Frequently Asked Questions

In everyday life, you encounter many questions about regulations and applications. Here are some frequently asked questions about gas installations and clear answers to them.

Digital devices work more precisely, are quicker to set up, are often multifunctional and enable direct report generation via app or PC software. Esders measuring devices not only document digitally, but also transmit the measured data as a documentation report when using our online portal, Esders Connect – always available and right at your fingertips.

A visual inspection of a gas installation should be carried out once a year – ideally by qualified personnel. Every twelve years, a serviceability test by a specialist company is also required. This involves checking the gas pipe for leaks and safe operation. Before commissioning, a gas installation must be checked for leaks – usually with a test pressure of 150 mbar. The test must be carried out in accordance with standards and fully documented.

The tightness of the pipe, accessible and functioning shut-off valves, the pipes being in perfect condition and compliance with TRGI specifications are key points. Gas odours and explosion protection must also be taken seriously. If in doubt, inform specialist personnel and the network operator immediately.

Leak testing, load testing, serviceability testing and leak detection on internal pipes are among the key tasks.

This is required no later than ten years after the date of manufacture. However, many manufacturers recommend replacement after five years – especially with frequent use. Pressure reducers and hoses should be checked for damage before each use.
