, and then install the new water pipe according to the alignment;

1. The water pipe joint is loose. Water leaks sometimes occur due to loose water joints, but this is relatively easy to solve. Just find the loose water pipe fitting and find the tool to tighten it tightly;

2. The water pipe joint is frozen and cracked. If the water pipe is often exposed to direct sunlight, especially in winter, the water pipe is easy to freeze and crack, so there will be water leakage.

Why can't the water stop when the water pipe valve is closed What should I do if the water pipe seeps.

First of all, you have to prepare materials, buy 2 4 pipe pinches (pipe hoops) If you are 4 pipes, then you have to buy 6 points or one inch pipe pinch, and then buy a roll of high-voltage insulating tape (these two things are generally available in building materials stores) It is best to go to the old man who repairs the bicycle to buy a bicycle inner tube, the materials are complete;

First use insulating tape to spirally wrap the leakage section, preferably more than two layers (note that the insulating tape must remove the separator) and then wrap 1 or 2 layers of bicycle inner tubes, and then tighten the pipe pinch. Do it yourself, it's very simple, and replace the PPR tube when it's convenient.

If the water pipe valve is closed, there will still be water leakage, it is recommended that you solve it in a timely manner, and at the same time to learn more about the relevant knowledge, do a good job of treatment, the above is about the water pipe valve closed, why the water can not stop and the water pipe seepage What to do, you can choose the appropriate method to solve it in combination with the actual situation.

The main valve is closed, not the water inlet pipe, the upstairs without water is certainly not the upstairs to your house sewer pipe leakage, so your home should be the toilet that the main sewer pipe around the leakage, upstairs if you can go in, see if the contact between the main sewer pipe and the roof of his house is wet, if wet go to the upstairs to check upstairs, if not, first, there is a leak between the main sewer pipe upstairs to your home, two, do not rule out water seepage due to rain.

It must be a plumbing problem.

Be sure to perform a pressurization test after installation. The pressurization test is generally carried out under the condition of double water pressure, and there should be no water leakage in the test.

A simple test method without a pressurized strip capacity, but not entirely feasible.

1) Close the main valve of the water pipe. (i.e. the water pipe switch in front of the water meter) 2) Turn on the faucet in the room for 20 minutes, make sure there is no more water dripping and turn off all the faucets.

3) Turn off the water inlet switch of equipment with water storage function, such as toilet tanks and washing machines.

4) Open the main valve of the water pipe.

5) Check whether the water meter is moving 20 minutes after opening the main valve, including slow walking. If there is movement, it is a water leak. If you don't move around, you'll probably be fine.

If there is a problem with the water meter or if the water pipe is slightly percolated, it may be difficult to determine. Therefore, it is recommended that the water pressure test experiment must be carried out after the construction, generally 8 kg, and the time is 20-30 minutes. (It's best to see it in person.)

Water pipes go underground:

1) The surface of the wall paint is moldy and blistered.

2) Blackening of baseboards or wooden floors and fine bubbles on the surface.

Water pipe goes to the top:

1) Dampness or water dripping on the canopy.

2) There is dampness or water seepage out of the wall tiles of the pipe.
