Often underestimated and yet so important are functioning and intact gas pipes in the house. It is not without reason that the DVGW (Deutscher Verein des Gas- und Wasserfaches e.V.) sets technical standards for a safe and reliable gas and water supply. During a serviceability test, gas pipes are checked for leaks with the help of a leak rate determination. If a leak is detected, it can be repaired immediately.
The SHK Info team shows what exactly is checked and how often this check must be carried out.

Checking a gas pipe - SHK Info demonstrates how to do it
SHK Info shows you exactly how to proceed. The visual inspection is also explained here. This inspection should be carried out annually. The general condition of the gas pipes is inspected and checked for fine hairline cracks, for example. It also checks whether the shut-off devices are freely accessible and functional, whether there is any rust and whether all connections are in good condition.
Carrying out a serviceability inspection
Since not everything can be seen with the naked eye, the serviceability test should be carried out every 12 years. Here, the leakage rate is determined to see if there is a leak. In the SHK Info video, the Dräger P7-TDX is used to carry out the serviceability test.
If there is a leak, it depends on the quantity and decides whether a system has to be taken out of service in the worst case. This is the case if the leakage rate exceeds 5 litres per hour. The system must be shut down immediately.
In order to see where the leakage is, the Dräger GS3 leakage detector is used. This is used to check all the connection points of the gas pipes.
The video from SHK Info clearly shows how important it is to have a serviceability test carried out by a specialist company.
