How to check and do the leakage of underground water pipes?

Leakage of underground water pipes is a very headache, because it is underground, invisible and intangible, and it is very troublesome to deal with. So what about the underground water pipe leaking? To solve the problem of water leakage in underground water pipes, we must first understand the causes of water leakage in underground water pipes, so how to check the water leakage in underground water pipes? Let's look at Bian Xiao's article. By the way, who is responsible for the leakage of underground water pipes?

First, how to check the leakage of underground water pipes?

How to check the leakage of underground water pipes? Valve plug audition method can be used to check the leakage of underground water pipes, also called ground audition method.

1. First, confirm whether the underground water pipe leaks. Take both ends of the water pipe in a rage, add some pressure with the machine for testing the pressure of the water pipe, and wait for half an hour to see if there is any obvious pressure reduction. If there is, it means water leakage. In this way, the location of water leakage can be checked, and only a section of leaking water pipe needs to be replaced again. If there is no replacement condition, you can pave another replacement and discard the original one. If the water pipe leaks, maintenance is not recommended. Due to the high pressure in the water pipe, water leakage will occur after maintenance.

2. When the leaking pipe section is confirmed by the ground listening method, the leakage point of the underground pipeline is detected on the ground by the electronic amplification leak detector, and the location is accurate. Listening and testing is a comparison of listening and testing point by point at a certain distance along the direction of leaking pipeline. When the ground pickup is close to the leakage point, the stronger the leakage sound is, it will reach above the leakage point.

Second, what should I do if the underground water pipe leaks?

What should I do if the underground water pipe leaks? There are three ways to solve the water leakage of underground water pipes, one is positive plugging, the other is negative plugging, and the third is to use wall-penetrating pipe plugging device. The details are as follows:

1, positive insertion

Frontal blocking is blocking, which is also called toilet waterproofing. Here's a detailed introduction to bathroom waterproofing.

(1) basic therapy

When the toilet is waterproof, the base should be leveled first, and the place with wall-penetrating pipe should be blocked first.

(2) Waterproofing of key parts

After that, use waterproof paint to evenly brush the weak parts that are prone to water leakage, such as the root of the wall pipe, the floor drain, the corner of yin and yang, etc.

(3) coating waterproof film

Large area waterproof coating is applied to the ground. Special parts such as through-wall pipes, corners, joints, etc. must be carefully painted, with uniform coating thickness and tight sealing, and there can be no bulging, cracking, falling off, exposed bottom, warping and lax sealing.

(4) Closed water test

After the waterproof layer of the kitchen and bathroom is dry, it is necessary to carry out a closed water test for more than 24 hours to check whether there is a wet water point on the roof downstairs. If there is no wet water point, the construction is qualified. If there is wet water point, it must be reworked.

2. Reverse blockage

If the house leaks in use, you can use the opposite side to stop the leakage.

(1) Remove the top gusset and ceiling downstairs first.

(2) Hook the groove around the root of return pipe.

(3) Use a wire brush to polish the base surface and notch removal part, clean up dust and sundries, and fully wet the base surface until the saturated surface is dry. Insert the preset quick-setting waterproof plug into the groove of the wall-penetrating pipe and fully plug it.

(4) In the process of heating the plug to enhance the strength, spray water continuously with a watering can for curing until the surface of the plug turns white.

(5) Scrape latex paint on the wall around the water leakage, restore the top surface, and buckle the plate.

3, using the wall pipe plugging device

Installing a plugging device on the pipeline can effectively prevent leakage, and there will be no leakage where there is a plugging device. The invention can be directly sleeved on the through-wall pipe for use, thus strengthening the protection of the gap between the through-wall pipe and the concrete and preventing looseness and leakage.

3. Who is responsible for the leakage of underground water pipes?

The Property Law stipulates that the property is responsible for water leakage in front of the water meter and the household is responsible for water leakage behind the water meter.

1. If the public heating pipeline leaks, it depends on who is in charge of the leaking pipeline and who is responsible for its maintenance.

2. For the after-sales problem of public heating pipelines, heating companies and property management companies should clarify their jurisdiction. Generally, it is necessary to make clear provisions in the heating contract to avoid problems and shirk each other.

3. If there is no agreement in the contract, it is generally a circulating water heating pipe network, and the jurisdiction of the heating company extends to the pipeline valves of the entrance device of the user building. From the flange behind the door, it is under the jurisdiction of the property management company.

4. If there is no property in the community and the water pipe leaks at home, the owner can only bear the maintenance cost himself, and can't charge the cost of water leakage loss.

5. If renting a house, it will be solved by the landlord. Remember to keep the payment voucher. If you encounter difficulties with the landlord when checking out, you can sue in the community court.
