How to find a leak in a dark pipe

If the dark water pipe at home is leaking, you can use the water pipe color box, concealed installation, and look at the interface to view, as follows:

1. Look at the water pipe color box

If the water pipe color box at home is surface-mounted, observe the leakage of the pipe, and the leakage point is still relatively easy to find. You only need to wipe all the water pipes at home with a dry cloth to see where there are water droplets or water flowing out, which is a leakage.

However, if the water pipe is vertical, it may be necessary to observe more, because the water will flow from high to low, so we can find the leakage point by carefully following the water flow traces upward. There may also be a leak in the middle of the flowing water, so it is necessary to make sure repeatedly.

2. Concealed installation

Observe where there is a watermarkIf the water pipes in your home are concealed, you can observe the ceiling, walls and ceiling of your neighbor downstairs. The place corresponding to the water stain and watermark is basically the location of the water leak. But the pipe, which is also vertically followed by the wall, is a little more complicated to determine.

The approach in the previous article could be followed.

3. Look at the interface

The joints between the connections of water pipe fittings are often the most prone to water leakage. Generally, faucets, water pipe joints or installation joints are places that are prone to water leakage. Therefore, when installing water pipes, you must find a professional hydraulic master to avoid problems in water pipe joints.

4. Refer to the waterway layout drawing

It is important to keep the layout of the water pipes for the water pipes, especially if the water pipes are concealed. When a water pipe is leaking, it will be much more convenient to have a waterway map. The waterway diagram can be used to understand the location of each joint, where the water pipes turn, divert, and meet, and the direction of the water pipes.

On the basis of observing the leakage and water stains of the water pipe, the leakage point can also be quickly found by referring to the water pipe layout drawing.

5. Thin-walled stainless steel water pipe construction is adopted

Thin-walled stainless steel water pipe fittings double clamping fittings, one-time forming, connection sealing, smooth and clean pipe, reducing water resistance and reducing the erosion and wear of water pipes by water flow, effectively avoiding the problem of leakage of home improvement water pipes.

How to investigate the leakage of hidden pipes at home: 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 that there is no water dripping again, and then turn off all the faucets.

3. Turn off the water inlet switch of equipment with water storage function, such as toilet tank and washing machine. 4. Open the main valve of the water pipe. 5. Check the water 20 minutes after opening the main valve.

The waterway is a more important position for decorating the house, and when decorating the waterway, the quality of the material must be guaranteed, otherwise it will lead to water pipe leakage. What should I do if my water pipe is leaking? If the user can't find the problem of water leakage, you can find the master who decorated the house before to see if there is a decoration waterway design drawing, and then find the location of the leakage of the dark water pipe.

1. How to find the leakage point of the dark water pipe.

1. Close the main valve of the water pipe.

If the hidden water pipe is leaking, you can close the main valve of the water pipe first, and then find the leakage point of the hidden water pipe according to the leaking part.

2. Make sure the faucet is not leaking.

The user can turn on all the faucets and turn them on for about 20 minutes, making sure the faucets are not leaking and closing.

3. Turn off the water storage function of the toilet and washing machine.

Make sure there is no water leakage problem by turning off the water inlet switch of equipment with a water storage function, such as toilet tanks and washing machines.

4. Check the water meter.

Check the meter for movement, including slow movement, 20 minutes after opening the main valve. If there is movement, it is a water leak.

6. Listen. Use an iron rod to follow the line of the water pipe, one end against the wall or the ground, and the other end on the ear, listen carefully, and generally you can find the leakage.

2. What should I do if the water pipe is leaking?

1. Water pipe joint leakage.

Water pipe leakage may be the water pipe joint is not connected, the user can disconnect the water source, unscrew the interface, if it is not tightened, then you can re-add some raw meal to re-tighten, if it is aging or is glue or welding joint leakage, it is best to replace it with a new one, if your own tools and technology are limited, you can find professional maintenance personnel to repair.

2. Leakage of sewer pipes.

If the PVC sewer pipe is leaking, the user can buy *** PVC sewer pipe and connect it, and then use PVC glue to apply it directly to the inside of both ends and the outside of the two sewer pipes. You can also buy waterproof tape to repair the sewer pipe, first entangle the leaking pipe, and then wipe it with mortar waterproofing agent and cement.

First of all, turn off the main switch of the water pipe, turn on the faucet in the room until the faucet is empty, and turn off the water inlet switch of the toilet tank and washing machine and other equipment with water storage function. Turn on the main switch of the water pipe, 20 minutes after opening to see if the water meter is moving, including slow walking, if there is walking, it is leaking, if there is no movement, it may be fine.

The installation of water pipes has open installation and concealed installation, if there is a water leakage, it is simple to find out the leakage point after all, and it is difficult to conceal it, and some have to knock off the wall tiles. Check for water leakage in the water pipe, it may be a leak at the place of your wall outlet, that is, install a figure-eight valve or a soft-connected water-saving faucet on the wall, remove the decorative cover, and wipe it with toilet paper to see. Because the leakage water flow is small, and in the interior of the decorative cover, it is generally unthinkable that the place where the wall tiles and the water outlet are empty, and the cement is not real, so there will be problems, and the repair method is to remove it, re-tie the raw tape, and tighten it.

If the above problems cannot be solved, that is, there is a leak in the hot melt interface of the PPR pipeline, then remove the wall and judge by looking at the position of the highest point of water leakage.

The kind of water leakage 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.

Leaks are divided into two categories according to ownership, one is the leakage of the water pipes of their own homes, and the other is the leakage of the water pipes on the municipal streets.

Your question falls into the former. It is recommended that you take the method of replacing 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.

When carrying out water and electricity arrangement, some families will choose to bury a part of the water pipe in the wall in order to install it more beautifully, these are the so-called dark water pipes, once the dark water pipe leaks, it is difficult to find the leakage point, so how to find the leakage point of the dark water pipe? Let's take a look with me.

How to find a leak in a dark pipe

1. First of all, you should determine whether the dark water pipe is really leaking. Close the main valve of the water pipe first, and then open all the faucets in the room for running water, about 20 minutes of running water, and then turn off all the faucets after there is no water in the water pipe.

2. Then turn off the water inlet switch of the toilet tank and washing machine and other equipment with water storage function. Open the main valve again, and after about 20 minutes, check if the meter is moving, even if it is slow. If the meter is moving, it means that the hidden water pipe is leaking.

3. The next step is to find the leakage point of the dark water pipe. You can use an iron rod to follow the line of the water pipe, one end against the wall or the ground, the other end is attached to your ear, listen carefully to whether there is the sound of running water, this method can generally find the leakage point.

4. You can also directly check the leakage point of the dark water pipe by chiseling the wet area of the wall. If the hidden water pipe is really leaking, then the wall must be chiseled open before the repair work can be carried out.

5. If the dark water pipe leaks, you can directly replace the dark water pipe for repair, or you can use the special tape for repairing the water pipe for temporary repair.

6. If you use a special adhesive tape to repair the water pipe to do temporary repair, then you should close the main valve of the water pipe first, wait until the water source is cut off, and then open the faucet to the appropriate position, so that you can drain most of the pressure in the water pipe, and then you can use the special tape to wrap the leakage position of the dark water pipe. It is also possible to use a ring resin adhesive to seal the leakage of the dark water pipe.

The above is a detailed introduction on how to find the leakage point of the dark water pipe, I hope it will be helpful to you. Once the dark water pipe leaks, it will cause the wall to be damp and even cause damage to the wall, so it is necessary to find the leakage point of the dark water pipe in time and solve the leakage problem as soon as possible.

When looking for the leakage of the hidden water pipe at home, you can use professional instruments to check, or use the pressure water pipe to judge the approximate leakage location, and at the same time, when testing, you can turn off the main valve before opening, close the water inlet switch of the part and then check the leakage position of the car, and at the same time install the water pipe in the direction of the best top.

When there is a leak in the water pipe hidden in the wall at home, the leakage point can be detected by professional instruments and equipment, and this instrument mainly uses a noise to determine the approximate location of the leakage, or tests the leakage point by pressing the water pipe, and troubleshoots the problems of each part in turn.

When checking the leakage point, first close the main valve of the water pipe at home, and then turn on the water head dragon at home for a few minutes, and then close it, and at the same time close the water inlet switch of the bathroom washing machine and other equipment, and then open the main valve to see if the water meter is moving, and judge the approximate part of the water leakage.

Normally, the top of the water pipe is the safest, if the water pipe goes underground, if the water leakage is more difficult to find, the installation of water pipes in a high place, it is easy to find and solve the treatment, but the cost of modification will be relatively high, but this is also the best way to solve the water leakage.

1.If you find water stains on the ground, you can first observe the location and shape of the water stains to see if there is a pattern to follow. If the water stain appears in a linear pattern, it is most likely caused by a leak in a dark water pipe.

2.Listen to the sound: In the vicinity of the dark water mill pipe near the ground, you can use your ears to listen for the sound of water running or leaking. If there is, then the leak point is nearby.

3.Use the water meter: Turn off all faucets and water appliances and observe if the water meter is still turning. If the meter is still turning, it is most likely due to a leaking dark pipe.

4.Use detectors: There are special hidden water detectors on the market, which can be used to detect the location and leakage points of hidden water pipes. The use of a detector requires specialized skills, and it is recommended to find a professional to operate it.

5.Demolition of the ground: If none of the above methods can find the leakage, then the leak can only be found by removing the ground. This method is more cumbersome, requires professional personnel to operate, and will also cause some damage to the ground.

When there is a leakage of the water pipe hidden in the wall at home, the leakage point can be detected by pressure through professional instruments and equipment, and this collapse instrument mainly uses a noise to determine the approximate location of the water leakage, or test the leakage point by pressing the water pipe, and check the problems of each part in turn.

2. When checking the leakage point, first close the main valve of the water pipe at home, and then turn on the water head dragon at home for a few minutes, and then close it, and at the same time, close the water inlet switch of the washing machine and other equipment in the bathroom, and then open the main valve to see if the water meter is moving, so as to judge the approximate part of the water leakage.

3. Under normal circumstances, the top of the water pipe is the safest, if the water pipe goes underground, if the water leakage occurs, it is more difficult to find, and if the water pipe is installed at a high place, it is easy to find and solve the treatment, but the cost of quiet slip will be relatively high when modifying, but this is also the best way to solve the water leakage.

The above is the method I shared with you to find the leakage point of the dark water pipe, and those who need it can learn about it, I hope it can help you.
