How to detect floor heating leaks? What can be remedied?

First, the inspection method.

1.Check by suppression test.

The best and most effective way to check for water leaks in underfloor heating is to use a pressure test. First turn off the floor heating, and then use the manual pressure method to press about ten kilograms of floor heating, and then observe, if the pressure does not drop, it means that there is no water leakage, and the pressure of the occupation has dropped, that is, water leakage.

2.Confirm by looking at the pressure gauge.

There will be a pressure gauge at the inlet valve of the floor heating, if the pressure gauge drops pressure in a short period of time, then it is very likely that there is a water leak.

3.Observe the water situation on the ground.

Second, the treatment method.

If a floor heating leak occurs, the first step is to immediately close the inlet and return valves of the floor heating to minimize the damage. Then the water from the floor heating pipes is released, and the floor can be pried open for repair after the leakage point is determined, and the leakage test must be done again after the repair is completed, until it is confirmed that the floor is re-laid.

But in fact, if you are not professional, it is best not to pry the floor casually to repair it, you can close the valve after determining the leakage, and then find a professional maintenance personnel to come to repair it. This is a good way to avoid further damage to the floor heating and to avoid prying the floor in vain.

If you run to the door downstairs and say that your house is leaking, and the leakage is not a toilet, it means that your floor heating is leaking, and it will also cause water on the ground in your room.

If it is a relatively small water leakage, it is generally not visible, and it needs to be found with the help of other tools, and the pressure gauge can generally be observed to judge whether there is a water leakage. Observe whether the floor heating pressure gauge changes when the floor heating is working, if the floor heating leaks, the pressure gauge will decrease, and the pressure gauge value will drop significantly.

How to detect small water leaks.

Step 1: Use a pressure gauge to observe whether there is any water leakage.

Observe whether the floor heating pressure gauge changes when the floor heating is working, if the floor heating leaks, the pressure gauge will decrease, and the pressure gauge value will drop significantly.

If it is a slow leakage, we first stop the pipe from working and cool it to normal temperature, when the floor heating temperature is cooled to room temperature, inject hot water into the floor heating pipe to increase its pressure, so that you can test it by closing the valves on each water divider, and then observe the pressure gauge, if there is a numerical fluctuation that is different from the others, it means that there is a water leakage.

Step 2: Identify the leaky room.

Then we open the valves of each return pipeline, and then observe the phenomenon of circuit pressure reduction, the circuit with obvious pressure reduction is the leakage circuit, after knowing the circuit, we naturally know which room is leaking.

Step 3: Determine the approximate area of the water leak.

We heat the indoor temperature to a constant temperature, and then control the floor heating temperature at a temperature, and then use an infrared tester to measure the temperature of each area of the room. Because the temperature at the location of the leak will be higher than anywhere else, the hot water coming out of the leak will directly touch the floor, causing the floor temperature to be higher than the temperature of other water pipes, so we can identify the leak area.

First, check all the connections of the branch and observe them with the naked eye.

Open the valves of each circuit to see which circuit has a pressure drop, and if there is a significant pressure drop, it is a leaking circuit.

Close the watertight circuit, pour water into the floor heating pipe, adjust the water temperature to the highest point, and circulate the heated water flow of the floor to the hottest place is the leakage point.

How to repair a leaky floor heating pipe.

1.Find the cause of the leak and determine the location of the leak. 2.

The residual water in the floor heating pipe is released, and then a small area of the floor is chiseled, the cement layer above is removed, and the leakage point is connected with a special joint. 3.After the repair is completed, a pressure test is conducted.

If the indoor water pipe is buried in the wall, you can use the water pipe pressure test method to determine whether it is really leaking, first close the main valve, close all the faucets, showers, etc. in the home, and then remove one of the faucets for pressure test, press the pressure device to about 10 kg, and observe whether the water pressure has a pressure drop problem, if the pressure drops, and it is very serious, it means that there is a water leakage problem, next, the pressure test will continue, if the pressure also drops, you can judge that there is indeed a water leak.

1. Observe the change of pressure gaugeUnder normal circumstances, if it is determined that the floor heating is leaking, the pressure gauge will generally drop pressure in a short time, when it is determined that it is a slow leakage, the first thing is to stop the operation of the pipeline, after the floor heating surface is cooled, after the pressure is injected with hot water, the valves on the water separator are closed respectively, and the pressure gauge is observed to determine that the pressure gauge has not changed.

2. Determine the water leakage circuitOpen the valves of each circuit respectively to observe which circuit has a pressure reduction phenomenon, and the general circuit with obvious pressure reduction is the water leakage circuit. After determining the leakage circuit, close all the circuits without leakage, and then fill the floor heating pipe with water, adjust the water temperature to the maximum temperature, and circulate the floor heating water. At this time, the pressure gauge will gradually decrease, when heating, pay attention to maintain the pressure value of the floor heating pipe, after the leaking floor heating circuit is activated, and then use the infrared thermometer to measure the surface temperature.

3. Determine the leakage pointAs time goes on, the surface temperature rises gradually, and the temperature of the identified leaking pipe will rise very high, forming a peak at the leakage point, where the temperature of the leaking point will be much higher than the temperature value of other parts of the pipeline. When the leakage point area is determined, the center point should be determined, and the position of the center of the leakage point is usually the place with the highest temperature, according to which the user can roughly determine the center position of the water leakage, and then a small area of ground excavation can be carried out to inspect and repair the floor heating pipe.

The method of floor heating leakage is as follows, 1...Check by suppression test, 2Confirm by looking at the pressure gauge.

3.Observe the water situation on the ground. After determining that it is a water leak, you can immediately close the inlet and return valves of the floor heating, and then let professionals come to repair it.

Floor heating is a kind of heating equipment that many families will use, and its wiring pipes are buried in the ground, so it has this name. It is precisely because its system pipes are underground, so floor heating leakage often occurs, which will not only affect the effect of indoor heating, but also shorten the service life of floor heating.

It's easy to identify if there is a leak, look at the pressure gauge on the inlet valve in your house to see if there is any change. Observe whether there is water and humidity on the ground, and whether the indoor temperature changes. If the leakage is serious, you don't need to find the leakage point, it is estimated that you can see it with your eyes, and if you find that the leakage is marked, close the valve quickly to avoid damaging the ground.

1. There is a special instrument specially used to detect the leakage noise of underground pipelines Underground pipeline leakage meter. When the fluid in the pipeline escapes from the leak under a certain pressure, noise will be generated and can propagate along the buried medium to the ground or along the pipeline. As a result, it can accurately determine the location of the leak point.

2. Pressure tests should be carried out during the construction of floor heating and when the project is completed to detect leakage points. The floor heating test pressure is generally more than twice the heating pressure, and the pressure test time is more than 15 minutes. For specific suppression steps, please refer to the site of the floor heating acceptance precautions - how to accept the floor heating article.

3. It is best to backfill the floor heating with pressure, so that if the pipeline is accidentally damaged during construction, the water leakage can be found in time. In addition, it is best to choose a pipe that can be connected by hot melt, such as PR RT floor heating pipe, which is more convenient to maintain.

Floor heating leakage to check the leakage point:

1. Confirm whether the floor heating is leaking through pressure, and confirm the leakage circuit.

When there is a suspicion of a water leak from the floor heating, you can use the method of pressure test to confirm whether the floor heating pipe is leaking (note that the water pressure test must be done). If there is a water leak, the leaking circuit can be detected in the same way.

2. Determine the leakage point of floor heating.

Use the floor heating leakage locator to detect the leakage circuit and determine the leakage point.

3. Open the ground partially.

After determining the location of the floor heating leakage point, local excavation should be carried out, and the size of the excavation surface should be convenient for repairing the pipeline. When excavating the ground, it is necessary to operate carefully and be familiar with the direction of the pipeline to avoid the pipeline being damaged again.

4. Repair floor heating pipes.

When repairing underfloor heating pipes, be sure to clarify the material of the pipes. If it can be hot-melted, it should be connected by hot-melt (such as PE-RT pipes), and if it cannot be hot-melted (such as PE-X pipes), it should be connected with a star joint or snap-ring connection.

5. Suppression test.

After the leaking pipe is repaired, the repaired pipe circuit is subjected to a pressure test.

6. Backfill and restore the ground.

After the pressure test, after confirming that there is no water leakage in the problem circuit, the floor heating pipe is backfilled and the ground is restored.

Causes of underfloor heating leaks

1. Pipe quality and service life.

In order to make huge profits, some inferior merchants use some inferior heating pipe raw materials that are not pure, and the processing accuracy is not standard enough, and the service life is not guaranteed, or they are eager to buy cheap inferior products.

2. Destruction of floor heating in the later stage of construction.

The construction quality of heating enterprises in various places is uneven, and some construction personnel do not carry out construction in accordance with industry standards. For example, when laying the infill layer, workers must wear flat shoes and use a flat shovel to work from the inside out, and if the operation is not carried out according to the specifications, the floor heating can be easily damaged.

3. Follow-up decoration damage.

Many floor heating leaks cause damage to the floor heating pipes due to subsequent renovations, such as the use of electric hammers, knives, nail guns, drill bits, etc. When using underfloor heating on the ground, the whole pipe must be used for floor heating, and joints are not allowed, so as long as the quality of the pipe fittings reaches the rated value, the pipe itself will not leak.

4. Improper cleaning of the coil.

Remember not to use the repaired pipes not to use the projectile type to clean, generally speaking, the cleaning method of floor heating with chemical cleaning, pulse cleaning and flushing cleaning, generally in 3 years to clean once, it is recommended to ask professionals to clean.

Hello, glad to answer for you! The way to detect the leakage point of floor heating: 1. Check the connection of any pipe at the connection of each manifold is the most frequent location of water leakage, and the connection of the metal parts of the floor heating and the connection between the manifold and the coil is a high-incidence area, which is easy to cause water leakage at the interface.

2. After the pressure test excludes the connection parts, you can judge whether the floor heating pipe is leaking through the pressure test. Close the main valve of the floor heating, press the floor heating with a manual press, and wait for half an hour when pressing 8 10 kg. If the pressure can be kept without dropping, it means that the heating pipe is not leaking.

Under normal circumstances, if it is confirmed that there is a leak in the floor heating, the pressure gauge will generally drop pressure in a short time. 3. Determine the water leakage circuit to open the valves of each circuit respectively, and observe which circuit has a pressure reduction phenomenon, and the circuit with a significant pressure drop is the water leakage circuit. After confirming the leakage circuit, shut down all the circuits that have no leakage, and then fill the floor heating pipe with water, adjust the water temperature to the highest temperature, and circulate the floor heating water.

4. Confirm that the water leakage point gradually rises with the extension of time, and the surface temperature gradually rises, and the amount of hot water at the water leakage point is more than the normal position, and the heat is also higher. When the leakage point area is determined, the center point should be determined, and the location of the center of the leakage point is usually the place with the highest temperature. Based on this, the user can roughly determine the center of the leakage, and then carry out a small area of ground excavation, and check and repair the floor heating pipes.

In addition to this, we have the option of using an infrared imager for testing. With an infrared imager, the leak area is scattered and brighter. The normal underfloor heating area is dark red, and the leakage point is bright white and easy to identify.

<><What is the method of floor heating leak detection?

1. Use a pressure gauge to detect the floor heating pipeline, if the pressure value of the pipeline is detected to drop significantly, then it means that the floor heating pipe has leakage.

2. Open the valve of the return pipeline in each room and conduct the pressure test separately. If the pressure drop is obvious, it means that the return pipe of the room is leaking.

3. Then use the infrared tester to test the floor heating pipe into the stool, if the displayed temperature is the highest, then it means that the point is a leakage point.

Why do underfloor heating pipes leak

1. If the material of the floor heating pipe is an inferior pipe, it will not be used for a long time, and it will be damaged, resulting in water leakage. In order to avoid this situation, it is necessary to choose a reliable floor heating company to cooperate.

2. The reason for the leakage of floor heating may also be that the construction of the construction search workers does not meet the requirements, and the floor heating construction is not carried out in accordance with the relevant regulations, resulting in a relatively short service life.

3. It is also possible that the installation of floor heating itself is not a problem, and the quality of the materials is also in line with the requirements. However, when the cutting machine or drilling machine is used in the later interior decoration, the floor heating pipe is damaged. In addition, the floor heating pipe laid should be a whole pipe, and there should be no joints.

4. In the process of use, the floor heating pipe tray needs to be cleaned regularly, otherwise it will affect the heating effect of the coil. If the coil is not cleaned correctly, it will lead to leakage in the floor heating pipe, so special attention needs to be taken.

What is the method of floor heating leakage detection, and why there is water leakage in floor heating pipes, it will be introduced here first. Floor heating leakage is to check what the specific cause is, and then do maintenance work in time to ensure normal use in the later stage.
