If you want to check for a leak in a geothermal pipe, how should I check it?

If you want to pry, don't fix it. It is troublesome, it will affect the life of your family, and it may also cause inconvenience to the life of your neighbors. So, how can you quickly tell if your floor heating is leaking?

If there is a water leak, do you really have to go to great lengths to pry a lot of floor tiles? In home decoration floor heating, wall-hung stoves are usually used to bring in floor heating. The wall-hung boiler has a pressure gauge that shows the pressure of the floor heating system at any time.

The underfloor heating system is a sealed circulation system, and only a small amount of water is circulating in the pipes. There is a valve at the connection between the wall-hung boiler and the tap water that stays closed for a long time, and the wall-hung boiler also has a make-up valve that keeps the water replenished for a long time. This double guarantee guarantees that your underfloor heating system has very little water, but any leaks will be seen through the pressure gauge of the wall-hung furnace.

You should look at the position of the pressure gauge pointer and see if your wall-hung boiler has been rehydrated at intervals recently. If so, consider that there may be leaks in the underfloor heating. Some people are very worried about floor heating leakage, and the floor tiles at home have to be prying.

This is actually the practice of the past, especially under the premise that it is difficult to find the leak point by manual experience or past methods, then only a large area of wooden floors and tiles will be pried open. It's the age of high technology. Leaks can be found exactly within a few minutes using thermal imaging instruments.

At most, you only need to pry and repair one tile, and you can get the floor heating leakage repair work. In the absence of man-made damage or other non-resistance damage, the amount of leakage from the underfloor heating pipes should not exceed the hot and cold water pipes for your home renovation.

Pressure should be maintained throughout the installation of underfloor heating. In the north, developers are concentrating on the installation of floor heating, and it is not known whether it is regulated or suppressed. However, in the southern region, the whole process of home improvement and floor heating must be maintained.

If the pressure is found to be incorrect, it is necessary to make up the pressure in time for inspection. After laying tiles and wooden floors, the pressure can be observed through the boiler pressure gauge. Under normal circumstances, the floor heating will not leak, even if someone damages it, there is no need to worry about damaging the tiles and wooden floors in a large area.

Although floor heating belongs to low-temperature heating, its water temperature is generally around 50, and high temperature often accelerates the aging of plastic materials, so if the floor heating pipe used is an inferior product, there will be some problems. For example, during backfill construction, due to the poor toughness of inferior heating pipes, if they are squeezed or collided, there will be some dark damages. The problem may not be particularly obvious at first, but it will be exposed after a while.

Since the construction of the underfloor heating has been completed at this time, it will be more troublesome to repair it again.

Therefore, when buying floor heating pipes, you should choose reliable products, not inferior products. Generally, the floor heating pipe with good quality is characterized by uniform wall thickness and smooth surface. Comfort 100 reminds users to pay more attention when buying floor heating pipes.

In order to obtain durable underfloor heating, in addition to choosing high-quality underfloor heating pipes, the installation of underfloor heating is also a very important link. For this kind of equipment for floor heating, there is a saying in the industry called three products and seven installations, which is enough to reflect the importance of floor heating installation. Due to the increasing development of the heating industry, some unqualified enterprises have joined the ranks of heating.

These companies themselves lack installation qualifications, and their installers are not trained to install the system. Therefore, in the actual installation process, there will be a phenomenon of non-standard construction, which leads to frequent leakage of floor heating pipes.

In the case of water leakage in the geothermal pipe, it can be detected in the corresponding way. For the newly installed floor heating, the floor heating can be detected by suppression. The so-called floor heating pressure is to use a large pressure to detect whether the geothermal pipe has a small leakage or hard injury, if there is no problem under the strong pressure, it can be used normally.

For floor heating that has been used for a long time, it can be detected for water leakage, and it can also be detected by suppression. The pressure test needs to be carried out by professional personnel, and some auxiliary work is also required to be done through temperature detection during the process, and if a water leak is found, the floor needs to be removed and the underfloor heating pipe replaced.

Close the main valve, press the floor heating pipe with a press, and press 8 10 pounds for half an hour. If the pressure remains constant, the heating tube will not leak. If the underfloor heating pipe leaks, its pressure will be difficult to maintain for a long time.

It's best to get a professional plumbing repairman who has a special machine to detect the leak.

Auditory leakage stick: similar to a stethoscope, it is generally placed on the pipeline valve or exposed pipe, and the ear is attached to the earpiece to diagnose whether there is a water leak near the pipeline, and it can also be detected step by step along the direction of the pipeline on the ground to determine the location of the leakage, but the premise is that the pipeline is not buried deeply.

Water leakage detector: mainly used for pavement listening, it is a device that captures the sound of water leakage on the pavement. When the water supply pipeline leaks, the water overflows under pressure to produce a kind of noise, which will propagate along the pipe to both sides, or along the medium to the ground, the water leakage detector is to pick up the sound of water leakage, and convert it into an electrical signal, after corresponding amplification and digital filtering, to judge the accurate location of the leakage point.

This is the method of water leak detection, traditional sonic detection. The location of the water leak can be determined directly.

Line Meter: It is an essential tool for finding metal pipelines in an unknown direction. Knowing where the pipeline is going is an indispensable prerequisite for leak detection.

There are methods, with instruments. There are many instruments for leak detection, mainly to detect the weak sound of the leakage point: electronic leak detector, pipeline leak detector, tap water leakage detector, water leakage detector, intelligent digital water leakage detector, pipeline leakage detector, underground pipeline leakage detector, underground pipeline leakage detector.

The water company has a dedicated leak detection team.

Plug the outlet, then add water to the inlet, make sure there is at least a two-metre high head, mark the water level, and wait a day and night. **Changes in water levels. A low water level is a sign of a leaking pipe.

The leakage of the sewer pipe can be solved by the following methods: If it is a PVC water pipe, you can buy a PVC water pipe to connect it yourself, first cut the broken pipe, and put the interface into one end of the pipe first, so that the cutting position of the other end is just flush with the other opening of the interface, so that it can be straightened, and then send it directly to this end, so that both ends have a certain cross connection distance (length) Then disassemble it and apply PVC glue directly to the inside of both ends and the outside of the two sewer pipes. 2. You can buy waterproof tape to repair the sewer pipe, just wrap it up, and then use mortar waterproofing agent and cement to wipe it on.

3. It's better to find a professional company, if you can't handle it yourself.

First of all, to determine whether it is a PPR pipe leakage, find a plumber and ask him to use a pressure test pump to test the pressure of the PPR pipe at home, this is very easy, half an hour is OK, in my experience, the probability of PPR pipe leakage is very small,,, is there a leakage in the place where the water is used?--Generally speaking, it is the sewer pipe connection that is not well connected, leaking or the ground waterproofing is not done well, resulting in water seepage--- which requires the ground to be excavated, the sewer pipe to be inspected and repaired, and the ground waterproofing to be redone.

The purpose of the installation of underfloor heating is to allow us to have a warm and comfortable environment in winter. However, the floor heating should be laid when it is used, and then I will introduce to you why the floor heating pipe is leaking and how to repair the floor heating pipe leakage.

1. Why do floor heating pipes leak?

1. Pipe quality and service life.

According to Qeeka Home expert Jieyu Bend Bi Shao, some black-hearted merchants make huge profits by selling inferior heating pipes. The processing accuracy of inferior floor heating pipe raw materials is not enough, and the service life is not guaranteed. Therefore, consumers should not be greedy for inferior products bought cheaply when buying floor heating pipe products.

2. The construction of floor heating was damaged in the later stage.

As we all know, three points of materials, seven points of construction. The technical level of the construction personnel varies, and individual construction personnel do not follow the industry norms for construction. Cause damage to the floor heating pipes caused by subsequent renovations.

For example, the decoration personnel use electric hammers, cutting machines, nail guns, drilling machines, etc. on the ground where floor heating is installed. For regular floor heating laying, the whole pipe must be used for each pipe, and no joints are allowed, so as long as the quality of the pipe fittings is qualified, the pipeline itself will not leak. (Hint:.)

The floor heating water pipe is about 3cm from the surface of the backfill layer).

3. Improper cleaning of the coil.

Repaired underfloor heating pipes can also cause water leakage if they are ejectorized. There are generally three methods of cleaning floor heating: chemical cleaning, pulse cleaning, and ejection cleaning. Generally, it is cleaned once every 3 years or so, so please choose a professional one.

Second, how to repair the leakage of floor heating pipes.

If you find a leak in the floor heating, close the inlet and return valves immediately to avoid greater losses. If the leakage of the floor heating pipe is detected, the pressure will drop sharply in a short period of time, and after determining the location of the troublesome friend in the water leakage, the residual water of the floor heating pipe will be released, and then the floor can be chiseled in a small area, the cement layer is removed, and the leakage point is connected with a joint, if the leakage is serious, the pipe needs to be replaced. After the repair is completed, it is necessary to perform a pressure test again to ensure that there is no more water leakage and a water test to prevent debris from entering the pipe and causing blockage.

After the test, roll the floor back on.

As the first choice for home heating, floor heating has been recognized by more and more families, and I hope the above introduction can be helpful to everyone.

In northern cities, geothermal heat is generally installed, which is very convenient for life. Geothermal heat should be careful when installing, and at the same time it should be tested for water leakage, so how to detect geothermal water leakage? Next, I will introduce you to the relevant content, let's take a look.

1. Use the pressure gauge to observe whether there is water leakage. Observe whether the pressure gauge of the geothermal heat changes when the geothermal work is working, if the geothermal water will leak, the pressure of the pressure gauge will decrease, and the value of the pressure gauge will drop significantly. If the geothermal heat is slowly leaking, then the pipe should stop working and cool to a normal temperature, then inject hot water into the geothermal pipe to increase the pressure, and then close the valve on each water separator to observe the pressure gauge, if there is a value fluctuation size is different from others, it means that there is a water leakage.

2. Determine the leaky room. Next, we need to open the valves of each return pipeline, and then observe the phenomenon of circuit pressure reduction, the circuit with obvious pressure reduction is leaking, and after knowing the circuit, you can determine which room has geothermal water leakage.

3. Determine the approximate area of water leakage. The room temperature is heated to a constant temperature, then the geothermal temperature is controlled at the same temperature, and then the infrared tester is used to measure the temperature of each area of the room. If the temperature in some places is irregularly distributed, it means that the leak area is in this area, because the temperature of the leak will be higher than in other places.

The hot water coming out of the leak will come into direct contact with the floor, causing the floor to be warmer than other pipes, so that the specific area of the leak can be determined.

4. Find the leakage point. After finding the leakage area, we need to find the specific leakage point, the temperature at the center of the leakage is the highest, and the infrared tester can detect the leakage at which location, and the repair can start after determining the leakage point.

In fact, we just need to learn how to find the leakage point to solve this problem, so how can we detect the location of the underground water leakage?

1. Use the leakage tool or electronic side leakage instrument to measure the leakage point at the exposed position of the pipeline, see if there is a leakage sound to determine the leakage point, and then narrow the audiometry range after determining the leaking pipeline. If the sound of the listening point is louder, then the leak point is closer, farther and smaller.

2. After determining the location of the pipeline leakage, use electronic instruments to magnify the leakage and find the accurate position.

What to do if the water pipe is leaking.

1. Water pipe joint leakage, usually in this case, it is due to the fact that the joint of the water pipe is not directly connected, and there is no sealing treatment to appear such a question, in such a situation, first we have to disconnect the water source, remove the screws of the two joints, and then re-tighten the raw material belt around the thread. If it's because it's aging, you'll need to replace it with a new one.

2. If the sewer pipe leaks, it will be more difficult to deal with, and it may also affect the residents downstairs, so it must be dealt with immediately. Usually the sewer is used in PVC pipes, this can directly cut off the leaking section, and then replace the casing, apply glue twice, and wait for drying.

3. The reason for the leakage of the iron pipeline is that the internal backlog of dirt has caused rust and corrosion of the water pipe for a long time, after finding the leakage point, if the leakage point is relatively small, you can cut off the middle part, and then connect it with a joint, if the leakage area is large and the rust and corrosion are serious, the whole pipe must be replaced.

When checking for water leakage, be sure to turn off the water and power supply, the water will conduct electricity, and it is easy to have the danger of leakage, and then you can simply do a good job of plugging the leakage to prevent the flow to other places. The above is a simple way to check for sewer leakage and encounter water leakage, I hope it can help you.
