In the event of water damage due to defective piping, it may be difficult to find out where the leak is located. However, specialist companies use various leak detection methods to isolate the area where the leak is located.
Source of damage
For each type of pipe break, a moisture measurement is usually carried out first. Therefore, it must first be determined which rooms and components are affected by the damage. The moisture meter detects even small amounts of moisture, so it is possible to find wet spots even where they would not be visible to the naked eye. The measurement thus provides information about where the source of damage can be found. A comparison with the design drawings of the building also allows conclusions to be drawn as to whether there is damage in a fresh water line, a heating pipe or a sewer pipe. Now let us have a proper look at the water leak detection.
With line locators
If a fresh water pipe is affected, all visible pipes and fittings are first subjected to a visual inspection. Frequently weak points of the pipeline can already be found here. By means of a manometer, which is simply connected to a fitting on each floor (for example, a spout or tap in the kitchen or bathroom), a pressure test is made to determine the location of the damaged line section. With special pipe locators the course of the water-carrying pipes in the wall is determined exactly.
In the event that there is a pipe break in a heating pipe, the procedure is quite similar. Visible components, i.e. radiators and pipes, are first checked by a visual inspection. If a pressure loss in the system is repeatedly detected in a heating system, even though water is regularly filled up, this may also be due to the expansion tank, the pressure relief valve or the filling hose. A visual inspection brings these vulnerabilities to light. The pipe search in the wall is carried out using the same methods as for the detection of fresh water pipes.
Track pipe break
Similarly, sewers are first examined for visible defects. Another way to detect leaks in the sewage system is to use stains. If, for example, in the bathroom on the floor tiles repeatedly collect water, although it is constantly wiped, all sanitary fixtures, i.e. toilet, shower and / or bath and sink are operated and the water dyed with each coloring agent. If the accumulating water after a while is also colored, it is clear that the defect is to be found in a sewer pipe. Sewer pipes are also used to detect leaks in various cameras, for example infrared cameras or endoscope cameras.
Another method used to locate a pipe break and leaks in heating or fresh water pipelines is the use of gas detectors. The water leak detection with the help of a gas detector should be left to an experienced specialist company in any case. In addition, the professional supports are a common method to find leaks. It uses a listening device with sensitive microphones that are able to detect the smallest flow noise.
